I added a bypass oil filter after 3k on my truck. The mechanics at the dealer who do my warranty work have also added this product to their vehicles. It is the best addition to the engine since Mr. Otto invented the auto-motor.
Bottom Line
Yes, I would recommend this to a friend.

Great filters

I purchased this bypass system so I can have the ease of going to my local store to buy the filters. Everything seems great so far I would recommend to anyone. I will be purchasing another one for my fleet trucks
This is a excellent product. Very high quality. Works as designed. Also since there is nowhere to mount this filter system on my truck, I ordered a bracket system for my truck that I found on U Tube . I think this should have been mentioned.
It’s the best decision ever made, my duramax engine runs great
Bottom Line
Yes, I would recommend this to a friend.

Help keep my oil clean. Especially with a diesel it can get very dirty but this really helps keep the oil clean.
Bottom Line
Yes, I would recommend this to a friend.

No Oil Filter is better—none!

No Oil Filter is better—none! I have used this product since May 2020. My diesel engine purrs like a content kitten, and I have gone 15K miles between oil changes.
I installed a bypass filter on my 150 HP generator that I use for running a pivot sprinkler and water pump, historically I would have to change the oil (AMSOIL 15W-40) every 250 hours I had run on it; per the oil analysis (Blackstone). for the second year in a row where I exceeded 600 hours on the oil and the analysis has recommended I go another 70-100 hours before checking it again or changing the oil because it looked so good. This filter does only have a 1 year warranty, so I will be changing it at least once a year but it has paid for itself in the first two years and then some.
