You’ll note the severe scoring and wear on the camshaft bearing caps on the Audi/VW 1.8 liter turbo engine. Audi and VW strongly recommend, and in some cases require the use of a full synthetic engine oil in their cars. No where is this more important than in the engine which use a turbocharger. Non-synthetic, or low quality engine oils will break down under the load, carbonize, and cause internal engine damage or turbocharger failure. This is why we always suggest the use of a full synthetic engine oil in model years 1999 or new. The oil does cost more, but does not have to be replaced as frequently, and the protection offered to your
engine is priceless.
