How do you choose an engine oil? Is it just a case of "more expensive is better"?

>>15256033
I use Fuchs or Penrite oil of the recommended viscosity. No reason for brand loyalty. I just know they exceed SAE etc. so that's all I need.

>the very things that need to be lubricated during start aren't magnetic(bearings)

Magnatec is pretty legit, i use it on my xt forester because of high miles. But i use penrite in my race car because ive seen some very good before and after track composition tests
Magnatec sucks big iron cock. It is literally pleb oil, marketed as good oil, so plebs with slightly more money will buy it.

The oil uses magnetic particles to adhere better to critical surfaces.

Look up the past oil threads that appeared in /o/ as the advice and questions were all in there already. It's too bad the thread spammers and trollers make lots of stupid threads to shove informative threads off /o/.
In my families and my own daily drivers I use supertech from walmart. can't beat $2 a quart.
valvoline vr-1 and torco gear/trans oil in my street/track car.
Clean cheap oil is going to do a better job at lubrication than expensive dirty oil. Depends how many fucks you give about your vehicle. I wouldn't go putting dollar store oil in a brand new car that's for sure.
On a side note...
What's with people putting diesel oil like rotella in their gas engines? Does it really work better, or???

The additive package is better for older engines with flat tappets. If you have roller lifters then you don't need to worry.

I can't for sure tell you the pros/cons of diesel oil in a petrol engine but...
My Dodge truck had a valvetrain tick, I did an oil change with 20w-50 and it quit.
My Lexus consumed about 2.5 quarts of oil a week, I started using 15w-40 and it only uses about 1/2 a quart a week now.
It's only anecdotal but take with that what you will

5 quart jugs of synthetic oil are cheap at wal-mart. Mobil1 FullSynth is $22.97 at my local store this past week. So, there was the guy that paid $2.xx per quart of SuperTech (wal-mart's plush house brand) conventional oil which makes it $10 per jug, but the SuperTech Full Synthetic is $17 per jug. I think for the $7 more, he would have had a great deal.
.
The archived engine oil thread for conventional versus synthetic oil is at:
https://archive.4plebs.org/o/thread/14985876/
.
One has to pay attention to how oil is used in your engine too. For example, some engines have a lot of start and stops because they are either hybrid or ECO type engines. You will want not just an oil that is good with a lot of start/stop activity, but a filter that withstands constant pressure spikes. If you use a regular filter (purolator or low end fram), they may have tears. Purolator had been getting that problem lately. Fram Ultra filters have a metal mesh surrounding the filter and that mesh even goes into the pleats with the filter media. The mesh seems to prevent tear and blow through from pressure spikes especially from ECO engines that were stopped at a traffic light, but the driver has just gunned the engine. At that moment, not only did the ECO engine just start, but it is also accelerating hard due to the driver having a jackrabbit start.

I had bought a quart of pennzoil platinum for like 25.50 at wallyworld a couple weeks ago, and was curious as to if it was any good.
>>15259896
I guess all you need are filter changes. No need to visit the proverbial JiffyLube.
What caused your Lexus to get up to using 2.5 quarts per week? A broken piston ring? Was that change gradual over time? Or was it a sudden change in oil consumption?
Since 2.5 quarts per week would leave a lake on the floor, it wasn't an external oil leak.

>I had bought a quart of pennzoil platinum for like 25.50 at wallyworld a couple weeks ago, and was curious as to if it was any good.
Those are conventional oils in that picture and at that site URL. Nothing for your Pennzoil Platinum synthetic. The archive thread at >>15259964 has a URL to a oil database though.
Easy
Thicker the oil, the more your engine parts lasts
The thinner the oil, more gas mileage
>>15260322
So I just need to get oil that's not too thick and not too thin to get the best of both worlds. Problem solved. Crisis averted. Drinks are on me.
>>15260388
That way of thinking is from the old world.
Today's engine bearings and modern journals are made to have lubrication occur from hydrostatic separation of the surfaces because oil is incompressible but will slowly squeeze out under the pressure. But before that happens, the oil pressure causes new oil to get into the space due to movement of the surfaces.
The key thing in modern cars is to have oil flow. So too thick a vicosity impedes oil flow.

