Hook n ladder 1 Posted December 21, 2008 Share Posted December 21, 2008 I need some help. I had a reman motor put in my 98 CH613 and before I left the Mack dealer I asked about using bio. He printed out a bulletin saying Mack trucks only approves of B5 bio and not anything else in the E-techs, Ascert, MP7 and 8. SO the service manger says thats about '98 and up.I'm in the CHicago meto area (SOUTHSIDE/WHITE SOX) everyone has bio of b10 or greater..or "might contain bio". What the hell is that????? I can't find non-bio or B5 anywhere near me.My question is this.....is anyone running higher % bio and having any problems???????????? or having problems with any bio??? ( I'm familiar with the changing of the filters soon after a few rounds of bio).thanks Quote Link to comment Share on other sites More sharing options...
