When this thread was started there were probably only two types of oil....engine and crude.

• The Japanese recommend an oil type that is JASO approved for wet clutch engines that share an oil with the transmission.
• That oil classification is either JASO MA1 or MA2 or generically MA
• AMSOIL explains
• There are other informative texts on this site that I recommend for anyone questioning oil types to use.
