The HO runs best on recommended mid grade gas or 97. With gas going up daily and projected for a maybe five bucks by end of summer or sooner I’d sooner **** in the tank.
Anyone else running reg. grade gas in a HO? If-so what’s your opinion? The HO was really never worth the sixteen-hundred bucks on the sticker. The performance is crap and my wife’s six cylinder Saturn can eat it alive no mater what gas I pay to put in it. So at this point until I dump the Dak in the summer I thinking of running reg in it.

 

if your dumping it, the it does not matter what you run in it. : )

 

you probably wont notice the ho cams fully untill you start modding.

 

I run 87 when it's below 40 degrees outside, midgrade up to about 80 degrees, and premium when it's really hot outside. The premium makes a huge difference when it's hot outside, but there is no difference when it's cold.

And your V6 Saturn uses a Honda sourced 4-valve, quad cam, VTEC motor. It should be fast.

 

i run 87 in it when im running low on money. the computer will correct the differant fuel grade so there should be no issues

 

All that happens with a lower octane is there will be some knock retard on the timing. For every degree of knock retard though, it will cost you about 10rwhp according to some google searches.

Ive noticed with mine, on the Superchips performance tune and 93 octane, every once in a while during a WOT run I will get 1-2 degrees of knock retard. It is a good thing though because it will make it so pre-detonation cant damage your engine from prolonged pinging. If youre not concerned about squeezing all the power possible out of your HO engine, run the cheap stuff.
