i was reading Aug05 issue of car and driver and thought this was informative for us EVO drivers.

 

ok i dont have any of those in my state, now what? i believe the best gas that i have in ny is sonoco gas. now there is one there that says conoco, maybe its just a spelling error. hopefully

 

sunoco is not conoco.

 

also bear in mind this does not mean that getting this particular brand of gas will give your car any more resistance to knock than the cheapo gas at the pump down the street. This jsut means that they have the detergents specified, and probably burn cleaner. Doesnt necessarily it's the best gas.

 

well let it be known that i had my car dynoed the other day and i had a full tank of mobile 1 s h i t gas and it showed. i was pissed.

 

i get gas at the cheapest place in town, cowboys and their gas is more than perfect.

if the octane rating of a gas is wrong at a station, i think there are some penalties they may be facing.

 

hey evildylan i have been meaning to ask you, where would you go about buying unleaded race gas in our area?

 

vrrrm, i used to buy my unleaded at R & R on meridian street. they have 104 unleaded. but now i only buy the leaded 114.

 

awesome.......ive thought about running leaded at the track, but worried about o2 sensors



sorry for thread hijacking

 

Agree 100%. In fact I saw this episode on the Discovery Channel about refineries and how gasoline is processed. The conclusion was gas is gas. The only difference was the detergent that they put before it gets to the pumps. All companies has a minimum standard that is set. So if a certain company put more additives than is required, they become part of the "top teir" gas.

 

true, i agree also, my wording wasnt there. so i edited the heading.

 

What about Mobil. Though they were the best.

 

I have Chevron, Shell, and 76 all near by. YES! But 76 had some problems with their fuel recently so I steer away from them sometimes.

 

i have always felt BP (amoco fuels) was the best gas, but its not even listed

 

Mobil for me.....
