    Excellent product
    By  JOHN,  a  Verified Buyer  on  March 21, 2023
    I've used Amsoil in multiple vehicles and in all weather conditions. I like it for cold starts and on extremely hot days. I would like to see more free shipping incentives (lower purchase amounts) and the prices are quite a bit higher than Mobil 1 extended life. You might lose some clients.
    Bottom Line
    Yes, I would recommend this to a friend.

    Synthetic Is The Way
    By  CHAZZ,  a  Verified Buyer  from  Oahu  on  March 20, 2023
    I have successfully switched all my cars over to AMSOIL. I love that you have the option to order the oil change kits which come with the necessary amount of oil and the required filter. This takes the guessing out the oil change.
    Bottom Line
    Yes, I would recommend this to a friend.

    Amsoil Signature Motor Oil
    By  JOHN,  a  Verified Buyer  from  Long Island, NY  on  March 20, 2023
    Been using this liquid gold for well over a decade, also the other products as well. The process to place an order as well as status email updates, swift delivery..what more can one ask? I feel like I am using the Best motor oil for my vehicles. The cost of this product has always come at a premium, unfortunately, it seems more so in recent times.
    Bottom Line
    Yes, I would recommend this to a friend.

    Best Oil Comes At HIghest Price!
    By  DOUGLAS,  a  Verified Buyer  from  Dumfries, VA  on  March 20, 2023
    Been with Amsoil for 14+ years and it's the best I've come across. However prices are getting out of hand and I'm wondering if it's becoming too high and the cost point isn't worth the improvement over other high performing motor oil brands that come at a fairly significant lower cost. Just not sure yet, but another price hike or two may just do it for me...
    Bottom Line
    Yes, I would recommend this to a friend.

    The best
    By  JIM,  a  Verified Buyer  from  OH  on  March 20, 2023
    It all started when I used their double filter system when I used to drive for work 30 years ago. I was putting around 3k miles a month on my vehicle and looking to cut back on oil changes. I've been a fan ever since.
    Bottom Line
    Yes, I would recommend this to a friend.

    Everything i needed for 2019 5.9L oil change
    By  EVAN,  a  Verified Buyer  from  Cocoa, Fl  on  March 19, 2023
    Amsoil is the best. Hands down. I've been researching ways to prolong the lifespan of all my motors. Royal purple isn't even a close second. Do your own research. Amsoil is king. ..... anyways, I was needing quantity, viscosity and oil filter for 2019 dodge ram 1500 5.9l hemi. 7 quarts and a win filter for a little over a hundred bucks, not a bad deal. I change mine every 10k. Premium gas and amsoil and you should get 300k miles outta your engine. We'll see.
    Bottom Line
    Yes, I would recommend this to a friend.
