Anyone know what kind of oil is put into a 2014 Coachmen Mirada. I do not know if it is regular oil or synthetic. Does it matter if I switch it to regular oil. Is there a place in the coach that say...
Not sure I understand? How can 5wt be heavier than 30 on start up or cold? Wt is wt? from lighter to heavier? Would you mind explaining? I was lead to believe 10wt was transmission fluid. 90wt was differential fluid? Is synthetic oil wt different?
