Royal Purple Motor Oil

[Chappy]

Anyone out there using Royal Purple Motor Oil in their Gen111?

I am curious what this oil is like they make some pretty promises on how good it is.

Cheers

Hi mate. Do a search. There's heaps to read.

im using their 10W-40 in my VT, cant say i noticed a difference in power but it definitely seems smoother, piston slap sounds quieter and doesnt last anywhere near as long, valvetrain seems quieter too. well worth the $ in my book. my only gripe is that to get more than 5L, you have to buy 2*5L packs (no top-up sizes)
