Yes, it is a CK-4 rated oil. It's an F-350, and yes, it does a considerable amount of towing. Their Lebanon facility is actually where I pick up my oil. I had never heard of it until I started working for an excavating company that used it.

I don't think I have seen a UOA on here of any D-A oil, so I thought I would post one I had done.

And thanks for taking the time to help, I appreciate it.

Geesh, just when I thought I knew for sure which one was the better filter, you go and say that. 😂

Okay, well if I am understanding this all correctly it looks like the Donaldson would be quite a bit better since it’s beta 1000 micron rating is almost as low as one of the other filter’s beta 200 micron rating and actually lower than the other one’s beta 200 micron rating. Seems like quite a...

So the way I understand it, it’s basically an average of several different tests. So I assume if doesn’t say TWA, that it is just the result of 1 test instead of an average of several tests, right?

Thanks! When it says "TWA micron", does that mean the same as when it says "particle size"?

I did find some info talking about it but still it doesn't totally make sense to me.

I'm trying to figure out the best filter to use out of 3 different ones as they all seem to fit my application. the problem I am having is understanding the beta ratios because they are not worded the same. The filters are Fleetguard HF35503, HF30730, and Donaldson P566400. On one of the...

I've decided I'm going to go with PU. Thanks again for all the help.
