Low Engine oil FR730V

[StarTech]

Kawasaki updated their oil recommendations a couple of years back. 10W40 is the minimum requirement. 20W50 is the maximum requirement. Anything in between will work too.
Motorcraft Super Duty 15W40 or Shell Rotella T5 15W40 would be a good place to start.
If it continues to burn oil, move up to a 20W50.
Burning oil on 20W50, I think you know what comes next.

That is why I prefer to just use a 15w50 synthetic as it more of a middle of the road blend plus around here Summer heat is now around 98+F but MParr said above those are good blends to start with.

And said once start burning oil at the 20w50 level it time for a rebuild or replacement.
