Does T6 come in 15W40? I thought all synthetic Diesel oil comes in 5W40. Personally I would not switch with 150 on the clock, stick with the 15W40. There are thousands of old farm trackers that only see a oil change every year or two or three and they seam to keep on running. Twice a year oil change should be just fine, just let it stretch it's legs once in a while.
