just wondering what oil would be better for best protection.I have the motomaster preamuim 2 stroke oil or would the amsoil hp lnjector oil be better protection.I have been runnin the motomaster would it hurt to go with the amsoil.I think the motomaster is a demestic and the amsoil is a synthetic oil info on this would be nice thanks.
to be honest, there are some nice exotic oils out there.. the best oil i think, is castrol R40. its expensive and hard to use, but in wear and friction tests has proven to be the best following some synthetics..
also, synthetics for injection tend to be thinner than synthetics for premix.. thick is good.. if your fouling plugs it may equally be rich mixture or too much oil.. consult the post on plug chop for pics of plugs.. I use Motul 800, its a dirty oil, you need to be running hard to burn it cleanly, but it gives a mean oil film..
Castor based oils are generally the best.. Castor based oils are still used to lubricate some jet engines..
