which octane u use

FYI, the commonly used octanes in the USA are 87, 89, 91 and 93. Anything higher is usually considered race fuel...

 

Remeber also that your octane rating system is different than ours.

Euro: RON

USA: RON+MON/2

 

There are some people I know that use c16 (117 octane leaded) in their daily driven cars.

But as said majority between 87-93 depending on state.

 

That's just silly unless they are high-boost forced induction cars!

 

Some guys I know that use their 700+ hp blown/ turbo Vettes as daily drives. No cats.

 

91, all the time..and where available, 100. [good thing there's a place near my house that has 100 at the pump..when i'm there i'll usually mix in a few gals of 100 to bring the watered down CA gas to about 95]

 

What 100 running out your way, price wise?

 

I live two blocks or so from a 76 with 100
was at that gas station little over a week ago
Same price as always it seems
7.99 a gallon for 100
330 for regular 87

what a jump

 

Is that the one off La Paz? I remember 100 being around 5.50 two years ago.

 

Make sure your engine is tuned for it. Modern day engines advance and retard to prevent knock for a specified range (what we normally buy) so you'll probably want an ECU tune to take advantage of your 200000 octane gas.

 

yes sir
