Q: What is semi-synthetic oil?
A: Semi-synthetic oil is a blend of mineral and synthetic oil. The ratio of the mixture typically ranges between 35/65 and 25/75 of mineral and synthetic oil respectively. It is definitely better than regular motor oil but is still inferior to going full synthetic.
Q: When did synthetic oil become popular?
A: Mobil tried to popularize synthetic oil for passenger vehicles back in the early 1970’s. At the time, Mobil was promoting 20K or 25K oil changes with synthetic, but they soon backed down from this. Synthetic oil is a good choice if you have a vehicle with a high performance engine (in fact synthetic is required for many of these engines).
