Anyone tried the DFI Oil from West Maine in Direction Fuel Injection two strokes. They put their oils on sale at half price some times and the DFI oil from Merc. is extremely expensive. Is it the same quality /meet the same specs. etc? Don’t want to be replacing a $20,000 outboard early by going cheep on oil and I have heard that the big Opti is very sensitive on the gas mix oil and that the Merc DFI oil has a lot of additives and special cleaners etc.
