Absolutely correct sir.Unless that Kawasaki is a diesel, two people on here have given you wrong advice.
Sx for spark-ignition engines, gas
Cx for compression-ignition engines, diesel
The rest is your choice.
Since mikado463 does not state what model he owns I did the ready-shoot-aim method of answering as if it were a diesel. My apologies to all.
I believe the Z models are gas and the ZD models are diesel. Choose diesel or non-diesel engine oil accordingly.
Pass the pop corn please...
