How do you put oil in Kawasaki 250 four wheeler
can i put my vin number of my four wheeler on my four wheeler key
The oil you use in a four-wheeler is exactly the same as you use in a vehicle. If your four-wheeler is air cooled I highly recommend you use a 100% Synthetic oil in SAE 10w30 weight. If it is water cooled use either Synthetic or Conventional oil.
NO
drain you oil and flush it out
Car oil is not meant for the clutches in an ATV engine. You should get oil that is designed for motorcycle or ATV wet-clutch engines. It will say it right on the front of the bottle.
Dont crank it... Drain it out and put gas in it.
20W-50
you shift down from the park position.
10w-40 ATV or motorcycle oil should be fine.
A 10w40 oil with an American Petroleum Institute or API rating of SF or SG.
Detergent! Do not use non-detergent oil.
