Amsoil is a true POA (polyalphoalefins, also called synthesized hydrocarbons) group IV synthetic oil. I use it and highly recommend it. I switched to Amsoil at 400 miles and could've done it sooner. Engine is well broken in and burns no Amsoil now at 10000 miles. I use a reusable Scott's Micronic stainless steel mesh in billet aluminum oil filter, and change oil every 620 miles. (1000 Kms)

Go here and select the G2156 - Motorcycle Oils White Paper