I did a bunch of research on oil and oil filters on sites like bobistheoilguy. Ended up using Mobil 1 extended performance full synthetic and the Mobil 1 M1-110 filter on my Accord. I'm pretty happy so far
>>15260492
>What do you guys think of this? guy claims all that really matters is psi loading and shearing.
The info varies in value based upon what you know about your engine and how it uses oil. Most of the usage importance lies with bearing where PSI is important. But there are also gears, rollers, sleeves, and impact areas (older cam design). Only you know the combination percentages of these items for your car and how much force is applied to them based on the design. If you don't know, then all you can go on is something like his PSI and shearing because without other knowledge, those are the only numbers that matter to you at that time. As you know more about your car, you can then decide if those numbers are insufficient or inappropriate.
>>15256033
Always used Quaker State in my cars. That shit is good on the engine. I did also try the Castrol gtx, but mostly I use it if I get a car with higher mileage, just to kinda wash out the old oil over a couple of hundred miles. And then I put in the Quaker State.

at the end of the day, you can't go wrong with anything that has a SN / API cert on it but some oils are clearly better than others, pennzoil being the current choice of bob is the oil guy shitposters (this is because of its low volatility and high amount of molybendum)

>>15256033
I usually pick whatever is cheapest. Oil is oil.
It's the additive package that matters. As long as you change your oil regularly enough it doesn't really matter.
I do try to go full synthetic though.
Whichever full synthetic of Castrol Edge, Pennzoil Platinum, or Mobil1 is on sale at the parts stores with a GOOD filter(read; not K&N) at the time.

Lots of people buy the conventional oil jugs at walmart for $11 to $13 for FIVE quarts and it is SAE rated oil. So it meets specifications and is usa made so no worries about fake chinese certifications. That amount of money is actually significant to a lot of people. The wealth gap is getting larger all the time too thus exacerbating the problem.

Type that question into google and it will tell you. Google seems to have adapted many of the language features of ASK.COM where you could ask questions and get some search results. ASK is still better at targeting results, but google has a bigger set of choices to pick from.
The answer relates to the types of lubricants 1 to 4. But the ones you are talking about are types 1 through 3 with 3 being full synthetic.

>Nothing to do with the fact he has a page dedicated to advertising for them..
He's successfully monetized his site and some of the regular posters are official industry personnel. HOWEVER, some of these forums, bobistheoilguy included, are quite useful because these industry people do answer questions and even provide help. For example, the Fram USA technical director is regularly in the forums. They are aware that the chinese parts suppliers make unauthorized substitutions and even unauthorized manufacturing dimension changes to products. So for those who are reliable long time forum members (thus not fake one day trolls) do get such filters, take them apart carefully, and identify the suspected problem, the tech director asks for those filters so they can find out which factory is doing this. In return, all the shipping is paid of course and the forum poster gets a bunch of filters of his choice as reward for the info.
But if you simply appear to spout hate, spit on everything, then you won't last long on moderated forums. It's why those trolls in /o/ that make trash threads to force good threads off also don't survive in moderated forums.
However, on those moderated forums, you don't get the complaints about Jiffylube's upsell scams and other problems. The moderators delete all unsubstantiated highly-negative comments like that and jiffylube might even sue the account since it's not anonymous and can be tracked to the ISP account. So there's pluses and negatives for those forums.

IIRC Audi's come from the factory with Liqui-moli oils and fluids.
Amsoil makes a pretty good product but have a top notch website to reference fluid fill amounts and types.
Shell Rotella is excellent quality and value for diesel engines.
Choosing oil and fluids is more of an application specific thing than most people think.
Oil is not simply just oil, such is the reason why it's called a formulation.

More expensive is better might work for some things, but definitely not for motor oil in the Americas where the industry is driven by the smoke and mirrors of marketing more than anything else.

K-Mart in my town recently closed.
Had "no name" non-branded 10w-30 oil for $0.50 a quart.

Also got 10 Purolator filters for muh van for like$0.70 each
So, yay for me on the demise of the US economy?
>>15272036

Unfortunately, the higher priced gimmick products make profits by hiding behind the reputation of other products. They do this with the phrase "You get what you pay for" implying that their product is greater than other solid products similar to theirs in nature (but not performance).
>...where the industry is driven by the smoke and mirrors of marketing more than anything else.
Well, the advertising stokes the car owners' emotion of "more is better" in trying to sell things. Oil boosted by graphite is one such thing. Then there was the Slick50 PTFE advertising that successfully drove sales of their Slick50 oil additive. All I can say is that never buy an additive that says "shake well" because that means to me it's going to settle down on the bottom of the oil pan as sludge after you stop driving. And lo, it did.
>>15272707
>So, yay for me on the demise of the US economy?
It seems like Sears is going to die. In my prosperous area, the Sears automotive center had plenty of business, and Sears was trying to sell it off. That doesn't make sense unless the company is really just trying to get cash to stay float another year. It's cannibalizing itself with the current management that is only profiteering by selling off the parts. It's like T.Boone.Pickens took over the company and drove it down in order to sell its parts off.
This past tax season, I went by once again to look for the H.R.Block tax service that used to be there. And once again, nothing for the 2nd year. They'd rather leave the space empty and unused than to have a service that also brought possible customers into the store. I know two separate times that I bought something just because I was there, and other times I walked thru the store. I wondered if it was some sort of corporate sabotage? Instead, Wal-Mart had tax services in their store and shoehorned it into narrow cubicles in the middle of their largest aisles. I didn't use that since wal-mart has more than enough money.
But it seems that only companies selling products made in China can compete in the general goods category. Sears hung firm to selling made in usa goods too long. It also needed to treat its staff less well and more like wal-mart's method. It changed that too but it's too late now it seems because the reputation has left it. I hardly even see sears advertising anymore, but back when I was a kid, there was always a lot of advertising from them. Wal-Mart is a huge profit source for China and a big reason for the demise of many stores that tried to give a living wage. I can say that because I remember how it was immediately before wal-mart came and how it was immediately thereafter. Wal-mart makes most of its money from social welfare too since it is almost the sole place many such people shop at.

