Fuel Octane, 87-93 what do you run and why?

91 always. Talks back otherwise

 

On the ranch I use a 1997 Z71. Only gasoline ever used in it has been 87 without alcohol. 300,000 miles and still runs like a top. I call her my little bitch-hog.

Mods: Edelbrock headers, Holly glasspacks, straight pipes. The cattle dig the pasture-pounding sound.

 

I put 93 in it one time just cause and I swear the taco tick was faster...

 

Avoid Sunoco Ultra 94 because it contains ethanol.

 

91 because boost!!

 

91 because that's what it has always had put in it and I guess I like to waste money.

 

87, because I can. I have to run high grade in my Camaro and filling a tank getting as few mpg's as it does kills me. The Taco may loose a little performance but I don't care.

 

I run 87, but im reading up on the eco fuel/ alcohol fuel for cars and trucks. Has anyone used alternate fuel on their taco

 

You'll need to change out your lines and your pump to run anything above 10% Ethanol. Ethanol breaks down standard fuel lines and is rough on the pump, injectors, and anything else in the fuel system. Not to mention our trucks have no tune for E85, which really limits what the engine can do with that fuel without a tuner. With a tuner the extremely high octane rating of Ethanol can make some impressive numbers power wise but the fuel economy will suck due to it's lower energy per liter.

 

Am I the only loser without a s/c? Haha

Oh, and 87. It's a truck, dont care about mpg.

 

91 cause SC and no ethanol
