Marvell's mystery oil works great & a pint cost a couple of bucks at any hardware store. Automatic transmission fluid works as well. Always run the car out of fuel the last tank of the day, put a few drops of oil in & turn the motor over a few times. For long term storage (over the winter) clean the motor with motor spray & add about 15-20 drops of oil & put the whole motor in a zip-lock bag with all the air sucked out. (I aslo save those little moisture desicator packs that come in almost every thing electronic that we buy. Throw one of those in the zip-lock with the motor to attract any moisture still in the bag.)
