i've used this lubro-moly lubricant before. i wish my engine could speak out, but have not noticed any real difference in performance or in gas consumption.
so my short answer is NO. YES to frequent oil change.
i've read it somewhere that gas and oil companies have invested tons of dollars in research and development to arrive at their respective products, and to better served the ever demanding needs of consumers and their technologically-advanced machines.
to add any foreign substance to their mix will dilute both formulas, hence, the predicted benefits, if any, will fall short of anticipated outcome.
just my opinion. joel
