Add a can of marine fogging oil to your next online purchase. Starbrite, CRC, Stabil, Quicksilver, Mercury- any brand in an aerosol can with the red tube will work fine. I would not use bar oil !! But some engine oil would also work ok.
Fogging oil is a bit thinner, specifically designed for corrosion protection, and made to burn off. Besides my boat I also use it for lawn mowers, boat generator, home generator, chainsaw, pretty much anything with an engine.
