Default Octane

Hey im new to the forum, and i have a 1998 Bonneville SSE and im not sure what kinda of octane gas should i use in my car. Is 93 octane too much meant to take the high octane gas. ive used the cheap 88 octane and I wonder about it. So wat do you guys use?? ?

Also I bought NOS brand octane booster so if i was to race one of my friends and use 93 octane and then use this nos mix to boost the octane 6 points would my car blow holes in the gasguets???

If you are NA (the standard L36 3800 non supercharged), premium is not required. only Supercharged engines need premium.

In an normally aspirated car with a moderate compression ratio, 87 or 89 octane is perfecly fine. If you were to get into modding, then premium fuel would be recommended, especially due to the added spark advance with aftermarket computers.

for the record, octane booster raising octane 6 points, IS NOT going to make 89 into 95, it will make 89 into 89.6 Octane rating and "points" are two different things.

Excellent accurate advice here so far. I'll add that higher octane doesn't have more combustion power. It'* harder to ignite. In a supercharged engine, the static compression combined with the boost pressure raises effective compression significantly to the point that the fuel can pre-ignite. Higher octane will 'wait' longer for the spark. That'* why we use it in the L67'* (and have to) and why it won't gain an L36 anything unless that L36 is modified or has other problems.

There is no way any can of ANYTHING including nuclear waste will raise a full tank that much. Maybe if you added it to only one gallon of fuel, but not a whole tank.

I'd have to add about 4 gallons of Toluene to my tank to raise it 6 points. Don't waste your money. That'* a myth in a can.

One gallon of UNLEADED race gas won't raise your octane more than 1 full point either. Not when mixed with a full tank of pump gas. You have to do the math to calculate it. I've done plenty of mixing with 100 octane unleaded and Toluene. It takes careful math and mixing to get it right.

My bro and i did research on the (points) thing.

"10 Points" in there terms me 1 Oct rating

More then 1 brand all said that, one he called, another i just read like 10 bottles at advance one day lol

so 7 points would mean .7 oct you would gain. not much.

EDIT* Here is a website to help explain. http://www.dynotab.com/octane.htm
