Exactly. If you have a severe need to get rid of some money I can be of assistance.KoreanBoi said:You'll be wasting money, that's what will happen :3_puhbye:
91 octane or whatever grade premium gas you get is designed to ignite at higher temperature, and in an engine that only requires a 87 octane regular grade gas, it won't do anything other than hurting performance.
JDOGG said:3 things to consider here.
Premium gasoline usually comes with more additives to keep your injector's and such clean. this may help keep everything running well and keep performance at it's stock max potential.
Also, I've read somewhere... in an article on octane boosters...that higher octane fuel takes more to knock...but once it is ignited it burns faster. this has the effect of advancing the ignition timing on your car. I personally have noticed better gas milage with premium fuel. it is however possibly my imagination as i dont measure these things regularly.
Lastly, with our relitivly high compression ratio, it is unlikely that our ignition timing is advanced as fully as it possibly could be. this means premium fuel could silence the evil knock sensor and help stop the ecu from retarding the ignition timing as it normally would.
All of the above would lead to slightly better perfomance. reguardless a CAI would dominate the gains made by premium fuel and its a one time $150 shot vs an extra 10-15 cents per liter (up here in cananananada) every time you fill up.
You will gain zero performance from running higher octane fuel than required in your car. The only reason to user higher octane fuel is if you have a modified engine (higher compression, forced induction, etc). If the car calls for 87, using higher octane fuel only costs you more money. You gan no higher performance.Using high test does burn cleaner like somebody said earlier, so in the long run it's better for your engine. And you get slightly better performance.
You dont gain much performance but theyre is a little, theoreticly. The reason high test gasoline has better knock resistance is because it has longer chains of hydrocarbons. once ignited, these longer chains actually burn faster than the shorter chains in low grade gas. Every car on the planet comes with slightly retarded timing from the factory for no other reason than for safety. retarded timing + gasoline that burns faster once ignited = a more fully burnt air fuel mixture at TDC. the fully burnt mixture creates more pressure on the piston, this in turn creates a little more power.You will gain zero performance from running higher octane fuel than required in your car.

The statement above is 100% correct... AND a higher octane fuel can, in some cases, assist in leaving less of a carbon build up. However, a tank full every so often is all that is needed. Your tibby is most likely not leaving a huge carbon buildup anyway.. Regular fill ups with 91-93 is a waste.You will gain zero performance from running higher octane fuel than required in your car.
LOL! Maybe Gamz should start a new contest for most annoying NT.com member. I'd probably win that.Not this again NOVA... LOL
