Hello all, new to this site, got a 2003 baja outlaw 20 and just had a few questions. First is if you would recommend switching from regular oil to synthetic. Motor has 190 hrs on it and uses regular 25w 40. just wondering if synthetic would benefit me in any way. next question is anybody has a part # for a good oil filter to use. I go to the mercruiser website and it has multiple listings for V8's. Just trying to find the best one. Thanks a lot
