The recommended oil is SAE 10w 40. If the bike is use in under-10 degrees go to 5w 30 oil.
The 10W stands for 10 winter. The oil is a 10 weight oil at cold temperatures and becomes a 30 weight oil when it is at full operating temperatures. This way it is a mult-vicrosity oil and can be used in the winter and in the summer.
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.
SAE 30 motor oil if the temperature is between 30 & 75°F.Colder use SAE 10 oil.Warmer use SAE 40 oil.
it depends. non-turbo = SAE 5W-30 for ambient temp ranges minus 20 to 100 F. turbo = SAE 5W-30 for ambient temp ranges minus 20 to 60 F SAE 10W-30 for ambient temp ranges minus 10 to 120 F SAE 20W-40 for ambient temp ranges minus 32 to 120 F

The difference is 10
Nothing at all except the name on the bottle and the high price you pay for the so-called motorcycle oil. I do recommend you use synthetic in any air cooled engine.
The W stands for Winter. The 5w30 flows easier at lower temperatures. It is a 5 weight oil at low temperatures where the 10w40 is a 10 weight at low temperatures.
SAE 30 as standard. SAE 10 for cold weather.
the difference is also doubled
