Well motorcycles have a sight glass in the crankcase used to measure the oil level. I noticed that the mobile 1 would form MANY bubbles, then return to normal. After a few days of riding the bubbles would get so bad that it would look like foam. Mind you I couldnt see it under the oil cap, but it was very aparent in the crankcase. I figured since in my mind this was the best oil it must be normal. Well a few years later I studied oils more and realized mobile 1 is not even true synthetic. I was PISSED! I did more research and talked to some motorcycle racers and settled on MOTUL double ester. As soon as I rode the bike down the street it was amazing to say the least!! the shifts were smoother, the engine seemed completely different. It truely felt like a whole different....well.....everything. Crisp shifts, more power (butt dyno) And I never got any bubbles/foam!!!

I WILL NEVER USE ANYTHING OTHER THAN MOTUL!!!!
