Hi Folks -
This is a JH Engine, 1.8L, 8 valve and it calls for an oil with an API SF. The only thing I can find i the US that is close is an AMSOIL Synthetic Motorcycle oil. This is the description:
"Synthetic High Performance 20W-50 Motorcycle Engine Oil
AMSOIL Synthetic High Performance 20W-50 Motorcycle Engine Oil is specially formulated to provide tough lubricating protection in the most demanding operations. It is recommended for use in all four-cycle motorcycle and ATV engines, including those with wet clutch systems requiring API CD, SG-CG or SH-CD oils.
AMSOIL Synthetic Motorcycle Oils are specially formulated with high levels of zinc and phosphorous for superior protection of cam lobes and other high pressure components. In fact, AMSOIL Synthetic Motorcycle Oils contain more zinc and phosphorous than other popular motorcycle oils (see graph). AMSOIL Synthetic Motorcycle Oils leave a wear scar up to 40 percent smaller than the scars left by other popular brands in the ATM D4172 Four-Ball Wear Test.
AMSOIL Synthetic Motorcycle Oil
SAE 20W-50 API Service SJ, SH, SG, SF, CH-4, CG-4, CF-2, CF, CD, JASO MA - Product Code: AMV"
Any ideas if this is OK, or for a replacement?