Inflation adjusted income per capita is a linear rise since the 90s.
Housing market has fully recovered.
unemployment has recovered to a historical average.

Idiocy: The Post.
Income per capita is flat
Housing market is shit, houses 30% below value and huge areas abandoned and foreclosed.
Unemployment? Ha! Real U-6 unemployment is almost 20%, but King Nigger Ofucko changed how unemployment is counted.
And the US Dollar on Purchasing Power Parity in on a 10 year decline, thanks to runaway US debt and 0% interest rates.
Sears and Kmart are dieing because a Hedge Fund Billionaire, strong-armed his way to buying the company, took it over, he didn't know shit about retail, and subsequently killed the brand. Same thing happened to J.C.Penny.
Of course it doesn't help that 96 Million Americans are out of work, that 45 Million Americans live on Food Stamps, that entire cities are empty of any form real job.

The american auto industry reflects many problems in business and how america has changed. Some people would like to ignore that though.
>>15274442
>Unemployment? Ha! Real U-6 unemployment is almost 20%, but King Nigger Ofucko changed how unemployment is counted.
Actually, President Bush did. He made the changes in a desperate move to not go down in history books as the one that caused huge unemployment. He also made other changes on the index such that subsequent RE-employment of those previously unemployed people didn't include that they were at lower wages or had switched from fulltime to part-time employment. Thus, more of the part-time employed were counted. Some critics also mentioned that some people were counted more than once, but I didn't understand that and ignored it. I wished I had paid more attention.
Another problem about people who use statistis vaguely are those who say income has risen for ALL americans. That is disingenuous because if the top 1% were removed, income has drastically fallen when adjusted for both inflation and purchasing power. That's due to the widening gulf between the wealthy and everyone else. The gulf continues to widen. The gulf matters because everyone else has to make their own fortunes out of the diminishing piece of pie. The top 1% own over 50% of the pie, so that means the other 99% has to make their own wealth out of the other 49%. BUT, the top 5% own over 70%. So that actually means the other 95% have only 29% of the pie. It's no wonder that people are vaguely unhappy after all those inheritance changes as well as taxcuts for the rich have contributed massively to the problem. Prosperity has been reduced unless you do as the republicans want with the statistics like that post in >>15272971 which is what rush limbaugh would say.
So it's too bad the vibrancy in the USA auto market is lost due to the changes in the american public's earnings. The everyday cars will be less imaginative as a result.
Can I get an advice for the best motor oil for my car? It's a 1997 Saab 900 2.0T (136 kW)

You should go read the posts on Saab high mileage oil changes at Saabcentral.com or this post which echoes many of the same observations:
http://www.bobistheoilguy.com/forums/ubbthreads.php?ubb=showflat&Number=111481
Basically, for high mileage Saab 900, the cruid inside reduces the amount of oil leaking. If you switch to a super cleaning full synthetic like Pennzoil platinum ULTRA, it will clean out the crud that is lodged against the seal or in the seal and your car will leak oil a lot faster. High mileage oils have some additive that swells the seals, but if you stop using that stuff, the oil leaks would resume only even more. So automatically switching to full synthetic is not always the best choice as something can actually be "too good" for the situation.

Supertech 5w-30

Thanks! Will try to find the one that I will stick to.
Someone on a Saab thread sugested to stick to the one that's suggesteed by manufacteur (was it Mobile1 5w30?) or something that's a bit better (I think it was Castrol). I don't remember cause it wasn't time for an oil change yet but now the time for the first oil change has come.
Also does the climate means something when searching for oil? I live in northern europe. It tends to be really cold in winter and hot in a few summer weeks.

>Also does the climate means something when searching for oil? I live in northern europe. It tends to be really cold in winter and hot in a few summer weeks.
Really cold means 0W or at most 5W oil. 10W is way too thick for cold weather starts. The 2nd number is for when it is hot. Your drivers manual should be downloadable for free if you don't have a physical one. It will say the recommended oil, but you can also call your dealer for their advice and consider the two.
Chances are for a 1997, I guess the official oil would be 5W30 since that was the rage at the 1997 time period. Nowadays, 0W30 is a choice for colder weather. In the USA, new cars have either 0W20 or 5W20 for OEM oil choices, but that is model year 2016.

