What Octane Do You Feed Your LT1?

What do you give your LT1?

Special treatment? How come?

Don't give it the good stuff? Why not?

Looking for reasons and a healthy discussion.

93 or 94, 94 when the Towel heads stop twisting Uncle Sam's arm so hard. I guess I'll vote for 94 since you dont have 93.

Hrm........guess I should have put 93.
94 is more readily available in my area so that's what I flew with...

This summer I may see how she runs with 87 or 89 because of the damn prices.

It depends on elevation... you go up to colorado and you get 84-85 for regular and 90-91 for premium.

Should say reg, plus. premium, more...

I run 93 always... 11.7:1 need it.

Re: What Octane Do You Feed Your LT1?

So what can I expect from running 87 octane?

Risk of detonation, which if sensed will cause the car to pull timing resulting in less power, and possibly less gas milage. However, depending on conditions, you may not experience any negatives at all....

I always run premium though.. I dont want to run any risks.

Re: What Octane Do You Feed Your LT1?

I run 90. Mostly because I can get it for the same price as regular

92 is our highest around here...that's what I always run. When I'm spraying I'll mix in 5gal of 110.

Re: What Octane Do You Feed Your LT1?

I put 89 in the first time I drove my car after purchasing it. The next fill I put 93 in the tank and it seemed a little slower. Has anyone else had this situation or was it just a crappy brand of gas?
