quote:I found this FAQ on Mobil 1's website. Obviously RedLine and Mobil 1 have differing philosophies on overall synthetic basestock performance in gasoline engines. Anyone care to comment?
Q.Red Line Oil claims to have 100 percent polyolester base stocks. Are these different or better than the base stocks used in Mobil 1 with SuperSyn™? A.We are very familiar with polyolesters. In fact, we manufacture them and use them in our aviation jet engine oils such as Mobil Jet Oil II® and Mobil Jet Oil 254® and in our refrigeration compressor lubricants, where the polyolesters are utilized for their compatibility with new HFC refrigerants. Polyolesters are indeed excellent at high-temperature oxidation stability and low volatility. However, our work on automobile engines and jet engine designs has shown that polyalphaolefins (PAOs) offer the best all-around performance for gasoline engines due to their:
- Being completely compatible with conventional oils and gasoline engine seals.
- Providing both low- and high-temperature performance.
- Providing a stable oil in the presence of water and moisture.
- Having anti-rust capabilities.
