Just put it in at 10 hr. service. Seems OK. Haven't used any in 7hrs., anyway. Used 20W50. Yes, I checked the manual and with the dealer, this oil meets all KAW. specs.

 

Go to http://oilanalysis.com/

Then go to "car and truck lubrication" them page back to 4-11-01.
You may not like what you read about syntec.It is a "hydrocracked" petrolium oil according to the "pros". Check it out.

 

Ooops! you need to go to "message boards" to get to "car and truck lube"

 

I put Amsoil 20w50 synthetic V-Twin oil in mine. It seems to work pretty well, but how can a guy really tell if his oil is good or not? As long as it meets Kawies specs, use it.
