hi Everyone,
i am a gal from Singapore who just bought a year '91 XR250RN. will be needing an engine oil change in 2 weeks' time..
the previous owner used fully synthetic oil.. i am just wondering which is better, semi or fully syn oil for my 14 year-old hubby? what difference does it make?
Also, good if anyone can tell me exactly how many litres is needed? all i know is 1 litre++
did a search on this forum but did not find similar posts, please help! thanks in advance!! :nod:
