    Improved MPG
    By  mrdoow,  a  Verified Buyer  from  Stanwood WA  on  June 25, 2017
    2015 Mazda CX-5 purchased new. Car computer reported 24 - 26 average MPG. Switched to Amsoil at 32000 miles and experienced instant MPG increase. I have 10000 miles on Amsoil now and average MPG is 29 - 31. Considering the MPG performance increase after switching to Amsoil, I'd say the two years of free dealer oil changes was a money loser.
    Bottom Line
    Yes, I would recommend this to a friend.

    The best oil money can buy.
    By  Rick,  a  Verified Buyer  from  Phoenix, Az  on  June 25, 2017
    Years ago I read a synthetic oil life study. The study was very thorough, using different brands of oil, and filters. Amsoil came out on top. Another thing discovered during this study was shocking. Changing your oil increases engine wear. The oil changes we're done when the TBN reached a low level, and the first sample analyzed after the change always showed higher levels of wear metals. This abated by the second sample. My Subaru Forester is the first new automobile I've purchased. I need it to last a long time. I'm running Amsoil signature, and a bypass filter. I'm going to have the oil analyzed regularly, and base the change interval on the results. I hope it will last the rest of my life. I'm 63, so I've still got aways to go.
    Bottom Line
    Yes, I would recommend this to a friend.

    The quality is great and it lasts a long, long time.
    By  SDJazzMan,  a  Verified Buyer  from  San Diego  on  June 25, 2017
    I pulled into a gasoline station and they actually asked if I wanted them to check the oil. I knew it was okay but said - sure go ahead. When the attendant pulled out the dip stick I asked him to guess how many miles I had on that oil. He replied without hesitation and said that I had just changed it. When I told him that I had almost 5000 miles since I changed the oil, he couldn't believe it.
    Bottom Line
    Yes, I would recommend this to a friend.

    You can't go wrong using this oil
    By  The hobbiest,  a  Verified Buyer  from  Long Island, NY  on  June 24, 2017
    I change my oil every 15,000 miles because it has a 15,000 mile oil filter, I could go longer if amsoil made a 20-25,000 mile filter for my car. I use amsoil for my lawn equipment, motorcycle, and now to lube and clean my guns
    Bottom Line
    Yes, I would recommend this to a friend.

    Long-time user of Amsoil
    By  kirbstoy,  a  Verified Buyer  from  Mather, CA  on  June 23, 2017
    I know exactly how Amsoil will perform in my 2017, F-150, 3.5L/twin turbo. I have used Amsoil for decades and have never had an oil-related problem with any of my engines. Amazing chemistry...that's for sure.

    This oil must work well
    By  George,  a  Verified Buyer  from  Weirton, West Virginia  on  June 23, 2017
    I purchased a used 1996 Chevrolet C2500 with 341,000 miles on it. The previous owner said that he only used AMSOIL. So I drove the truck for a thousand miles then changed the oil with AMSOIL. It must work, the truck has the original engine, original transmission and the original exhaust system
    Bottom Line
    Yes, I would recommend this to a friend.

    Excellent Oil
    By  CJNREMTP@28,  a  Verified Buyer  from  Smithfield, NC  on  June 23, 2017
    This oil is spectacular! Somehow I failed to check the oil level in my wife's '08 Honda Accord 3.5L V-6 and when I did check it, it only had 2 out of the required 4.5 quarts! ; o I have not noticed any damage to the engine system since and count my blessings as she would have kicked my rear if anything would have happened to her beloved car! Thank you Amsoil for such an awesome product!!! You are a wifesaver!!! ; ) This idiot makes certain to check the oil level in her car now!!!!!
    Bottom Line
    Yes, I would recommend this to a friend.

    Great oil
    By  Chuck,  a  Verified Buyer  from  Florida  on  June 22, 2017
    Have used Amsoil for the past 15 years. During that time, it has never let me down. Early on, I had oil analysis done and the oil held up extremely well going over 20,000 real miles and still had life left. You can't ask more then that especially in a dusty environment.
    Bottom Line
    Yes, I would recommend this to a friend.

    Helps clean oil injectors
    By  Titsmcgee,  a  Verified Buyer  from  Little suamico, wi  on  June 20, 2017
    Have a 5.3 that I bought did first oil change and ran valvoline full synthetic burned 2qts in 2000 miles. On my 5 oil change with amsoil and burned 1/2qt in 3000 miles. 5.3 are known for burning oil due to oil injectors clogging but running amsoil seems to have made a huge difference.
    Bottom Line
    Yes, I would recommend this to a friend.
