Engine oil For DK series Tractors.......Winter is just around the corner

[brain55]

Anyone have any thoughts good or bad about running the 15/40 Chevron Delo in their diesel tractors? I'm a complete noob when it comes to diesel engines and am approaching the 50 hour mark. Thanks.

I don't run anything but 15/40 Delo in all of the equipment I service. I have opened up engines with thousands of hours and would have sworn somebody took them apart before me and cleaned them up. No black film or anything.

if it meets the API specs.. go for it.

Delo is good oil. never hear anything bad about it.

My confusion started after reading through the Kioti owners manual, It states use a API class CC or CD, After consulting the API web site I learned this class has not been manufactured for some time and are not recommended for this era of diesel engines.

The info Kioti provides must be some what out of date I figure.

It's OK to use any later rating (e.g. it's OK to use CE where CC or CD is specified). Older documentation would specify the rating of oil available when written. That oil spec (in the manual) can be superseded with a newer spec after a few years, or even before the manual gets printed. Generally, the oil on store shelves is the latest spec or one version previous. The current ratings for Diesel oils are CH, CI, and CJ.

you will be hard pressed to find CC or CD on a shelf..

I have performed a lot of oil analysis tests on my Subaru Outback XT and one or two on my Jeep GC through Blackstone Labs. I tested many of the higher quality synthetics that are generally available, along with Wal-Mart's Tech brand. I did not test Royal Purple or other oils like this not generally available at the local Wal-Mart or general auto parts stores.

The least effective was the Wal-Mart Tech brand, but it was still usable after 3500 miles. The best tested was Mobile One and still had quite a bit of additives left. I tested all at ~ 3500 miles as the Subaru was/is still under warranty and required oil changes at 3,750 miles. I have standardized with Mobile 1, but all had good properties at only 3500 miles of usage.

Some years ago I also standardized on K&N oil filters due to others tests that placed it and Purolator PureOne tied for first place by a significant margin above the many others tested. PureOne is available at local auto parts stores usually for a few dollars less than K&N. And K&N needs to be ordered from Amazon or race parts shops like Jeg's Racing or Summit Racing. I prefer the large nut on the bottom of the K&N for removal of the oil filter with a socket.

Over the years I have also standardized on K&N air filters for all of my vehicles. The oil tests also show the K&N air filters are doing their jobs, even though I only clean them every couple of years. I will try and find one for my Kioti, but do not expect to be successful. Same way with the oil filters

Here is an article I gleaned from elsewhere, maybe a post on TBN. I will standardize on Mobile 1 for my tractor also, due to its tested rating from this article, availability and price vs. the #1 and #2 oils. But in the end, I think it is difficult to purchase a bad oil these day as long as one stays with the major brands.
