That's a better idea than cranking without starting on purpose. Oil may pump, but not much. Running it for a minimum of 7-10 minutes for at least something of a warm-up cycle is good for the engine, and a drive around the block, even better (partly so you can take note of other things that could be caught early, like a slightly low tire, and party to burn fuel, so you can keep putting fresh fuel in the tank). Also, if you let the car sit a long while, it's better to have the tank FULL or EMPTY, rather than half-way. With small equipment, it's easier just to keep it empty. For the 124, I'd suggest keeping the tank full. It leaves less room for water to enter and condense as temps change.How about just start it and run it occasionally?
