I used amsoil with oem filter, but after reading up on it plan on using purolator pure one filter next time.

 

Oil is oil. Personal preference. All the stuff out there about better performance and stuff is jibberish.

 

amsoil all the way, firm believer, bought a cr250 and the guy told me how bad it was at fouling plugs, so i jewed him down 500$ brought it home, cleaned the tank, washed it good, 93 ocaine and 32:1 amsoil, never fouled another plug truth!
