BypassBy TOM, a Verified Buyer from Florida on January 22, 2025This 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.Bottom LineYes, I would recommend this to a friend.Was this review helpful?

Worth Every PennyBy BEAU, a Verified Buyer from Colorado on November 11, 2024I 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.Bottom LineYes, I would recommend this to a friend.Was this review helpful?

Seems to be doing a good job at keeping the oil clean. 1500 miles into the oil change and the oil is still gold colored.Bottom LineYes, I would recommend this to a friend.Was this review helpful?
