Before I put away my little diesel for this coming winter--it's my first diesel, and I had only heard horror stories about gelling fuel and the like--I asked parts managers at two tractor dealers, and both suggested putting a conditioner in the fuel. This prevents diesel fuel from gelling and clogging up the system. Gasoline won't gel, but it can get pretty stale after a few months. Air space might contribute to this (my guess). My suggestion is to fill up the tanks as far as possible on the tractors you're not going to run, to keep the moisture in the air from condensing and adding to the rust inside the tank. Aside: I've had a couple of small motors that I shut off with fuel in the carbs, didn't use them for a year, and found that the old fuel had made a mess of the jets in the tiny carbs. I would shut the engines off with the fuel valve on a gas motor (but NOT on a diesel--you don't want air in the system, or you'll have to bleed everything before you start again). This way, there won't be any unburned fuel to dilute the oil, and especially to wash oil off the cylinder walls. I don't know if it's a good idea to keep fuel in the carburetor just to keep the gaskets from drying out. ANYBODY out there know? I "discovered" gun oil a couple of years ago. It's light, comes in a spray can with a straw, and is great for putting a little oil in each cylinder by removing the plugs. Could help a little with the rust that is probably inevitable if an engine sits for months. The cylinders with open valves are probably going to get a little moisture from the air. If it's not a lot of trouble, it wouldn't be a bad idea to turn the motor with the crank (up on compression would close both valves, and you could do this round-robin with the other cylinders as it occured to you). Some people here have suggested a can to cover the exhaust pipe, and maybe that could have the same effect. After all this, I'll have to say that when I was growing up, we just parked 'em and forgot about 'em until spring. If there was any rust or other damage, nobody knew it.
