SAAB 1994 AND LATER 4 CYLINDER ENGINES
These engines are building up alot of sludge in the oil pan area,causing the oil pick up to plug up. This is causing low or no oil pressure problems,resulting in turbo & severe engine damage.
Your best preventative maintenance is to change the engine oil every 3000 miles. If your saab has high mileage,we would suggest removing the oil pan and cleaning of the pick up.
