    Wonderful
    By  CAMERON,  a  Verified Buyer  from  Utah  on  January 18, 2024
    I love this oil. I've been using it in my 2010 370z, it's a daily and a track car. I was not expecting to feel such a difference when switching from Mobil 1 to this signature series. And my over all oil temperature stays below 200° before it would sit right around 240°
    Bottom Line
    Yes, I would recommend this to a friend.

    Smoother idling
    By  BRIAN,  a  Verified Buyer  from  Connecticut   on  January 18, 2024
    2021 Malibu ran better right afterwards. Idles better, accelerates better, sounds better. I knew with a turbocharger, I had to use the best. Used Valvoline synthetic before switching over. Will never use anything else again..
    Bottom Line
    Yes, I would recommend this to a friend.

    By  Wick ,  a  Verified Buyer  from  Elizabeth City NC  on  January 17, 2024
    Awesome products and was using Royal Purple until introduced to this and I now ask myself “Why Didn’t I Switch Then” but after switching and reading all the information comparison charts and end results I will never use anything else but AMSOIL. Great OILS !!!!!!

    Expensive but worth it
    By  drpete82,  a  Verified Buyer  from  Kansas City MO.  on  January 17, 2024
    Had been using Pennzoil Ultra Platinum in my 2020 Tundra but after 4-5k miles on the oil I would start to hear a ticking noise which is common with these engines. I believe it’s the lifters. I switched to Amsoil oil and filter and have close to that mileage on the oil change, but this time no tick. Will continue to use Amsoil.
    Bottom Line
    Yes, I would recommend this to a friend.

    Best Products I have used in my Toyotas!
    By  David,  a  Verified Buyer  from  Montana  on  January 16, 2024
    I use Amsoil filters in conjunction with Amsoil Signature Series 0w-20 motor oil in a Tundra, Sequoia and a Rav4. I have had my oil independently tested at intervals to 10k miles. The tests results convinced me this combo is nothing short of fantastic! Blackstone told me I could exceed 10k miles on an oil change interval......enough said!
    Bottom Line
    Yes, I would recommend this to a friend.

    Oil looks gray engine feels great
    By  REI,  a  Verified Buyer  from  High desert So Cal  on  January 16, 2024
    Chevy Traverse 2019 engine oil change and filter. Well all I know is that it’s clean, feels like good quality and doesn’t spill. As far as the oil, I put 5.5 qts as it requires six I’m sure there’s oil still in the engine ajuste chillin in there so after filling, dipstick showed it was at the right level. The engine does make a different sound on start up. Possibly the oil difference. I will try one more time possibly at 8 k and not the 20k it recommends.
    Bottom Line
    Yes, I would recommend this to a friend.

    Big Fan of Amzoil
    By  BLAIR,  a  Verified Buyer  from  Rhode Island  on  January 15, 2024
    Big Fan of Amzoil because of the extended oil change. Back in the 1990's I was working in the racing industry (SCCA) on the weekends. What that meant was an average of 30,000 to 40,000 miles of driving and working 80 to 100 hours a week during the racing season. I never had an engine problem was running Amzoil. A mechanic that worked in the industry could not believe how nice the engine ran for the mileage on it and how good it looked inside. He started using it right away too.

    1st time use=Lifetime Customer
    By  MICHAEL,  a  Verified Buyer  from  Kentucky   on  January 15, 2024
    Great Product, I put in my 2018 GMC Sierra 1500 Denali 6.2L 51k miles and the motor couldn't be happier plus me. The motor temp before ran a solid 210 degrees now 160-190 interstate travel. Average 4 hr drive at 85 mph it only heats up to 180-190 AMAZING without pulling a load. If driving around town or short interstate travel 75mph or below 160-170. The motor feels like it turns easier. I'm so pleased I'm getting ready to switch my backup vehicles oil to AMSOIL... I'D RECOMMEND TO CLOSE FRIENDS OR FAMILY WITHOUT A DOUBT... Thanks AMSOIL I wasn't paid or compensated for this review..
    Bottom Line
    Yes, I would recommend this to a friend.

    1st oil change
    By  DAVe,  a  Verified Buyer  from  Edgewood, Washington   on  January 15, 2024
    I’ve been a true believer in AmsOil since 1975. First used it in my new Kawasaki 900. I trusted it then as I do today. I just dropped the factory oil in my 23 F150 Coyote 5.0 could be the power of positive thinking but…I swear it runs noticeably quieter with this oil. As long as I can change oil it will be AmsOil for sure
    Bottom Line
    Yes, I would recommend this to a friend.

    Carburetor on my Harley Davidson told the story.
    By  TERRY,  a  Verified Buyer  from  Warner Robins Ga  on  January 15, 2024
    I was won over with Amsoil in 2003 when I changed oil in my 2003 Harley Davidson that has a carburetor. You can learn more about a motor with a carburetor, the throttle, the click, the run, the function has more of a personal touch. The shift in the sound and the throttle response told me all I needed to know about Amsoil. I use in all five of my vehicles. Engines last longer and run at optimum levels.
    Bottom Line
    Yes, I would recommend this to a friend.

    Definitely recommend Signature Series 0W-20
    By  CLAUDE,  a  Verified Buyer  from  Ontario, Canada  on  January 14, 2024
    My 2.6L 2017 Mazda 3 engine idled much more quietly after the oil change. Amsoil Signature Series 02-20 replaced Mazda Service's 0W-20 that had gone 15k < 1yr. Engine is working great. Highly recommend Amsoil. (My oil filter is now an Amsoil).
    Bottom Line
    Yes, I would recommend this to a friend.

    Amsoil is the best on the planet
    By  DAVE,  a  Verified Buyer  from  Wilmington, Delaware  on  January 14, 2024
    This is the only oil I use in my 2010 bmw 335i my car has upgraded turbo’s and it’s producing close to 500 hp at the rear wheels. I have noticed the engine runs smoother and quieter, and when I do oil changes 3K in this car, the oil is much cleaner than the last oil I was using. It is a little more expensive but it’s well worth it along with all the products that they sell..highly recommended!!!
    Bottom Line
    Yes, I would recommend this to a friend.

    Lab Results Prove Best!
    By  STEPHEN,  a  Verified Buyer  from  Appalachian Mountains, NC  on  January 14, 2024
    Use to run Motul in my 2003 Subaru WRX for years. Bought a 2018 Subaru Type RA and continued the Motul. Local inventory was running low so I tried Amsoil Signature Series. I still had enough Motul for 2 oil changes so I ran the Amsoil for 3,000 miles then Motul for 3,000. Took several months of back and forth with lab results every oil change and the results proved Amsoil did slightly better than what I previously thought was the best. Wear metals down slightly and overall viscosity was higher! And this was through the hard running summer months when I run Tail of the Dragon every weekend. For those not familiar it's 318 turns in 11 miles and way harder on the car than any track day. Nice to know I'm now protecting both my Soobies with the very best...lab proven! Thanks Amsoil!!
    Bottom Line
    Yes, I would recommend this to a friend.

    By  KEVIN,  a  Verified Buyer  from  Athens Alabama  on  January 13, 2024
    I drive 1000 miles a week, so I rack up a lot of miles on my cars. I put 300,000 miles on my last car with the original engine and transmission. Nothing but Amsoil for me!

    Yes, I would recommend this to a friend.
