I know the mileage side of this question has been talked to death. What do you guys think about oil change time interval? I have a number of older vehicles that sit in storage. I drive maybe 1500 miles a year on any of them some much less. I change the oil once a year before winter sets in and they sleep over the cold months. I haven’t had a problem yet but am I asking for trouble?
This question also goes for newer cars. Due to unforeseen reasons, my wife’s Dodge Magnum has 3200 miles on it in for almost a calendar year. It is full of the dealer synthetic blend, what ever that is. It will get changed tomorrow but how long is too long time wise?
I have heard of damage to bearings because of the acid in the oil. But what is the real reasons here?
