I don't want any lab quotes, just plan and simple real world experience!
I tried the Mobil One 15w 50 car oil in the RC, question for you people that use car oil in a bike, do you find that the oil burns quicker in the motor (high temps) and that you must top up the oil level more frequently, than if you had motorcycle oil.
Observation: 1st time using the car oil in a bike, but I had to add about a litre of oil to the bike. Quick fix until I could change the oil today. This was the 1st time I had topped up the oil level in the RC, before I used Castrol R4 super bike oil, and never did I top up the level with that stuff.
Anyway, I have switched to the 5W 50 Castrol car oil, seems this stuff is very similar to the R4 bike oil from the analysis in the last sport rider mag.
So what's the story people, does this car oil foam up and burn off or what?
