Hi Michael The oil I use is a multigrade 15w/30. It can be used for diesel engines (turbo or non-turbo) and for petrol engines. It goes in my M20, A10 and Triumph T110 (it also goes in my tractors, telehandler, bachoe loader etc..). The M20 does the most mileage and seems OK with it. My M20 dribbles a bit (don't we all when we are getting on a bit!) so the oil is always fresh! Regards Pat

Don't the HK Harley dealers sell their HD360 20w/50 ? That is still a mineral oil I believe.
