How much Sea Foam in a motorhome that hasn’t been started for a couple years? [SOLVED]
We have a motor home that hasn’t been started for a couple of years. It has 50 gal of gas. What and how much should be added to the old gas? Its a Ford V10.
Good question! Your goal with an engine that’s been sitting like that is to clean up any gum or varnish that formed in the fuel system while it was sitting. If the fuel in the tank is only a couple years old, the motorhome should start and run fine. You’ll want to run through as much of the old fuel as possible.
Then, add 10 gallons of fresh fuel and two 16 oz cans of Sea Foam Motor Treatment (or better yet, High Mileage, which is a strong cleaner). Drive until almost empty, and then refill with fresh fuel. The higher concentration of Sea Foam will do a good job cleaning up the fuel system.
