High Octane Fuel

Dunno what FBH tells you, but in my Euro-spec Mercedes I will do a mix of 100 octane unleaded and premium to bring the octane up, as the car will detonate particularly when its hot/AC is running. I get mine at the pump at the Unocal station right at the end of the 110/start of Arroyo Parkway in Pasadena. Mind you it is nearly $6.00 per gallon.

I haven't used it in my F-car yet but haven't (1) had the car very long and (2) needed to.

Here's links to SoCal locations, the main page, and the blending chart.

Cheers
Kevin

I have a 55 gallon drum of 104 unleaded sitting in my garage. They are excellent.

 

I mix 100 with Premium for my G.T.O. it comes out to around 95 Octane. There is a 76 station on San Miguel in Newport Beach.

 

There is also a 76 car wash at LaPaz and the 5 that sells 100. A 25% mix is good for ~20rwhp in the F40.
California Gas in general is not too good. If you have over 10-1 Compression ratio I would mix 10-20% in on a regular basis. Every 2 or 3 tank fulls will make a difference.
A friend of mine used some in his M3 and noticed a smoother running engine with more power. Try it for yourself and see.

FBH Service advised me of the same thing for my maserati. They said the 91 is the way to go. They had a 550 with, i believe, injector problems due to hi octane use.
