Let's do this again.... :blah:
I am still puzzled why MV specs such a heavy oil for these engines.
10W-60/20W-50 seems very thick for a water cooled inline 4 cylinder.
Most if not all Japanese engines spec out 10W-40 and they put out bigger horsepower numbers.
My racing buddy tells me to use a 10w-40 (full synthetic) in the colder temps and maybe a 20W-50 (again full synthetic) if I feel the need.
The current trend in engine lubrication is to use lighter viscosities so that the oil can flow faster, reduce pumping loss, increase power and actually lower operating temps.
Yes, I know all about the shearing that our shared tranny/clutches put on an oil, but modern synthetics can handle this easily.
The current Mobil 1 motorcycle oils are very good, and yes, they are different than the car oils.
Do you know what your dealer actually put in your bike last service?????
Anyone out there actually know why we should use such a thick oil??? Just marketing for AGIP??
