    Best street oil
    By  Christopher,  a  Verified Buyer  on  December 12, 2016
    Use it in my 06 Pathfinder and 14 Evo X. Great cold start up and even better protection once hot. Viscosity breakdown is almost non-existent. I have been using AMSOIL for years in engines, transmissions(where applicable), transfer cases, differentials, and firearms. Actually, my Evo X tuner(renown CBRD in York, PA) told me to use AMSOIL. Great products.

    HUGE difference
    By  Richard,  a  Verified Buyer  on  December 11, 2016
    This oil and filter made my 5.7L V8 Toyota Tundra a whole other animal! Engine definitely runs smoother than the last 240k miles I did on it and I have noticed about a 1mpg gain. I also noticed a smoother acceleration and a bit faster too! If u want a long lasting a smooth running engine then this is definitely the oil for you.

    I would definitely buy this product again !
    By  Leo,  a  Verified Buyer  on  December 11, 2016
    The turbocharged engine in my car is very picky on oil, and AMSOIL is one of two brands that I had been using. As the local stores here so not stock Amsoil anymore, I purchased online and it was a great experience - lightning shipping and product as ordered. Thank you so much again, Leo.

    Toyota Tundra
    By  Leon,  a  Verified Buyer  on  December 07, 2016
    Bought a new Tundra for the wife. When due for the first change I went wild and changed it all to amsoil. I believe this coupled with CAI is what gave us the 1.5mi gas increase!! Plus always better with the piece of mind I get with my amsoil products.

    Amsoil Products are second to none
    By  Mad Max,  a  Verified Buyer  from  Weaverville NC  on  December 01, 2016
    I've been using Amsoil since 1989 when I use to race snowmobiles in the north east the product never let me down. I used Amsoil in motorcycles, 4 wheeler and side by side again this product came through no matter what abuse I put my toys through. I've recently got into cars since my move to NC I have 2015 Mustang GT that's pushing 703 RWHP AND 600 FPTQ to the wheels from past experience with Amsoil the only oil for my ride would have to be Amsoil. I ran a (153) 1/2 mile in Clayton GA at Heavens Landing this year and plan on taking the car in March to the Texas mile. Amsoil is so much more than oil I use there anti freeze, gear oil, octane boost and much more. The Staff is outstanding, the shipping to your front door is insanely fast and well packaged. Thanks Team Amsoil for a great 27 years and hope to have many more ahead of me.
    Bottom Line
    Yes, I would recommend this to a friend.

    First time running Amsoil
    By  Mechghy78,  a  Verified Buyer  from  New Waterford Ohio  on  September 19, 2016
    I changed to amsoil from gm dexos as I wanted something better for my Cruze. After 10k of running dexos as it was included with the car, I switched to amsoil and immediately noticed the engine running quieter than with dexos. I am happy with the change so far and am looking forward to see how it holds up as I only have 1500 miles on it so far. We'll see what happens when I get into my second oil change.
    Bottom Line
    Yes, I would recommend this to a friend.

    Would use no other oil.
    By  Southern Wolf,  a  Verified Buyer  from  Ruskin, Fl  on  September 15, 2016
    I have been using Amsoil in three of my vehicles now. One I sold with about 280k miles and it did not use any oil. As soon as I got my new car home I change out the factory oil to Amsoil. I have a Jeep Wangler that I put a performance Chevy 350 in., 340 hp 390 ft lb torque. I have had over heating problems with it and have driven it all day with temps over 230. The oil did not cook and I still don't use oil, I've put over 60k on this engine using the Z Rod oil.
    Bottom Line
    Yes, I would recommend this to a friend.
