I use Lubrication Engineers, Inc (LE). Speciifcally, Monolec Tetra-Syn. Yes, I sell it but its the best engine oil on the market. It's the best because unlike the major manufacturer's, we want to sell the best, not the most. In fact, we print this right on the bottle, "No other brand of petroleum lubricating oil whatsoever, regardless of price, will be found superior in condition at the end of any given period of use."
LE's Monolec Tetra-Syn Engine Oil exceeds the minimum standards set by American Petroleum Institute (API), providing the ultimate combination of performance, protection, endurance and efficiency. It is a best in class 100 percent synthetic gasoline engine oil, and the secret to its superiority is the proprietary additive package designed to deliver resource-conserving fuel economy, protect emissions systems, keep engines clean, keep deposits to a minimum, and mitigates wear in Low-Speed Pre-Ignition (LSPI) conditions.
Monolec Tetra-Syn when used with oil analysis, safely allows extended drains to 12k-15k miles reducing oil consumption and cost of use. Monolec Tetra-Syn also extends engine life, reduces engine temperature, and increases MPG. Your engine will purr like a kitten with LE's Monolec Tetra-Syn in it.
