Conventional versus Synthetic Oils

All turbo Saabs should be given synthetic oil and regular oil changes. Most recommend that synthetic oil be changed at least twice per year or approximately every 7500 miles.

Changing from Conventional to Synthetic

Some say that switching from conventional oil to synthetic, particularly on high mileage engines, can cause an engine to leak. What is actually happening is that conventional oil creates build-up around seals that would normally be leaking. Synthetic removes this build-up and can begin to seep past seals. So what is actually happening is that synthetic oil is uncovering the leaky seals that already exist in the engine.

Engine Break-in

Conventional oils are recommended for approximately the first 1000 miles during break-in of a new or rebuilt engine. The ultra slippery nature of synthetic oils can cause the rings to fail to seat properly, or take much longer than it should.

Recommended Oils

While the oils below should be up to date, it is important to remember that oil formulations do change, and oils that have previously been adequate may no longer be.
