Do some oils tend to have higher consumption than others?
Consumption of thin oil is greater than that of thick oil. This is a general rule, but sometimes there are exceptions. For example, when changing the oil grade, consumption may be higher before the first oil change, and a new engine often consumes more oil than normal whilst running in. All in all, the engine should consume some oil, although it is lubricated to a sufficient degree by a very small amount of high-quality motor oil.
