1966 GT350 source for leaded fuel.
« on: March 07, 2022, 11:05:16 PM »
As a new owner of a 1966 GT350 can someone suggest a source for hi octane leaded fuel? I am located in the SF South Bay. Thanks.

Octane Supreme octane booster with lead is what I use . http://www.wildbillscorvette.com/octanesupreme01.htm . I have used it successfully for years.  It is used to doctor your gas to various octane levels based on what mixture of the product and the gas you start with . It is more convenient and comparable in price to race fuel when mixing with your gas but with a lot less hassle. At least to my perspective.

Congratulations on ownership. Many factors come into play for different engine combinations, most of the time over the last 55 years the valve guides have been changed out so you wont need leaded gas for your car. So now comes the need for higher octane to eliminate the dreaded pinging or rattling. Most vintage engines run in the 10 to 1 ratio so if you run premium gas with some auto part BOOSTER you should be good to go, if you run higher compression ratio you might need to run a mixture of race gas and regular pump gas. Your specific tune will dictate what your engine likes best, race gas is running around 17.50 to 19.00 dollars a gallon now, my cars get to play for 180.00 for around half an hour on HIGH TEST. A little experimenting will go along way on finding that sweet spot. ;)

If you are into DIY, check into numerous Youtube videos on how to decant the ethanol from fuel. You will lose a small amount of octane during the process, but can easily be remedied with a small amount of octane booster.

Fortunately my area has 93 non ethanol so not an issue.


@427heavan, Yikes where are you buying race gas for those prices! I just bought 110 at Sebring Raceway for $11.50/gal. I hope I don't see those higher prices... but our POTUS seems inclined.

100 Low Lead at the local airport. You'll probably have to use 5 gallon cans since a lot of them will balk about putting it in a car (unless it's an obvious race car on a trailer). Airports are harder to get on/in since 9-11. Go on a Saturday morning and get breakfast start a conversation re: needing gas for your classic car and someone will help you out.

Hi Rich,
I’m inclined to go with the VP fuel, but where can you purchase this product in or around the SF Bay Area? Thanks.

Here's VP fuels master list of different fuels. Be prepared to pay upwards of $78 for a five gallon can, before tax etc. The second link is a dealer search engine to help locate a dealer near you. Just a FYI, Sunoco fuels is another option rather than VP.

I am a left coaster so he can expect 90 dollars a 5 gallon can. I just spoke to some friends around the country and 90 dollars is about the norm for it, for high compression engines. For street stuff they make many alternatives around 15.00 gallon that might be a place to start. Best of luck to get the formula right! ;)
