I just repowered a couple months ago to an E-Tec 150 and my cousin got a new Stratos with a E-Tec 200 H.O. on it. We both have been discussing getting our engine switched over to run the XD100 with the dealer, but the dealer told us that he just talked with a Rep and they are now recommending the XD50 oil. The rep said something to the effect that they were not getting the perfomance that they thought they would get. Anyone else hear this?
