Buddy filled diesel skid steer with automotive gas engine oil. Used this to help.
We all know that guy who will buy a $65,000 machine and then only service it once a year with the cheapest oil on the shelf from Rural King or some other place with ultra cheap, home branded, questionably quality oil. Yep. That is my good buddy.
So I go to the shop a couple weeks back and he is re-filling the skid steer engine with some ultra cheap, totally not to spec, gas engine oil. I question him and he states that it is perfect oil for the machine being 5W-30. I ask him if it meets the SAE ratings for the diesel, he repeats back that yep... it is 5W-30. So I go grab his New Holland book (C232 track skid steer) and look up the oil requirements, then I look at this junk oil, and I try to explain to him the SAE designations on the back of the bottle and the SAE requirements in the book. He looks at me like I have 3 heads and repeats that it is 5W-30, it is totally good. Someone.... kill me please! He has no clue what I am trying to explain.
So I couldn't sleep knowing what he is doing, and I ran to Amazon to see if I can at least get zinc to add to the wrong oil and try to help the cam followers and rockers survive this next year. I found this. I ordered a few bottles and had them shipped to his shop, and I explained to him that these need to be dumped in to at least make an attempt in not prematurely wear the engine that likely is worth $20,000 or more!
So the real question is, will he actually dump these into the machine, or will he toss them on a shelf never to be seen again? We may never know. But I bet next winter he will once again shop for the cheapest oil on earth to put in a machine that costs as much as some peoples home. He is who he is, you can never change that.

High quality replacement clips. Highly recommend.
I used these when replacing the headlight assemblies on my 2011 Honda CR-V. A few clips were already missing before I even started taking the bumper off, and of course a couple more didn’t survive the job.
These fit perfectly and snapped right in with no issues. If you’re missing clips or break some while doing a repair, these are a simple fix that gets everything secured again. Very good deal.
