Klots is the recommended filter oil for my Fleet Air Filters and the results show why. The filter oil traps dirt on the outside of the air filters and there is no evidence that any dirt is getting through. My oil sample reports show that no significant silicon(dirt,sand,etc) is getting into my Cat engine. I wouldn't substitute with any other brand.

Great oil !!
It’s the only oil I use on my Fleet oil filter
It great I used it all time can't complain
Can't really say, just bought filters and they were already prepared with oil.
Fleet air filter work good my truck thanks
I really like hearing the turbo, with the stock air filter the engine was mute.
I received a Fleet-air filter that I can't use yet. For some reason the cone has a hole at the tip. There's a plastic plug that is supposed to seal it. My plug has a hole in it! Fleet-air said they will send me a new plug. Pittsburgh Power needs to inspect their stock, and get Fleet-air to mail them the plugs needed.
Make a good job

I love the product and I change the wraps between 30 and 50k miles. And I change the Incan filters around the same time. It’s a very good product.
Love the product. I could feel more low rpm power right away. Hearing the turbo whistle is a plus too
