Klotz Filter Oil – Case Quantity – High-Tack Air Filter Oil for Washable Diesel Air Filters
Case 10 x 15.25oz Aerosol
After 40 years working on diesel engines, I’ll tell you this plainly — most “filter problems” are actually oil problems. A washable air filter that’s under-oiled lets fine dust through. One that’s over-oiled kills airflow and coats the intake.
That’s why I use Klotz filter oil.
This oil is engineered specifically for washable air filter media. It has the right tack level to grab fine dirt and hold it without migrating, dripping, or choking airflow. When applied correctly, it lets the filter do its job — stop dirt, maintain airflow, and protect the turbo.
This listing is for a case quantity, intended for fleets, shops, and high-mileage operators who service filters regularly. It keeps your maintenance consistent and eliminates guesswork when filters come off trucks.
Bottom line: a washable filter is only as good as the oil on it. This is the oil I trust to keep engines clean without creating restriction.

6. Competitor Differentiation (Mechanic Truth)
A lot of oils are either too thin or too sticky. Thin oils let dust through. Overly sticky oils choke airflow and create messes inside the intake.
Klotz hits the balance. It grabs dirt without suffocating the engine, and it stays where you put it. That matters when you’re dealing with turbocharged diesel airflow and long service intervals.
You can’t cheap out on filter oil and expect a washable filter to protect a six-figure engine.
