Fuel stabilizers are essential and can prevent water formation within the fuel system.
More About Ethanol
The story above explains in easy to understand words what you need to know about ethanol, but let me go one step further speaking from experience: if you are going to use gasoline with the ethanol mix in your older engines having cast iron carburetors, galvanized fuel tanks, fiberglass tanks, rubber diaphragm fuel pumps, then treat the gasoline with Star Tron gasoline additive for ethanol. If you plan on running the engine regularly to use up all the gasoline that’s perfect. If the engine will sit for periods of time longer than two weeks then the carburetor, fuel pump, fuel tank should be drained. Star Tron is a wonderful product but it can’t keep the gasoline bonded to the ethanol for long periods of time, like winter storage. No product made yet can do this. The alcohol will rot the rubber, it attracts moisture, it will attack certain types of plastic and fiberglass tanks, the moisture it attracts will help to start forming rust on metal surfaces. Another good practice is to use Marvel mystery oil in every tank of gas. Every bottle of oil has directions on it for proper use.’
What You Need To Know About Your Oil
The secret to maintaining any vintage car or classic boat in Michigan is reliable oil. When it comes to antique boats, choosing the right lubrication is critically important. Northwood Boatworks recommends oil with higher levels of zinc and phosphorous (ZDDP or ZDP)—specifically Brad Penn Grade High Performance Oil. These additives help to prevent internal friction in older engines and those that have recently been rebuilt. They’re the first line of defense against heat and friction in the critical valve train components in these early engines.
