[quote=Anonymous][quote=Anonymous]The protections that oil provides to your engine degrade over time. This is why they recommend changing after X miles or Y months. You should go ahead and get it changed.[/quote] That’s a function of time spent in a *running* engine. Not an infrequently used car. As the engine runs, the oil picks up contaminants from fuel combustion, and additives and friction modifiers in the oil vaporize and are gradually “cooked out” of the oil as it is heated over time. But oil sitting day after day in a cold engine in a car that is only driven a few times a month isn’t “aging”. It’s not doing anything. Oil only degrades during the time the engine is actually running. I have a Corvette that only gets driven maybe 1,500 miles a year. The last oil change it had was in 2018. The oil currently in the engine from that change still looks like brand new oil at 2,700 miles. Changing it unnecessarily is a waste of money and resources. [/quote]
