Oil Choice

[Bee-Positive]

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.

Absolutely correct sir.

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...

OK so what diesel eral should we use ?

I’ve heard good things about VP C-16.

 

[mikado463]

Hmmm…..never heard of this…..

well since you asked........Zinc or ZDP as it's often known has been reduced in oil over the years as more and more ICE's have utilized roller cams. Whereas flat tappet cams have used the additive in oil for lubricity for years. i am lead to believe the Kawasaki engine in my zero turn utilizes a flat tappet valve train, thus the question

Sorry for the confusion, it's model Z412KW. Engine FS651V

You read too much internet propoganda.

First of all zinc has not been reduced or limited. Phosphorous is what has been limited to 800 PPM but only for specific viscosities. Other (more expensive) addiditives have taken the place of the reduced phosphorous.

Your 10W40 is not subject to the 800 PPM limit and is capped at the same 1200 PPM as heavy duty diesel engine oils. That is very much in line with older formulatiins. and way more than needed for that little lawn mower engine.

ALL of these formulations are run tested for flat tappet wear protection using flat tappet engines and meet very demanding requirements.

Unless you are building NASCAR engines these limits are absolutely meaningless.

Hokie, thks for your reply and yes I fully understand the reduction in phosphorus (catalytic converter issues). it was when i stoped into the Kubota dealer and picked a new filter for the upcoming change the parts guy was trying to tell me I need to use kawasaki oil' cause of increased Zinc content. I knew he as trying to blow smoke up my skirt when he stated it was for better engine cooling !

Anyways I've just returned from Wally World with a 5 qt jug of Super Tech 10w40, all is good......

Super Tech is good stuff. Not sure about for small engines but it still should be decent stuff. Is that Kaw water or air cooled?

 

[mikado463]

Air cooled

 

[lmichael]

Air cooled

You should be fine. Just don't push your intervals if you stick with it. The Super Tech is actually very good stuff.

Taken from a John Deere manual for Z950R with Kawasaki air cooled engine. Same page is in the X739
manual which is liquid cooled. Just use a quality oil and change at proper intervals.


Gasoline Engine Oil
TS1744
TS1744-UN: Oil Viscosities for Air Temperature Ranges
Use oil viscosity based on the expected air temperature range during the period between oil changes.

Using single viscosity grade oils such as SAE 30 or SAE 40 can reduce oil consumption in air cooled engines.

The following oils are approved:

John Deere Plus-50™ II
John Deere Turf-Gard™
Other oils may be used if they meet one or more of the following:

ILSAC GF-6A
API Service Category SP
API Service Category SN
API Service Category SM
API Service Category SL
API Service Category SJ
ACEA Oil Sequence A3/B3
ACEA Oil Sequence A3/B4

My father has the same engine in a zero turn SCAG he got a few years ago. I change the oil for him when I head downstate and have him pick up the standard oil and filter that is recommended from the engine manual. I think with small engines it’s a lot more important to change it yearly at least or more if used a lot within the hour interval set by the manufacturer compared to the brand of oil you use. As long as it meets the specs that’s all that matters. Now I’m getting my popcorn ready. Once he gets a few hundred hours I may switch over to synethic but I’m not sure yet, d
