    Best oil there is
    By  DAVID,  a  Verified Buyer  from  Michigan.   on  June 18, 2021
    Use this in a bunch of different cars year round. Works great! Quiets down the engine compared to name brand oils. Lasts longer, better wear results then big brands. Worth the money! Fantastic oil.
    Bottom Line
    Yes, I would recommend this to a friend.

    Great Lubricant in Winter and Summer
    By  JOSE,  a  Verified Buyer  from  CT  on  June 17, 2021
    I use this on a V8 that is supposed to get 10w-60 but I really don’t see a reason for it since that second number shears down fairly quickly. This is quite stable after a year. I only put on 2500 miles annually so it’s nothing.
    Bottom Line
    Yes, I would recommend this to a friend.

    Worth the money!
    By  Bellatrix.SS,  a  Verified Buyer  from  FL  on  June 17, 2021
    After using mobil1 for years, i noticed it wasnt lasting as it should and it would let the valvetrain make more noise. So i decided to try this in my freshly cammed L99 with a GPI VVT SS2 cam. Now, theres absolutely no valvetrain noise, my oil temps are actually lower, and my pressure is more stable. even on the hottest days i hold 28psi hot temp. Ill stick to using 8qt of this stuff from now on.
    Bottom Line
    Yes, I would recommend this to a friend.

    Jeeps Dream
    By  Bellatrix.SS,  a  Verified Buyer  from  FL  on  June 17, 2021
    Put this in the 3.6L pentastar in the jeep, and boy did she get quiet. mobil1 and valvoline would always let the top end sing its song. Now, Shes nice and quiet down here in FL.
    Bottom Line
    Yes, I would recommend this to a friend.

    2020 Tundra's first oil change
    By  CHRISTOPHER,  a  Verified Buyer  from  Michigan  on  June 15, 2021
    I wanted to put the highest quality oil in my truck and only changing it once a year was something I really liked. I changed the oil at 4,000 miles also used the Amsoil filter. Something that I didn't expect is that the engine runs better. It ran good before it's like new with only 4,000 miles. But the engine purrs like a kitten. It's amazing to me that oil could make that kind of a difference. I'm telling everyone.
    Bottom Line
    Yes, I would recommend this to a friend.

    Very good oil!
    By  TREVOR,  a  Verified Buyer  from  Sioux City, IA 51104  on  June 15, 2021
    Use this oil in all my vehicles except old blue which I use 10W-30 which is what the owners manual recommends. I think Amsoil is the top of the line in synthetic oils. Has protected my engines for a few years now.
    Bottom Line
    Yes, I would recommend this to a friend.

    Great oil
    By  Chowlee,  a  Verified Buyer  from  Sacramento  on  June 15, 2021
    My son had not kept an eye on his 94-F150 and ran it out of oil. I found it because the oil gauge dropped to 0 when I accelerated, then back up. After adding 9 quarts of oil it ran like a charm. 2 years later replaced transmission, but engine runs great. I swear by this oil.
    Bottom Line
    Yes, I would recommend this to a friend.

    Very good protection
    By  IAN,  a  Verified Buyer  from  Edmonton, Alberta   on  June 14, 2021
    I switched to the 10W-30 because my F-150 5.0L has always used oil and I’m trying to reduce oil consumption. So far it has made a huge difference over the 5W-20. I feel the 30 weight is definitely the way to go. Great oil !!
    Bottom Line
    Yes, I would recommend this to a friend.

    Clean
    By  MICHAEL,  a  Verified Buyer  from  Huntsville, Alabama   on  June 13, 2021
    Keeps my truck’s engine clean. I’ve noticed that as my engine gets older (113,000+) the oil I’ve consistently used in my truck has been free of burnt, or thick sludgy oil. My truck runs great, and I’m sure I’ll get another 113,000 miles out of her.
    Bottom Line
    Yes, I would recommend this to a friend.

    The cream of the crop! My favorite oil brand for Amsoil
    By  NATHANAEL,  a  Verified Buyer  from  New Jersey  on  June 12, 2021
    I know that no corners were cut in producing this high-quality oil. This oil has kept my engine happy and almost wear-free because of its chemical properties. I can't wait to do a partial tear down of my engine to see how well it performed because of performance upgrades. I will continue to purchase.
    Bottom Line
    Yes, I would recommend this to a friend.
