Caterpillar Engine Oil

Theres many suggestions used out there but i am using Kendall 15-40 for older engines and Pennzoil 30W for gas engines [starting engines]. A straight 30W diesel engine oil is preferred also for the old engines.

I always enjoy these oil discussions.
The Cat mechanic who delivered my 17A checked the pony level before starting it and discovered that the "oil" was some kind of milky whitish gunk. don't know if the previous owner had used the kill switch rather than turning off the gas or what it was all about, but it was satisfying to drain it out yesterday, run a little diesel through, and fill with fresh oil.

You will then have about 4 days of material to read. It IS interesting. :amen:

Rotella heavy duty 30w. In both diesel and pony.

Golly, I'm gettin all confuzzed now.

Rome--I like your captions!!! I use Kendal series 3 30 wt in diesel and 30 or 40wt non detergent in pony of any brand

Delo400 15W40 ....NOT the LE formulation that is for the engines with diesel particulate filters. I need to see some data that shows how the new oils perform in old engines with flat tappet lifters before I will use them.
