GotQuestions? Lubricants

Q. Will it hurt my engine if I don't use the same brand of oil every time?

A. No, the engine does not develop an affinity for one oil or have a negative reaction to changing brands. The engine just needs oil but, I believe this idea developed over time as a result of perception and the thought there were negative reactions such as increased oil consumption or loss of oil pressure as a result. Arguably, there can be some temporary symptoms if you are using oil analysis that have shown some increases in some elements typically source to the oil cooler, but even those harmless conditions are usually temporary and not engine wear related.
