For many years we bought and used Amoco White Gas, which supposedly had no lead. I ran it in many cars without a problem, but never could understand that if fuel without lead causes valve seat problems, how did we survive using the Amoco White Gas? It was a premium grade and a little more expensive than other brands as I can recall.
In NE Ohio it is no longer necessary to post Ethanol content on the pumps (at least I don't see any such information). They publish lists on the Internet of Ethanol Free Gas Stations and one is about 1/2 mile from my home. I asked the manager if their fuel contained Ethanol and received a definite "Yes". Others claim that premium fuel contains no Ethanol, but other information posted on this and other forums say otherwise. Either way, the Ethanol destroys rubber hoses and components in our older cars, as they were not designed for this type of fuel. We have a car museum and have been gradually replacing all rubber fuel hoses with SAE 30R9 fuel injection hose, which is recommended for Ethanol fuel. There are also rubber components in fuel pumps and carburetors, so we have a long way to go.
Here is a quote from another forum. Google "Amoco White Gas" for more information.
"Back in the '60s, when most gas was leaded, Amoco had this special super premium which was not leaded and was therefore safe for some uses where leaded was not, and it also was much less likely to foul plugs in motors which had a severe plug fouling problem, such as the early Porsche 911 (I had a late '66 for a while in the '70s) and Ferrari V12 motors of the pre-smog control era, so it was much sought after by owners of high-performance machinery, including modified American "super" cars. I doubt that it would be any different from the current 93 octane unleaded in practical applications, if it were still on the market, except that some of the other additives that Amoco used instead of lead have now been banned, too.
Addendum: Amoco's early unleaded premium is NOT the same as the "white gas" meant for lanterns, camp stoves, and torches, which was a form of light distillate, similar to the cheap fuel sold for specially equipped farm tractors during the Depression and WWII years. It was almost as dangerous to use the Amoco premium for those purposes as any other gasoline because of the explosion danger and the other additives. "
