Dang With the S/C you HAVE to use Premium period. TRD even supplies a sticker that says Premium Fuel Only.

The AvGas situation.. dont use it..

Go to Bandimere and get some Sunoco Race Fuel Be prepared to drop $3-4 a gallon. There is another place in Wheat Ridge that sells 110 but if any of the people are up on their game, you will not be able to pump it into the truck directly. All of your "race" fuels are for off road vehicles, meaning race type vehicles and by law are not to be dispensed into normal on street vehicles. With that said most places will sell it to you no matter what. Just be prepared for nothing. Higher octane does not create horsepower, just as we S/C truck owners have knock with low octane fuel, race vehicles with HIGH compression (11, 12, even 14:1) have knock with lower graded fuel.

We sell 110 octane to the ricers and they think it is magic, but it actually has a reverse effect and causes the car to run worse, ie incomplete burn.

I have access to the higher graded fuels and even with my discount it is outrageous to even think about filling up at that price. I have the $$ for the URD kit but have not found any info on tuning in the denver area. Like your truck mine only knocks up hill under load.

Best bet is to spend the dough and get the URD kit, in the meantime .. Do the Seafoam treatment and keep your foot out of it.

 

travelinman- sent you a PM.

I don't think the place in Wheat Ridge sells 100 octane any more. I drove past there a couple weeks ago and it looked like the place was being torn down or remodeled.

 

i thought diesel was super low octane thats why it explodes without a spark and thats also why it would be cheaper. why would super high octane gas be less expensive than regular old 87 octane?

 

its more expensive than 87 octane here. If it is cheaper, its because its less refined than gasoline. Besides, you can't really compare high octane gasoline to diesel because its just not the same. Gasoline is more refined and has more added chemicals than diesel does. http://auto.howstuffworks.com/question90.htm

 

Diesel is not very far removed from heating oil, so its price usually goes up in the winter since more of the raw materials for it end up heating homes. In the warmer months it is usually cheaper than gasoline.
