Semi-Synthetic Motor Oil Overview

Semi-synthetic motor oil has a unique composition that blends conventional and full-synthetic oils' features, explaining why this motor oil is also called synthetic blend. The additional synthetic base stock makes semi-synthetic oil's viscosity thinner than conventional but not as thin as full-synthetic. The additional additives make semi-synthetic oil's resistance to thermal breakdown better than conventional but not as good as full-synthetic. Blending conventional and full-synthetic also increases the price of semi-synthetic above conventional but lower than full-synthetic. The improved performance beyond conventional and lower price than full-synthetic make semi-synthetic motor oil a popular option for those wanting advanced lubrication and engine protection without paying the premium price of full-synthetic.

About Switching from Conventional to Semi-Synthetic

Volkswagen owners whose engines have accumulated higher miles often switch from conventional to semi-synthetic for improved viscosity, internal component protection, and extended engine life. Although the higher-mileage threshold is not mandated, the commonly accepted automotive industry rule-of-thumb is 75,000 miles. If your Volkswagen's engine is lubricated with conventional oil and is approaching or beyond 75,000 miles, we invite you to discuss switching to semi-synthetic motor oil.
