Hello board,

Just bought an 03 Champion with a 150 HPDI v-max. I am the 3rd owner and only have the information from the 2nd. He ran Citgo twc3 oil in it, but only put around 12 hours on it during his ownership (hence the selling). I was wondering what do I need to do to help this engine. It runs fine and has no issues, just trying to make sure she is treated well. I have read where Ring Free is a must as well as Yamalube, but some disagree on the oil type. Any help is appreciated.

Thanks!
