You are entering the dark side.... Oils cause some HUGE debates on this forum....
Are you happy with the Merc oil you're using? If so, why change? If it's for price, just remember "You get what you pay for". Is saving a couple of dollars worth the risk of destroying $15,000+ worth of engine?
I have been running it for about a year. It is a little more expensive but no additives are needed to the fuel to help eliminate the carbon. I was just wondering if anyone else out there was using it?
