John Deere 7830 6.8L 150hrs/1 year - HPL 15w-40 CK-4 Cold Climate

[wwillson]

This is the first sample from this tractor of HPL 15w-40 CK-4 Cold Climate. The previous oil was Northland 15w-40. The HPL has been in the sump for 150 hours and 12 months. Our plan is to run this oil and only change when the UOA says it needs to be changed. With a sump capacity of 28 quarts, it's pretty expensive to change and there is no reason to dump good oil on a rote annual oil change. This oil will be sampled next spring and should have around 300 hours. Given the very dirty environment Ag machinery runs, the Si is quite low. The JD engine air filtering system is doing a great job.

[edit] I forgot to state that this is the 15w-40 Cold Climate formula.

TBN Wow!

 

[fantastic]

The Visc. & TBN are doing very well. You're right about the silicon being low for a real dirty environment. This is always a joy to see "Off road" equipment UOA. Thanks for posting this one. It'll be interesting to see how the HPL pans out with double the runtime.

Yes it will. My guess is we will get three years and about 500 hours, but we'll change the oil based on data not guesses

Looks good, overall. Very likely that extended OCIs are going to be successful here.

How are you going to track wear rates?
Per hour? .146 ppm of Fe
Per 100 hours? 14.6 ppm of Fe
Or convert it to an equivalent "per mile" basis? (assumed avg = 35mph) 4.2 ppm of Fe per 1k miles

Did a VOA get taken? Just curious if a base number for the Si is known? The rest of the contamination is very low, especially the soot for 150 hours of exposure.

What kind of service factors does this see? Heavy loading all the time? Light loading? How much idle time?

Probably per 100 hours. I don't think it makes sense to convert to MPH, because tractors might average 4.0 MPH, so the comparison may not be valid.

No VOA, but we can get one.

Medium loading most of the time and not much idle time. We don't like to work our engines to the limit, because they will not last as long. Overhauling these engines is a very expensive endeavor.

Interesting they call a 15w40 cold climate. I wonder what they consider as cold.

I'm sure this oil was formulated for a specific application. @High Performance Lubricants can tell us.

 

[PiperOne]

I find these newer 15W40's that have really excellent cold flow numbers very interesting. HPL cold climate lineup is crazy good but there are even some others that are making 15W40's that, on paper anyways, look more like 5W40's.

That TBN number is.....wow. Great results.

Shell’s take on a “cold climate” 15w40 diesel oil is basically that it’s a synthetic oil.

Synthetic or not, it is still limited to the SAE J300 ranges for a 15W.

I plan on using their 15w40 oil in my tractor next year. Using Amsoil right now.
