I have a beautifully restored 1940 Buick Road Master Convertible with a Straight 8. Being located in Michigan and Northwest Ohio it stays in storage from Oct to May. The fuel tank is filled and treated with Sta-Bil. Then we refil with fresh gas to start the season. Last year as I first drove it, it kept stalling out after 10 to 15 miles. I occasionally use the electric fuel pump when I suspect carb freeze but this did not help. I was constantly messing with the carburetor but I kept stalling out then having a nightmare to get it re started. Also the fuel gauge was not working and the restoration is less than 5 years old total and I mean total off the body restoration. I dropped the tank to check on the fuel level sensor and found the float corroded into two pieces at the brass solder junction. Then the fuel pump rubber diaphragm was also partly eaten away. Almost anything rubber in the fuel system was being corroded. I then found out from the experts in the classic car circles recognize that the ethanol in the unleaded gasoline is reeking havoc on the older classic engines. In fact word is out that the percent is being increased from around 10% to up to 40% in the near future. One can not obtain gasoline in Michigan or Ohio that has not had ethanol added to it. I have just found that Sta-Bil is now marketing Sta-Bil Ethanol Treatment additative. Has anyone had sufficient experience with this product to make comment or have other suggestions? I have been using some Aviation gas because it has no ethanol added but it is cumbersome to obtain when you are on the road and there are legal questions to boot.(Road tax, etc).
