    #1 option for my new Ranger Raptor 3.0L Eco
    By  SCOTT,  a  Verified Buyer  from  Tacoma, WA  on  November 25, 2025
    Did my first o/c at 1,000 miles & then again at 3,000 on my new ‘25 Ranger Raptor with the 3.0L Ecoboost and instantly switched it to AMSOIL 5w-30 full synthetic and that’s all this engine will ever get from here on out. Now I’ll settle into 5K intervals. Cheap insurance as I do it myself. Had nothing but success with this oil on my last 2019 F-150 with the 3.5L Eco. These twin turbos engines are synonymous for reacting negatively with the cam phasers & whatnot to low quality & dirty oil and low maintenance. Followed the same 5K routine and used the same AMSOIL and when I traded that F-150 in on this Ranger with 135K I had never as much as had an ounce of engine or cam phasers rattle troubles. So I never considered any other oil brand options. Returned back to what has already proved itself to me. AMSOIL.
    Bottom Line
    Yes, I would recommend this to a friend.

    Great product but very expensive.
    By  JEFF,  a  Verified Buyer  from  USA  on  November 25, 2025
    I’ve got a 2020 Subaru WRX. I use to use Mobile 1 -I like to drive fast the car wants to be driven fast. Mobile 1 wasn’t holding up well. I was only getting 2500 miles per Oil change. Amsoil came highly recommended so I’m gave it a try. -The ride feels very smooth now. YOUR GONNA PAY FOR IT. - It’s a very expensive product, this is my first time using it, I hope it delivers, if so I’ll be a fan for life.
    Bottom Line
    Yes, I would recommend this to a friend.

    Best oil on market
    By  KEVIN,  a  Verified Buyer  from  Kentucky   on  November 25, 2025
    I had purchased this oil for my built 2012 Camaro ss. The difference in protection compared to other oils is unparalleled. There is no better oil on any market than amsoil. I will continue to use it at all my oil change intervals. And will recommend it it all my family and friends. And to anyone I speak with. Thank you all for making a great product that anyone can feel safe to use for any of there automotive projects.

    By  STEVEN,  a  Verified Buyer  from  NC  on  November 23, 2025

    Your number 1 in my book
    By  NELSON,  a  Verified Buyer  from  QUEENS ,N.Y.  on  November 22, 2025
    Some might say this oil is a little expensive , But it's not . I used to change my oil every 3 months with other motor oils. now I change my oil every 6000 miles. I actually save money on extra trip to mechanic and oil filter. I know my motor on my ford E350 box truck is getting the best oil and detergents .Shipping is just as fast as when I order items from Amazon.. Thank you Amsoil, I am please and have even told of this number one oil and it's great customer service. Happy Holiday Everyone

    Always good
    By  ANTHONY,  a  Verified Buyer  from  Maine  on  November 22, 2025
    Just like with my diesel, any gas vehicles I service get the signature series synthetic if the customer asks. Tests out just like my personal diesel truck using the 5W-40 signature series diesel oil -- very well.
    Bottom Line
    Yes, I would recommend this to a friend.

    Best oil change experience I've had
    By  MARK,  a  Verified Buyer  on  November 18, 2025
    I heard good things about AMSOIL and I decided to give it a try. The whole oil change package came professionally packed and had several useful items that they included that I wasn't expecting. Provided with the oil was a spec sheet that outlined all of the data on the oil and the micron of the filter. With the membership the cost was negligible compared to a standard oil change from an auto parts store and I can rest easy that I am maintaining my truck with good quality oil.
    Bottom Line
    Yes, I would recommend this to a friend.
