Oil Additives

Most people generally think about fuel additives, but oil additives are just as important. A good engine oil treatment can save you heaps of money if anything gets into the system that shouldn't.

An oil additive like Wynn's Engine Stop Leak will assist in restoring the pressure of the oil and also its compression. You can stop an oil leak in its tracks, and prevent future leaks, without having to dismantle the engine. Engine oil additives not only help to revitalize the O-rings and the oil seal rings found inside the engine, but they can also reduce the amount of smoke put out by the exhaust due to reduces oil intake.

Diesel engine oil additives in particular won't damage the delicate catalytic converters and most are totally compatible with all types of oil, whether it be synthetic, mineral, multi-grade or single.

Check the instructions on the back of each product before performing an oil flush to make sure it's compatible with your vehicle.
