Hey all, Just bought the 2012 assault. After all the engine problems with my 09 I want to make sure I am doing everything possible to make this one last! The owners manual says to run the first tank of gas pre mixed with Semi synthetic oil for faster break in, how about the oil resivoir? would you put semi syn in there too or the regular VES gold. The dealer told me not to even put semi syn in it because it was gumming up the valves. What have you done to break er in?
