2 Years Without Changing Oil?

Change the oil after Christmas every year and run non ethanol fuel.

It's also a good idea to keep the fuel tank full to prevent rust.

While vehicles manufactured several decades ago had mild steel tanks, these days the tanks are either plastic or stainless. There's nothing to rust.

Also, there's always headspace in the tank - you can fill it all you want, but there's a few inches of air above that fuel to provide for expansion.

When I replaced the fuel pump in our 2000 Four Winds on E-350 chassis, the tank was all stainless, and the filler inlet had an internal pipe that turned down into the tank. While the fill capacity was 55 gallons, I'd bet one could put 70 to 80 gallons in it from the fuel pump opening to completely fill the tank.

Your comments reminded me of something: When filling up my E450 based Class C motorhome's gas tank, the station pumps always stop too soon. If I baby the fuel nozzle trigger very carefully and take another 5-7 minutes, I can trickle another 5-6 gallons into the "55" gallon fuel tank.

Now I wonder - when I'm doing this - if I'm merely getting a true 55 gallons into the tank ... or more than 55 gallons?

Sounds like foaming diesel. Not uncommon. If gasoline, you run the risk of overflow getting into the evap system and killing it prematurely.
