    Greatest Oil and filter in the World
    By  KEVIN,  a  Verified Buyer  from  USA  on  August 06, 2022
    I was looking for an oil that would not wear out in the car after 3k miles. I tried many brands but I want to talk about AMSOIL. It was recommended to me by a race car driver, and I tried AMSOIL. Holy smokes, the best I have seen in my life. I change my oil now about every 12k miles and most of the time I do not have to change it then. The label states signature motor oil and the recommended miles. You can trust that comment. I even tried the oil in mower. It has been five years now of not having to worry about the mower either but I changed it anyway because it had been 5 years. I also noticed that other people where I live have to purchase new zero radius mowers every two years. I have been use AMSOIL in mine for over 20 years and have no worries on maintenance. The best oil does make a difference. I ask just give AMSOIL a chance and you will never have to worry again. My last car I only used AMSOIL in it, that car lasted over 800K. Please just try the oil, if you do not want that quality then go back to harming your mechanical equipment. If you want it to last us AMSOIL or prepare to have to replace the broken down mechanical equipment because you failed to protect it with AMSOIL. I really mean it. You should thank me for telling you but I care about your mechanical stuff and share the knowledge and best kept secret in oil. Kevin

    This is a great product ! I run this in my '18 F150. I have no issues. It does what it's supposed to do.! I use my truck as a daily driver + hauling 6k lb. Loads on average. I have been using AMSOIL for about 20 years now- I highly recommend it !

    Only the BEST for my Lexus!
    By  AirForceJohn,  a  Verified Buyer  from  Sarasota, FL  on  August 02, 2022
    I personally don't know all the brilliant scientific knowledge that went into a product like this, but I do a lot of research. My conclusion? This is the best motor oil on the market today to help meet my 300,000-mile goal on my 2015 Lexus RX 350. As a great bonus, my RX is averaging over 23 mpg in the city and 27 - 28 mpg on the highway. Way higher than the EPA estimate of 18/25 for this model.
    Bottom Line
    Yes, I would recommend this to a friend.

    Best oil on the market.
    By  MXrider,  a  Verified Buyer  from  Tucson AZ  on  August 02, 2022
    It's HOT here in Tucson, the heat dissipation of AMSOIL is amazing. If you don't believe me pull your dipstick out when your vehicle is hot and slide it between your fingers.. You can't do that with other oils. Heat kills motors. I driven numerous cars and trucks well over 250K miles with no issues related to lubrication.

    Great product from a great company
    By  STEVEN,  a  Verified Buyer  from  St Louis MO  on  August 01, 2022
    I have been a fan of Amsoil for a while. They have a top notch product, excellent customer service and competitive pricing (when you subscribe). I can reach out any time with questions, the products arrive fast, and my cars and trucks/keeps seem to run better with it. For the extra protection and peace of mind, it is worth the slightly higher price. I just performed an oil change and differential changes. Next is transfer case and tranny… my gladiator and I thank you for a great product line!

    Yes, I would recommend this to a friend.

    Great Product and Even Better Service
    By  James,  a  Verified Buyer  from  MN  on  August 01, 2022
    I figure if Gail Banks and the people at Motor Trend are using the stuff ya pretty much can't go wrong. I have used Amsoil in the past and have always been happy with it. Went back this time because when 87 octane hit $4 a gallon I shifted to E-50/E-87 and I wanted the quality and extra protection. And talk about service. Received my order the following day. Didn't expect that at all.
    Bottom Line
    Yes, I would recommend this to a friend.

    Good for 106K miles so Far
    By  DOUG,  a  Verified Buyer  from  Calif.  on  July 31, 2022
    We use this in my college sons 2010 Camry with 106K on it. Was my Wife's before we upgraded her in to a newer car. Been using it since the 1st oil change on the recommendation of my Amsoil Rep. The car has been trouble free engine wise and you all know how hard kids can be on cars. My son has the understanding that there are no replacement cars for him and he needs to take care of it for the rest of college and beyond. This is inexpensive insurance for me. I also run Amsoil synthetic oil in my 20 year old Ford Superduty with 234k on it so far, again take car of your equipment and you will be rewarded with great service from them. I recommend Amsoil Products...

    Hands down best oil
    By  MIKE,  a  Verified Buyer  from  Florida   on  July 30, 2022
    I am constantly running the road for work in Tundra and went from changing my oil every 5k to 10k. Even when I change it after 10k it’s still that fresh brown and never seems to break down like conventional oil. The break down of thi

    Top of the line
    By  DAVID,  a  Verified Buyer  on  July 29, 2022
    I have been using Amsoil since purchasing my SRT8 Challenger in 2010. I did a lot of research & went with the first & the best in the synthetic oil business. I started with the regular full synthetic Amsoil & have been using the signature series for about 4-5 years now. I change my oil once a year regardless of mileage. In HP applications especially, why not put in the best there is.
    Bottom Line
    Yes, I would recommend this to a friend.

    Fantastic oil
    By  TDC,  a  Verified Buyer  from  WI  on  July 28, 2022
    I switched my truck at 165k. The first oil change I burnt through 3 qts (out of 8qts). AMSOIL explained the high level of detergents we’re cleaning my engine. Mind this truck NEVER burns oil, ever. The next oil change 15k later the oil consumption stopped. I wanted AMSOIL for the convenience of 15k change interval. What I happily found was my mpg went up 1.5 mpg, from 15.5 highway to 17mpg. Pulling our trailers mpg went up .5mpg but I haven’t pull extended highway miles yet just 1hr to 2hr jaunts. This past winter the truck sat out in -45F over night multiple nights and fired up right away …. My old synthetic required extended cranking but always started on first try. With AMSOIL it’s instantaneous. We have 4 cars/trucks …. They’re all going 100% AMSOIL. I’m a believer.

    Yes, I would recommend this to a friend.

    The oil is free since my car runs forever
    By  TONY,  a  Verified Buyer  from  Palm Harbor, Florida  on  July 28, 2022
    My 2004 Ford Expedition 4.6 V8 has 214,000 miles and runs like new as I only use Amsoil. My last 1998 Expedition also had over 200k miles before this one. I would consider this oil free since my gas mileage is increased and I can drive my autos as long as I want. My friends Volvo turbo bearings were rattling and I put about a half of quart of my Amsoil in it and the turbo bearing quit rattling.
    Bottom Line
    Yes, I would recommend this to a friend.
