What type of oil should you use in Kawasaki FR691 V engine?
Use Kawasaki 10W30 motor oil or some good dino oil in it until
you get at least 110 hours on it then you can change to synthetic.
We prefer the use of 10W30 Mobil 1 synthetic or Royal Purple but
ONLY after 110 hours otherwise the engine will nevr break in and
the engine will burn oil.
