I stopped at a station that had some a few months ago but the $7+ dollar/gallon price tag changed my mind pretty quick. I went with the 93 instead. Compared to the 91 standard here in OK that I usually run I might have felt a slight performance increase. Maybe if I autoX this summer I'll try the 101.

There's a station on the water at the lake I go to that has 110 for all the racing catamerans. Maybe I should try some if that. I think it might contain lead though.

I doubt the computer will adjust timing to a noticable degree to improve your performance with that high of an octane. Unless you have maps to adapt to those octane levels it is a waste of money. I do run 93 since that is what high octane is here. The Viper is mapped to it and does make a difference. The G, doubt it cares if it is 91 or 93.

I can't recall the specific detail but I do recall that more harm can come from running that high of an octane (100+) in a "normal" car. May have been a lack of proper fuel burn since the car does not have a high enough compression ratio.

Doesn't the G have an 11:1 compression ratio though? Is that not high enough?

Don't put too much in, Theres a station that sells 100 near me for 7.80 and sometimes I'll put 3-4 gallons in. The nice thing is you can smell the race gas burning. Its good for cleaning out the injectors too.

That compression ratio is why you run premium. My primary point is that most cars are not designed to advance the timing to take advantage of a higher octane fuel. They can retard timing to run on lower octane to prevent knocking. But I doubt they reverse this. Also, I believe higher octane has a different burn rate which again could cause your car problems in the long run.

I am sure a quick google search will provide more expert information, I am mostly going from memory. And I am sure my opinion is an over simplification of the issue. Regardless, it is a waste of money to run over 91/93 octane. It may be "fun" but it is costly.

^^bc it burns the higher octane fuel, basically an injector cleaner is an octane booster, aka racing gas is higher in octane.

The station by me that has the 93 and 101 is unleaded. The boat dock at my lake has 110 that i think might be leaded. I was just joking about that. It is intended for all the racing cats that have 1000+hp racing engines in them.
