Reply To: Engine Oil GV 125 (carb)
Agree with 10W-40(or 50), but just as important; change it at least once a year, remember also the filter.
BTW… does the GV250 have the larger oil-cooler (similar to the GT’s?)
Old and grumpy,(?), have fairly wide engine & tuning experience, "restoring/resto-mod" on cars & mc, worked as electronic tech. (retired).
