Gasoline octane...

what should we use for our cars??

i was curious to this topic because people always seem to have their own opinions about it

what are the true facts about the difference between using premium, midgrade, nd regular, no bs

[rexload]

absolutely no difference in our cars. save your money and get regular

Your car is really only designed to work on a certine octane. Putting in diffrent octane will only help if you have pre-ignition ( Am i refferring to the right thing? ). I wonderd the same thing and looked into it. Basically what i read was a higher octane gas wont matter in our cars due to the compression ratio in the engine. Im pretty sure im not completly wrong but i'd wait to see what some other people say first.

regular any thing else is a waste of money. unless your turbo hehe

I've read that unless your car calls for premium, using it isn't a good idea. Having an h22, I have to use premium. But, that's a sacrifice I'm willing to make. Even tho it's almost 3.50 a gallon here

really? One of these again? we just went through a batch of these threads

Higher octane fuel in your stock cb7 won't do anything but waste your money. It won't hurt anything either, it'll just waste your money.

If you have a higher compression engine (be it N/A or FI) you will need higher octane to reduce knocking.

Putting higher octane into your car won't increase mpg's, hp, or torque.

The Higher the Octane the hotter your car runs..... So keep it low 87 all the way!PeAcE

FALSE- higher octane will not make you run hotter.

Using higher octane fuel in an engine that doesn't actually require it (i.e. NA with lowish CR) will very likely result in a small but measurable deterioration in economy, torque, and power output.

93 ftw better performance burn less gas when gas price gets high like $3 to $4 gal go with 89

Beat me to it...

unless you're running high-compression pistons, high octane gas is a waste. higher octane is less resistant to detonation, hence using it with high compression pistons. it takes slightly longer for the piston to reach it's peak so you need a gas that won't detonate too soon

stick to 87 or at least don't go over 89

lmaooo not for nothin but im runnin airplane gas on my cb7 now...omg u should see it run.......

heck ya dude!! the higher tha better. only if i cAN get my hands on some alien space ship fuel, my cb7 will fly

lol nah really tho im runnin on airplane gas....its like runnin nos on da car
