Synthetic oil can be used to extend oil changes in any engine. That is its primary benefit. Our shop uses synthetic blend oil in our regular oil-changes. If a customer has an oil consumption problem and must add between changes, we suggest regular non-synthetic oil, just as a cost savings. Full synthetic, synthetic blend and natural oil are all compatible and in a pinch, it is much better to mix types of oil when adding than to
allow the engine to run low on oil while you search for the right type!
