Nope, no confusion here.

Your owners manual is obviously not the same as mine for the 2020 model Kawasaki FR651V/FR691V/FR730V engines!
My owners manual is Kawasaki part # 99920-2289-01 (Sept 2016)

It's for a FR651v but no, not a 2020, guessing they changed it at some point, that's why I was curious to see what updates they did to the chart.

The only issue I could see is if the engine has a catalytic converter, the aviation oil might contain some higher zinc levels etc. that could cause premature failure of the catalyst. If not I say go for it.

I posted an explanation why the aviation oil is not better than the automotive oil. A link provided by another poster explained the same thing in different words. Apparently what I posted was ignored, so I removed it as I will this posting in a few hours. Because your Piper and the Kawasaki are both air cooled, doesn't make them equal in any way. Your aviation oil doesn't carry an API rating because it can't meet an API rating other than SA or some other low rating. Yes, it's good oil, but it's not automotive oil. But like others have said, "You money, your machine and your oil."

From: "West Uncton"?
"Yes it's good oil, but it's not automotive oil"

Air cooled Kawasaki engines are automotive engines, so they must use only "automotive" oil?
I didn't know!

I think I am done with the varied opinions and theories.
I will sit tight now, and wait for some factual information from the chemists and engineers at Phillips Petroleum.

Wait, wait, just one more input...

Here are the specs for the Phillips oil.
The kinematic viscosity allowed by API for 20w-50 at 100’C is minimum 5.6 cST and maximum 21.8 cST. Also given that the viscosity index is 144 this is indeed a very stable oil.
From this information I conclude that your oil will suffice for its intended purpose and your lawn mower will not fall out of the sky. (I couldn’t resist the attempt at humor).

Now THAT......IS some INFORMATION I TRULY do APPRECIATE !

P.S. I bought the used twin Comanche for my son to build up his multi engine time,..... I only flew it twice, but I paid all the bills.
I was then flying the DC-10...and getting paid for it!
It worked out well for him though. He is now an ATL chief pilot for Delta,..... and I have been retired for 20 years..


Fried1765....OUT!

30w cheap **** in engine. Mobil 1 15w50 in hydrostatic. Being using mobil1 in hydrostatic for 20yrs. Have a lesco hydro walk behind. With mobile 1 15w50 in hydrostatic. Zero issues. Much better cold weather performance

I live in Florida for 6 months each year.
While there, my mower will sleep in my storage building, with a trickle charger attached
Thus, I am not even remotely concerned about "cold weather performance"

You basically posted this wanting people to say it is ok to use 30 year old aviation oil in your lawn mower. You got some opinions that said no and then try and defend why it is ok. You have made up your mind so go ahead and use it. I stand by my earlier post and say it is probably ok but why chance it. The age of it would be my concern, not the quality. If it does fail it is not like an airplane where you might crash and burn. Would you use it in an airplane tomorrow?

I would like to read some FACTS about the SHELF LIFE of motor oil?
Perhaps my mistake in this thread was not highlighting the word FACTUAL in my initial post.
