Having three generations of vettes I find Sunoco works well in all three of the vehicles, I also find that Pioneer works well to. With the 59 I use a Medium octane and find it works very good. The 59 is a stock vehicle 283 four barrel 230 hp.The 64 I use the highest octane I can get from either company, and then sometimes I will add some booster to it. It is stock also 327/365hp (a bit more after resto.) The 75 I use medium octane, got to remember that was a low year for horse power. It has the 350/205hp. Out of the three vettes they all worked very good with the 59 and 75 using med. octane and as I said before the 64 using the highest octane. So what do you find works best for you?;)

Wow! You can use cheap gas! My compress is almost 11 to 1. So, I run 91 at the least or higher. It's nice to come across 93 octane in the summer.

:cool:

Med. octane here is around 89-90
High octane from Sunoco is 94 , Pioneer is 93 My 64 is running the same compression as your car is. The 59 and 75 are not high compression vehicles. So I guess we will just have to bring on the summer for you. Patrick up in this neck of the woods there is no such thing as cheap gas. :cool:

Stingray, it breaks my heart to look at gas prices, so I just put in the debit card and fill it up. :D

Sunoco 94 or Pioneer 93 works great on my 2002
Airwilf I found that in most cases either gas works fine. It's when you get into this monster motors they probable have a little trouble. Are you a member of the Stoney Creek Club or the Niagara Club? Don't matter, isn't this a great site. ;)

91 (the highest I think) Mobil here. Never tried anything lower in octane in either car.
Does Sunoco not carry Ultra 94 down there? Pioneer up here is a sponsor for the Quad C which a lot of the clubs belong to, so we try to purchase their product. But not being everywhere then I use Sunoco.
