And personally I am an advocate of starting and running engines up to operating temperature every few weeks and driving cars until fully warmed up regularly. I must assume that everything that can get gummed up, i.e., rings, chain tensioners, chain links, roller followers, etc., is apt to get gummed up sitting unused regardless of the quality of the oil. My conclusion was that the stuck valves on lawn mower engines that sit unused all winter would be just as likely with synthetic oil as with dino oil and automotive engines that sit unused for long periods shouldn’t have periotic maintenance extended due to the improved performance of synthetics. The next year the actions were just as gummed up as they usually were. A few years ago as I again found several actions sticking I left the Hoppes on the shelf and used some synthetic oil that was handy. At least once a year I pull them out to clean and lube them. Just as good personal hygiene dictates daily changes of your underwear, good engine hygiene dictates much more frequent oil changes than you are contemplating.įWIW I have a few firearms that just sit in a large gun case. Would you wear the same underwear for several days, simply because it “looked clean”? Simply “looking clean” is not an accurate indicator of how contaminated or acidic that oil may have become because of the short trips and infrequent oil changes.

When you don’t evaporate all of that water condensation, it turns acidic over time, and leads to deposits of damaging sludge in the engine.Īll of that being said, I would recommend that you not go longer than one year before you change the oil.

If you want to “exercise” the engine, you need to get the engine up to full operating temperature and then to drive for over 30 minutes in order to evaporate all of the accumulated water condensation that has been deposited in the motor oil as a result of all of those short trips. Just pretend its dino oil and change accordingly. Better at Higher Temperatures: Synthetic oil lasts longer than conventional oil because it doesn’t become as thick when exposed to extreme heat. That is actually the worst thing that you can do to your engine, as well as to your exhaust system. Longer Oil Change Interval: Some vehicles that require synthetic oil can wait up to 15,000 miles before an oil change because of the refined properties of the oil. I do take it a few miles a couple times a week to exercise the engine
