I just bought my first carand I couldn't be happier, but something has been bothering me since I don't know much about cars themselves.
Is unleaded gas a meme or should I be worried? I constantly put gas in a westar nearby and it says super unleaded and its just 1.85.
It's just a meme right guys, I shouldn't be worried... right?

Super unleaded makes your car go faster.
Be careful you don't get a speeding ticket.

The fuck?
What is the meme about unleaded?
Cars before were built with shitty tolerances, and the engines needed lead to help it perform better. These days, you cant use lead due to the damage it causes the catalyst, but also because you really don't need to use it anymore.

Why unleaded cheaper though, I don't get it.
I see places with just regular and are like 2.33 or something.

It's unleaded, but all gas is unleaded now. Regular, premium, and super unleaded have different octane levels. So you pick the octane level that the manufacturer tells you. If you use a lower octane than they say you'll lose power, a higher octane than they tell you and you are just spending money on nothing.

lead was used in (old) engines because the exhaust valve's would overheat & melt/deform. lead cooled it a bit off to prevent that from happening. now valve's are made out of a much harder type of steel which can withstand the intense heat.
but if you have an old car which is supposed to use lead, you can still drive it without problems. just keep it on low revs. and if you want you can convert your engine to unleaded.

You are the man, thanks.

ayy glad im not a ricer cuck

it's not really that big a job, just change the valves and valve seats and it's done.

How much would you charge for it?

>shitty tolerances
No. Engines built before 1972-ish didn't have hardened seats for the exhaust valves. The lead was used to cool and lubricate the valve as it opened and closed.
If you run and old engine for long periods of time and/or high load with unleaded gas the exhaust valves will eventually hammer themselves into the head and "sink" causing a loss of compression.
