who makes rural king's 15w40 oil? it's way cheaper than even walmart...

If you really think because a brand name supplier makes the oil for someone it has to be good I have a swamp I will sell you for a good price. That's not to say your cheap oil won't do the job - depends on how hard you operate, how all the parts on your machine fit, and a whole bunch of other items. If all oils that met a spec were the same you would not find a major like Exxon-Mobil making 10 differing oils all that met the same spec but have varying costs. I've stated on here before that there have been some items on machines where we debated whether or not to ship sealed for life vs letting the customer change because the "meets spec as shown on the label" oil some use in a change is do bad, and then the customer wants warranty because his neighboring contractor who services with the best has much better "luck", only it isn't luck. Cheap oil - yes I've used it in my older equipment that leaks bad, but once the leaks are fixed it gets quality fluids. All of our newer equipment gets top grade and we don't have failures. My nephew who is caught in a bind where he farms with junk uses the cheap stuff and is lucky to have half of his tractor fleet operational at any time. He needs a large fleet of old tractors because some are always down. Is it fluids or just everything worn out? No way to tell. Do tractor brands like JD, NH, and Kubota jack up their prices? Of course, because they do not produce their own product - there is a middle man. Does a brand like Rural King have the same middle man markup? No, because they are buying the cheapest oil that meets the specs and do nothing with the oil supplier to develop specialties. And yes, in my years, I have worked with our lube group with suppliers selecting specific oils that will do the job even yo the point of having developed special place offerings. The Fisk us in the owner.

Its the same business model in all operations. I have loggers that run older stuff. they have a spare of almost anything. Its age and wear on parts that breaks. These tractors are not having bearing failure due to cheap lubes when they break (loggers in my case) its a turbo going out cause that piece of equipment has 10,000 hours on it. A hose blowing out cause its chaffed from 8 years of hard use and chaffing, or an oring blowing out, those failures do not have to do with the Warren oil there using in the hydro system or Mystic brand oil there using in the engine?

And I have loggers that run all newer stuff and they all have spares as well too cause the new stuff breaks down as well weather they run dello or rotella in it or mystic. I have loggers that run all name brand oil and they break and I have loggers that run whatever is on sale at the parts place and they have no more engine failures or anything than the others, that I notice.

agreed.

much of our road construction stuff breaks from operator error/use/abuse.

I have seen enough two stroke detroits ruined by cheapskates using the lowest cost four stroke oil instead of SF-2 oil.

I dunno.. This list looks pretty full

( warren and WalMart are listed. )

Sounds like fuel dilution to me, not the oil.

Fuel dilution was right at 1%.

It's a lube oil thread. One of the top three biggest wastes of bandwidth on the internet. Nobody convinces anyone of anything. And I don't know why I am involved. I really don't care what anyone else uses, and don't plan on changing my mind about what I use.

1% dilution can have quite a bit of an effect on kinematic viscosity. What are the condemnation limits for fuel dilution for that motor? Condemnation limits are 2% for my Detroit Diesel. I have never had a trace. Diesels inherently encounter some form of fuel dilution, but gassers, not so much unless there is a problem. Oil samples I have seen from others that were encountering fuel dilution, the viscosity is considerably off compared to the base number. I have seen XXw40 oils disintegrate pretty quickly into 30w oils due to small amounts of fuel dilution. No one says you should change what you are using, but with 1% dilution, depending on motor, you better look into it. It tends to only get worse with time. And even the best oil on the planet can only protect so much when contaminated with fuel.

Sounds like an issue "other" than oil...

I plan on a retest at a shorter interval. And I did use a different oil.

More proof that diesels were built to operate at extended periods at full rated rpms and at full power.
Stop/start, putting around, light load and idling ruins a diesel. Fuel is not fully burned, cylinder walls wash down oil gets contaminated and the oil is not hot enough to evaporate the light ends and moisture from the sump.

Can't tell you how many slobbering diesels I've seen that were cured by actually working them vs putting around on them

Could be, but the diesel in my 2006 Jeep Liberty, operated as any other basic transportation vehicle, never had any fuel dilution issues. And it got 10,000 mile oil changes. I took it to around 110,000 miles and then my son bought it off of me. I didn't sample every time, but enough to track trends in oil samples.
