from my experiences and motors Ive rebuilt that have used synthetic like mobil1, amsoil, royal purple. the wear in the motor isn't caused by bad oil. I believe the oil runs too thin when hot and can find its way to cavitation, or find it's way past the oil bearing on the left of the crankshaft.
I had a guy JUST LAST WEEK!! member from on here. he came up to buy ANOTHER crankshaft. his machine was NOT abused, its stock and in amazing shape. he didn't head the warning about using royal purple and it cost him another crankshaft.
on the other hand.
a 730cc motor I built back in 2005 (yes 7 years old) raced me with my can am 1000 and BEAT ME. this motor is running rotella 15-40 and was a race bike for GNCC and AGP NEVER FAILED YET!! and still runs strong or stronger than the day I dynotuned it.
ask yourself. spend $$$$$$ on the expensive snake oils. or buy a cheap [censored] gallon of rotella 15-40 and prevent this.
you can think, do and believe what you want.
It’s on the internet it has to be true omg I’d stay as far as I can away from that guy.
Makes no sense, does it? My uoas have shown most of the conventionals I've tried have sheared down quicker than the syns. (Though nearly all of them went 30 weight from 40 regardless). In other words, if syns are snake oils, then so are conventionals.
