Ok guy's, here is my 2nd test.

[Edit data]

Now how about some peer review research, see if anyone else can show same result with regular oil and synthetic.

Mike Gaines

Excellent work there Mike.
I am up for it, I have some thermistor driven test gear archived....digital outputs.
Two immediate problems I forsee is "dino oil" is very difficult to get, locally.
And it is our winter here, for what that is, and so mows are pretty ordinary, time wise.
Up to an hour is possible, at load.

Stay tuned :)

Thanks kk, I wouldn't think the outside temp would matter much as long as you check each time you start at the same temp.
I was using HD 15w40 the 1st time, guess I should check 10w30 Dino next, I also got a good price on Rotella t6 5w40 synthetic that I will be running full time after next test on 10w30 Dino.
This is costing a bit of money but I have my interest peeked and really want to check this out.

Mike..

Thanks, If we could get more to contribute we might even find some manufacturers are (apparently) better at fan / shroud, fin cooling , than others. Kaw vs Briggs vs Honda vs Kohler.
Problem is uniformity of procedures and measuring devices.

Ok just went to dollar general and got 2 quarts of Castrol GTX.
I changed oil on Kohler Courage 23hp on my Husqvarna Z Turn I've Been testing all along, it now has Dino 10w30.
I did take new filter off and drained it for several minutes.

For anyone courious I'm recycling all oil I'm using, I take it to Autozone.

Next run will be on 7/16 or 7/17 that will be one week, I'll watch temp close and start at 80* to 82*

Stay tuned :thumbsup:

Mike..

After I changed oil to Dino 10w30 I went and mowed over my septic tank and lateral lines took about 8 min. Air temp. Was around 90* so that's 5* warmer that have been running and checking.
When I finished I shot infra red at filter it was 175.8* and block was 125.8, that's as hot on oil as I got after 90 min.
last time.

Full run and temps this Thursday

Mike, Good work, the temps are really low compared with my (liquid) oil in the Briggs Intek. Interesting ... What gun brand are you using in case any of us try what you did? It is always possible that electric driven sensors (like my Beedee) can vary with (tractor) input voltages, heat and even calibration. I did find that a DVM probe of sump oil was 10 degrees cooler than the Beedee gauge once. This is also analog dial (Beedee) vs digital DVM readouts. Will we find that the Kohler runs cooler??? Even ? assembled in China?? They do make motorcycles and lots of cars.


Edit. Just refreshed that you run a zero turn and I run a big box special. Cynical thought, are riders simply designed to burn up and rebuy...naaw, they wouldn't do that , would they?

The guns name of manufacture is (General) it is a small hand held model # 20140402278
I bought it at Lowes about a year ago.
I've checked it to several known temps and it's right on the money.

As far as what I get take that with a grain of salt as to the accurate temperature just what I'm getting on this unit.
I'm always trying to point gun at same spot to a good average.
Some day I might get a sending unit and try that going straight to the oil.

As far as my mower it is the one of the cheapest zero turn you can get its a RZ4623 made in 2013
I hope we can get some interest and a few others will do what I'm doing.
That way we might see a real difference in oils.

Trying a link.
If it works this is what I'm using.
It worked for me, took me to eBay showing the little infra red gun I have.

Precisely why we (?) should be posting methods, despite the extra work.
I am going to use both gun and transducer type sensing. When I get me gun, I
am well away (remote) from markets. I will use what I have for now.

Over the India experience the Chinese at least follow some industry standard, albeit
they are known to steal the info at the design phase :}
Edit. Just refreshed that you run a zero turn and I run a big box special. Cynical thought, are riders simply designed to burn up and rebuy...naaw, they wouldn't do that , would they?

Heh.... I feel a solid class action coming on. Cashed up residents are getting into
tractor and ZTR rides in droves. The units are not priced at gumball (limited chew)
levels, they are a significant investment and sold (promoted) as such. To have a
dealer tell you your machine is "worn out" at four years old and less than 300 hours
of real work - in offering a trade up - is *fskn* insulting.... to your intelligence and the
manufacturing industry per se.
Then again, when I look at just how Kawa put together their rocker cradle I am pushed
to consider your cynicism very seriously as being the actual fact of the matter.

I digress.....

You guys motivated me so I broke out my KE thermometer , mowed, and took some readings. Remember I have a full sized oil cooler on the Intek with electric fan. I usually turn it on at 280F on the Beedee oil temp gauge. Today 82F mowing without bags out the shute on tender green grass. Trying to stay somewhat in the order of Mike's figures...

Engine oil was cooled with fan from indicated 300F liquid oil to 220F

Values : Oil filter (big fram) 110F
Sump case (block) 162F
Sump Plug (sensor 169F
Oil temp gauge 220F (liquid oil)
Oil cooler fitting 118F
Dipstick tube oil 180F *
Rocker cover 140F

*Dipstick tube oil=fished wire probe down into sump, which is a couple inches back of the sump plug.

The oil gauge sensor is like a small pencil and soaks in the oil pool, the KE thermometer pickup is a small 1/2-sized BB on a wire.

Edit. One wonders about the 40F delta between the gauge and the dipstick oil reading...Actually, the KE works like a wall thermostat sender and only the tip should be heated. I heated the length of the wire that was in the dipstick tube. I'll go with the Beedee gauge of 220F