Was using Rotella T6 in my Miata and it used to help my ticking, but after using it for about 15k miles I switched to Mobil 1 5w30 high mileage and tick went away and hasn't come back
I buy cheap generic oil when its on special and stock up a 5L jug or two in the shed until I need to change out oil.
Has anyone tried a thinner oil in hopes to increase gas mileage?
>>15278239
The thing is, at operating temperature 0w-30 is the same viscosity as 10w-30.

>what is sae 10, 20, 40, 50, and 60
>>15278239

It only changes about 0.5 mpg
If you care to risk your engine to gain a mere 1/2 mpg increase in fuel economy, go ahead.
Pennzoil platinum for the past 20k and Tokyo roki filters since acquisition. Might try a different oil in winter to see if it will solve piston slap. So far car likes it.
My Subaru has 210k on it should I try high mileage synthetic?
>>15278403

Can you get straight 10 or 20 at your parts store? And how would 40, 50, or 60 save fuel?

Even the 5quart jugs of conventional oil brands at Wal-Mart have an everyday price of $11 to $15. The SuperTech full synthetic 5qt jug is $17.97 so that is a nice price for oil. At least in the usa, you don't need to wait until your supermarket has a sale if you just go to wal-mart where the jugs have a commodity price. It's the one quart bottles that still have the normal high price.

Guide to oil choose:
(I'm talking about engine oil)
First 2 digits (before "W"):
15 -> Old cars
10 -> Regular cars, no turbo
5 -> Turbo cars
2 last digits (after "W"):
40 -> Regular
30 -> Diesel particulate filter equiped car
Basic rule: In most case, use 10W40. If the car have turbo, use 5W40.
>>15280527
Or better yet, read the owners manual.
My N/A v6 car uses 5w20
>>15280527
Most 4 cylinders on the road use 5/30. Slightly older, most use 10/40. You shouldn't be giving advice.
>>15280550
This is actually teh best way.
>>15280559
The guide is made on my french experience.
What about conventional vs hybrid vs fully synthetic? Just use whatever was in there last?
>all these virgin nerds arguing about oil
just go to a forum with a community based on what you drive or ride.
my daily/only is a kawasaki. go to its forum, see past threads. even make my own. i ride in a really hot climate so i use 20w-50 all summer then back to 10-40 in the winter. synthetic valvoline wet clutch.
boom. done. literally nothing more needed to be considered when getting oil. the only time youll wanna know more is if you're racing frequently cuz your gonna be blowing up your motors every race anyway.
faggots.
>>15278239
>Has anyone tried a thinner oil in hopes to increase gas mileage?
Some people do that by moving to a thinner oil at operating temperature. Thus, instead of 5W30, they may move to 5W20 which is quite a bit thinner at operating temperature. When oil is thinner, the oil pump still runs at the same rate, so the oil pressure will drop some at the point after the oil filter restriction. Of course, thinner oil also flows through the filter easier, so the oil filter doesn't reduce the oil pressure as much. As long as there is sufficient oil pressure to deliver the necessarily volume of oil, the thinner oil still provides sufficient lubrication and reduced energy loss since there is less loss to viscosity-type shearing losses.
The difference and mileage gain of switching to a lower viscosity oil is described at:

>Basic rule: In most case, use 10W40
Your advice is from the 1980's and is not applicable to modern cars. Another problem with high viscosity oils like 40 weight is that pressure spikes can cause that thick oil to crumple the pleats of oil filters or even punch a hole in some like the purolators. A filter designed for a certain car may have filter media created for that expected oil viscosity. If you use thicker oil than expected, the filter may crumple.
As others have said, You should not be giving advice out of another era of motoring. In an archived oil thread, someone even posted a specific example of where a good old practice was now a bad practice with new cars and should not be done. The old threads are worth reading. It's a shame the thread trolls keep making a lot of trash threads to force threads that have knowledge in them to go to page 10 to die.

Do you realize how small the differential pressure across an oil filter is compared to the pump's discharge pressure?
>>15256033
I usually use mobil 1 synthetic just because. Guess I made a habit out of using it without really thinking about it. If I had to pick another brand i'd go with royal purple.
Mobil 1 0w40
The engine parts are so clean they don't even have a slight coating of varnish on them. I also get the oil lab tested to verify it's still good when I change it out.

See >>15259964 for the link to the archived /o/ thread on "conventional vs synthetic oil".

That poster might be thinking of two types of usa cars such as Hybrids and ECO cars which have engines that frequently shut down and start up again. For ECO, the driver can floor the pedal and the car suddenly starts up and at the same time there is high RPM and thus higher oil pumping rate for a combined pressure pulse on the filter. It's why Fram, among others, put wire mesh in some filters made for those cars to stop the pleats from crumpling.
