I do mobil. Their is a place called Sunco or sumthing around here that sell 100+ octane for like 5.99 /gal. haha

 

I would have to go with 76, why? Because its the official gas of Nascar. I know its not the same gas as Nascar, but if Nascar is using 76 gas. I am too.

 

Aren't you afraid that your car will only be able to turn left?

 

76 or Shell...

 

I've been running a mix of Union 76 (Tosco) 91 octane premium with ethanol and their 100 octane racing gasoline. On the dyno it is 15 to 20 hp above what was expected. Who said there is no advantage to racing gas? Makes the car run like a banshee.

Here in CA, the forumula for premium unleaded (all we get is lousy 91 octane) is exactly the same.

 

I only get 76

 

Cheveron since day one

 

76 because it is the only fuel that gives me more daily mileage on my Lexus RX300. I can not tell if there is more power but the average mileage per gallon goes from 16.9 to 18 miles per gallon.
That is what the computer tells me :-)

 

Chevron, and ONLY Chevron.
