Re: Winter storage
I'm a service rep for a US marine engine manufacturer, been doing it all my life. How to store a marine engine is critical to it's life.
As you can see from the posts, opinions vary largely here. These are some of my own.
1. I no longer recommend filling a gas tank before long term (more than a few weeks) storage. Fuel quality has gotten so bad these past few years that in spite of using a good fuel stabilizer your fuels octane and overall quality will be poor, at best, by the time spring rolls around. Then you start up your performance engine and run it on low grade fuel. Not good for piston life.
2. If your storage area is heated, you are among the lucky few. In a constant temp environment condensation will be less likely to form in your gas tank.
3. Periodic start-up is not a bad idea, but I don't believe it's a cure-all either.
a. better for engine and transmission gasket and seal life.
b. gives the starter, alt and any other accessories a little workout and a new resting spot.
a. Condensation in your exhaust. This will not dry out by letting the engine idle. No matter how long you let it run. The exhaust system needs good temp and good air flow to completely dry out.
b. You are starting your engine with little residual oil in the journals and on the piston skirts. A better idea might be to fog (run storage oil through the carb) one time once you put it away. This coats all the internals with a good rust preventative.
Personally, I feel that an oil change, some silicone spray on the engine and electrical system, air in the tires, and a lovingly applied coat of wax is the best thing prior to saying goodbye to your car for the winter months.
disconnect, or take the battery right out, charge it once or twice during the winter, and spend your time keeping the snowblower running....
I'd still put stabilizer in your gas tank but I do like to run it pretty dry in the fall.
