WOW! That's nice!  Can you even drive one of those older Caddy's with the high compression on the premium they sell these days?

[guidematic]

I do mine.....I run it on Sunoco Ultra 94.

They were only 10-1. What's the big deal?

[guidematic]

Up to '69 they were 10.5:1 Those funny pistons in the '70 brought it down to 10.0:1.

BTW, the LT1 in the '94 runs 10.3:1, it requires 91 octane.

Those GTO motors can be 13-15to1 but it takes computor control for timing retard and spark control!
I will stick with whats proven!GT0 only was made for what a year,computers are cool but not for valid
transportation!

[guidematic]

GTO? As in current race engines? Yes I have heard that some race engine run near diesel CR's. NASCAR at least was running 14:1 and higher back in the 90's, but no computor control, just MSD boxes.

However they have access to race fuel with crazy octane numbers. As high as 112.

How did a GTO come into this?

I run 87 octane in mine. It made no difference when I switched from 91.
The reverse cooling allows it to run on regular.

It requires 91 for optimum performance. I have run 89 at times. But when any detonation is detected, timing is dialed back. That affects both performance and fuel economy.

No Pontiac GTO, or any Pontiac engine for that matter, ran anything close to those stratoshperic CR numbers. I think the highest I can recall may be in the 11.5:1 range for some of the high zoot Super Duty and Ram Air engines.

Mike

[EXCRUISERGUY]

I didn't notice any difference at all. It will still smoke the tires all the way down the street and get the same fuel economy. I couldn't justify paying an extra 10 cents a Liter.

Temperature has a lot to do with it. Run the AC on a hot day, and I'm sure you'll see some differance.

I know I can get away with 89 most times as well, and have been guilty of using it a fair bit in the last little while, but I have never used 87.

87 works very well in the '90 Brougham and '88 Eldo, though.

On a cool day with no AC, 91 works fine in the '70 Fleetwood as well. I bet if I gave the engine a good top end clean I could get away with it more often.
