Suzuki recommends the use of SUKUZI PERFORMANCE 4 MOTOR OIL, or an oil which is rated SF or SG under the API classification system. The viscosity should be SAE 10w-40 if a 10w-40 isn't avalible 10w-30, 10w-50, 15w40, 15w-50, 20w-50 can be used depending on the temprature. I would stick to 10/15w 40/50 to be safe.
10w 40 or 10w 50 this is for the southern part of the country
10w-30 in the winter and 10w-40 in the summer.
10w-50
Most people swear by rotella t brand. weight can be 10w-40, 10w-50, or most common is 15w-40
10w-30 advanced synthetic motorcycle oil
yamalube 10W-30
Any good name 10W/30 oil is good. Changing it at intervals of about 5,000 Km is more important than type of oil.
Yes but I would not mix these as the viscosity is not the same.
5W-30
Just a good grade of 10w/30.
10w-30 or 10w-40 oil
