monoped Posted March 25, 2009 Report Share Posted March 25, 2009 Hi - I run mine on 50:1 fully synthetic. Quote Link to comment Share on other sites More sharing options...
brian h Posted March 25, 2009 Report Share Posted March 25, 2009 Hi You can safely use 50 - 1 ratio on a MAR - works fine on Motul or Belray synthetic - no problems. Brian H Quote Link to comment Share on other sites More sharing options...
