schaeffer 15w-40 in kawasaki 29 dfi


LawnSite Member
I bought a turf tiger with the kaw 29 dfi engine last week and they told me to change the oil and the filter at the eight to ten hour mark to get rid of the breakin oil. my question is can i use schaeffer 15w-40 synthenic oil in this engine? i have schaeffer oil in all of my farm equiptment and vehicles and i have good luck with the oil. i just didn,t want to buy different kinds of oil. the manual said to use 30wt or 10w-30 or 10w-40. i don,t think the oil will be too heavy, but i would like some different views on this subject, but i don,t want to void the waranties on the engine. any information would be appreciated.

I have heard of some LCO's doing what you talk about, using 15-40. I just started doing it my self, I buy a 55 gal drum of it, was using different oil for the mowers, but figured it would be easier to have just one oil on hand.

Most OEM's recommend a 50 to 100 hr. break-in period on conventional oil before switching to synthetic. This gives the rings and other moving parts a chance to break-in.

It's all I use, in everything.

Kohlers, Kawasaki's, my new diesel Mercedes, Volvo roll-off truck, Duramax, Honda Accord, whatever.

It all get 5w-40, never had a problem.
