THE NEW STANDARD IN AFTERMARKET FILTERS
Doc's Diesel Filters are spec'd and designed to meet or exceed the quality/performance of the original filters (OEM's) that come in your vehicle. Doc's premium grade media filter paper used on all Doc's Filters is what sets Doc's above the rest.
Use it with every tank
Doc's Diesel THE DIESEL TREATMENT
Easy and simple to use.
Great stuff. Improved mileage while towing and commuting. Slight increase in performance as well.
SO far so good. I bought a Cummins filter pack with fuel, air and oil and all the filters included were spot on. Good job!
Improvement on fuel mileage for sure
With hi prices on fuel I’m looking for any edge I can get. Got about 2-3 mpg more. Worth it adds almost 100 extra miles to a fill up. Truck also seams to accelerate faster.
