Poahl: What grade gasoline do you buy?

[freebee]

Always regular. Its pointless to put in the higher grades. Most engines have anti-knock capability, doesn't "hurt" the engine to run on regular. For optimal performance, many engine can take advantage of higher octanes, but for everyday low-load, level grade city driving, not necessary.

Excuse me?

My car manual recommends the 87 octane. That is what I use.

Everyday load for me is at least 10-12 WOT experiences.

it isn't worth the extra 20 cents

 

[Insane3D]

Mobil Premium (93).

My aftermarket aluminum heads require it since they raise the compression from stock.

 

[DuBobD]

I run Sunoco 94 in my GTP. The higher, the better. 93 minimum for me.

that's true, but then it retards your timing when you try to gun that sht =P

91, prelude, engine asks for it

 

[Actaeon]

Usually 87. I bumped up the Timing, and I'm debating moving to 89 Octane to prevent pinging. I don't think its occuring with 87, but I'm not sure yet.

 

[Aharami]

93

 

[Brutuskend]

It depends on which car I'm driving.

Truck. Regular.

VW. Highest octane I can find, sometimes with octane booster.

VW is NOT stock.

Fixed. If you really need that much boom, make your own and at least know the strength of it.

[PoPPeR]

california premium 91

 

[ThePresence]

93. It's the only gas I've ever put in my car. I have no idea why, I just assume that it's better somehow.

 

[LordMorpheus]

haha, why put anything but the cheapest in a car worth around eight hundred dollars?

 

[Shawn]

93. Gotta use it or kaboom.

If the engine is supercharged (which includes turbos), you could blow a piston by running regular. You seem to be very misinformed on this subject. Anti-knock capability simply involves altering the ignition timing. To improve fuel efficiency, new cars with OBD will advance the timing as far as possible -- until it senses knock -- then retard slightly. That's all "anti-knock" is for.
With a supercharger under boost and in lean conditions with insufficient octane fuel, knocking can occur from pre-detonation prior to spark ignition. Can you say boom?
Oh well, it's your motor.

If your owners manuals says to run regular, then always run regular. You won't gain anything from running premium. If your owners manual says to run premium, then always run premium. But the only thing you gain is not blowing your engine.

My car has a turbo. I run premium, always. Which in my state is 92 octane.
