Re: Synthetic Motorcycle Oils



Hydrocrack I haven't heard of. The really good motorcycle oils 
Motorex, Motul, Silkolene, and I'm sure a couple I've missed offer 
full Ester based synthetics. Mobil 1 , Castrol, Quakerstate etc are 
PAO  based. PAO's are petroleum based. Ester based are truly 
synthetic, the base stocks having no petroleum. All of the better 
bike specific oils have additive packages designed for bikes. Higher 
amounts of zinc are only one of the additives that these motorcycles 
specfic oils have. Remember we also for the most part have wet clutch 
and gear boxes that share the same oil as the engine, unlike cages 
and BMW's so we need different additives than cars. As for what to 
use. Well Triumph branded Mobil 1 is very good. Motorex Power Synth 
4T is a full Ester based synthetic, it's what I use. Motul 300V is a 
full Ester based synthetic. Can't remember which Silkolene is full 
Ester synthetic.
