Will my sho run on 87 octane

[bigbadfords]

Hey guys, I just purchased a 96 sho and was wondering how these cars run if you put regular 87 octane gas in them??

I run mine on 87 just fine. When it gets really hot out (90+ degrees) I will put 89 or 92 in it as I notice some pinging when I get on the throttle.

I wouldn't. Especially in the summer. I would go to midgrade if I was feeling frugal.

I run 89 all the time, or 92 everyonce in awhile, never ran 87 in any of my SHO's

I only run 87. 89 E10 a couple times in winter to burn up any moisture in the tank.

Yes. Only 87. All the time.

Back in the day, the first three V8 SHOs to run in the 14s all did so on 87 octane (mine was the first).

If it doesn't like 87, it isn't running right.

I put 87 in mine for the 9 years that I've owned the car. I only put higher octane in it if I'm taking it to the track. But for the drag strip it gets 87.

Key point there from Ron. If it is not running just fine on 87 octane, something is wrong, and it might be worth looking into it.

I run 93, but with the $10 a month in gas I put in it, the savings are miniscule. Guess that tells you how much I drive my SHO.

 

[SHO.fast]

i only put 91 octane in my 90

93 octane in nearly all my vehicles. If I put a lower grade they tend to ping like crazy. Can't imagine why......

If you unplugged your fans that sit atop your intake, it might help with this issue.

Nah man, get it right. It's a "heat pump".

87 but I live at a high elevation and it's hard to find anything higher than 91 around here.

Less need for octane at higher elevations, anyway.

Sacramento is 21Ft msl and mine has lived on 87 for the last 5 years it is coming up on 225K this summer the temp got up to 108F and not a ping.

I guess my detonaniton sensor is doing it's job.:woo-hoo:
