My Yamaha Scooter calls for 85W-GL-3 or 10W-30 SAE Motor Oil, I cannot find 85W GL-3 Oil Anywhere, can;
1. 85W-90 GL-4 be used in its place?
2. Why does the manual lists 10W-30 SAE as an alternative?
I live in the North East where temps can range between -10 and 100+ what range oil should I use 10W-30 or 10W-40?
My bike is fairly new and has low mileage (500) so is still in the breaking period, when I change the Oil should I stay with Mineral, Semi-Synthetic or FULL Synthetic?
Please advise,
