Proper oil for GY6
I just changed the oil in my scooter (Wolf RX 50) to get rid of the break in oil. I replaced it with 15W40 like the manual and sticker on engine said to. It seems like 15W40 oil is mostly used in diesel or heavy duty gas engines. Should i still be using this type of oil in my scooter? Also would it be bad if I went down to 10W40?
