    Made a believer out of me!
    By  LARRY,  a  Verified Buyer  from  Indiana  on  May 14, 2024
    My 2003 Dixie Chopper lawn mower came with a BP90 Amsoil bypass filter. The mower is 21 years old and runs as good as when it was new. I feel like the bypass filter has saved me a lot of money in not having to by a new motor or mower because of a worn motor!
    Bottom Line
    Yes, I would recommend this to a friend.

    Three Tow Trucks Loves These Products
    By  PERRY,  a  Verified Buyer  from  Gatlinburg, TN  on  May 08, 2024
    I have had the Dual Filter system on 3 GMC Pickups that towed my 10,000 pound Airstream all over all the Lower 48, most of the Canadian Provences, two summers in Alaska, and two summers in Newfoundland. For several years I always sent oil off for testing when I changed the oil at the end of the year, and never got a report stating I needed to change the oil. I no longer send oil off for testing, and have never had a problem. I Chang the full floe filter twice per year, and the Bypass filter once per year, and always use the top quality Amsoil at the time. My last two trucks have been DuraMax Diesels, one of them now owned by a friend now has over 200,000 miles on it, and still pulls his travel trailer all over. It still follows my oil change program, I supply the oil and filters for the truck.
    Bottom Line
    Yes, I would recommend this to a friend.

    Cummins 6.7 bypass filter
    By  RICHARD,  a  Verified Buyer  from  Texas  on  April 09, 2024
    What a difference this has made in the oil quality. 2 microns vs. 20 microns of filtration makes a huge difference. With the cost of oil and filters today this will allow me to extend my change intervals. I should have the return on the investment in 2 oil changes, not to mention the overall protection of my engine.
    Bottom Line
    Yes, I would recommend this to a friend.

    Bypass filter set up sturdier than expected and easy install
    By  CHRIS,  a  Verified Buyer  from  Boston  on  March 13, 2024
    Put a super charger on my car and just thought the best oil for my engine would be a good idea. Tried it on a whim and the install only took a few hours. Was concerned about introducing leaks to the oil system but the unit is so stout and of such high quality, there are no issues at all. Just make sure you order the right adapter and right filters for that set up. I was sure I had it right from the chart but after I emailed Amsoil they clarified the correct adapter. You do not use the normal cars oil filter anymore. You use larger and better filters that fit the bypass system. You oil is being constantly cleaned by the low micron bypass filter, really good. I would recommend getting the sample tap off valve just so you can easily check the oil. Time to change the oil, let be check, WOW completely golden brand new looking oil when I pull if off the tap. Just really nice to see how well the system is. When I do decide to change the oil, that still golden oil is great for all my yard machines; Lawn mower, compressor, edger, snow blower, etc. I had the oil tested and they asked why I was testing new oil. No breakdown of the oil at all. If you want to protect your engine and keep your expensive synthetic oil clean this is the way to go. The oil does not really breakdown, it just gets dirty with the abrasive carbon blow by. If you are thinking about a bypass filter this is the way to go.
    Bottom Line
    Yes, I would recommend this to a friend.
