I have 96 150 fast strike on a 97 basscat pantera II it has 400 hrs on the motor do not know if that is alot of hours or not but I wanted to make sure I was using the best oil in it.The guy I bought it from was using johnson brand .Also is there a fuel additive that I can use that will help keep motor clean.Any help would be greatly appreciated.

Thanks Brian

Welcometo the boards Brian,
XD-50 from BRP will work wonders in your motor bring a clean, empty gallon jug to your local dealer and save about $4.00 off per gallon. Add carbon guard for a few tanks and then use BRP engine tuner to blow out all the junk. The XD-50 will keep you clean and a decarb after 100 hrs will verify.
