The best oil ever. I wish they had more swag to send

Awsome....truck K is running like the first day I got it.........u guys are awsome customer for life

I've been using AMSOIL products for all my vehicles for 20+ years. Boat and motorcycle for a little less time. I love the extended oil change intervals. When I order supplies, they generally arrive at my residence within 2 days and sometimes the next day. Not sure how they do that, but they do. I've never had any issues and my confidence in their product line is noteworthy. I've used Signature Series on primarily on GM and Toyota. The difficult part is sometimes seeing the oil level on the dipstick as this maintains clarity for an extremely long time. I avg approx 15K miles/year. I highly recommend.

I have been using Amsoil for decades and have been using it in all my vehicles. Never had an issue with Amsoil, and believe that they have top quality products. It is best to be a member to get the discounts in price and shipping. Will continue to use Amsoil in my vehicles in years to come.

This product deserves recognition!! I have used it on my last 4 cars that totaled a million 400k One had 475k this one has 370k still running strong! Awesome is all I have to say!!!!

I have been using this motor oil since my GMC Sierra was new. My truck is a 2018 with the 6.2 engine.

This is the best oil to run in any engine it holds up against high heat and very cold weather. And the oil last a very long time. I will never leave Amsoil this will be the only oil I run in any vehicle or bike I have

Amsoil is the best synthetic oil out there. Less resistance, car drives faster now too!! Highly recommended oil to get!!!!

Best oil on the market will use in all my vehicles and equipment

Best oil there is. Makes an engine run smoother.

The viscosity seems to be holding up . Don’t really know since it’s only been a couple of oil changes .

I have used AMSOIL in Texas for over 20 years. It has served me well with long intervals regardless of filter used.

0W-30 oil is a rare commodity in oil offerings. Oil Forums, FB pages are constantly debating the oil issue 0W-20 vs 5W-30 on new vehicles. I understand the 0W weight for cold starts, especially in Montana. However, I also like the 30 rating for towing and turbo engines. I’ll be validating my theory with Blackline oil tests over the next year. I may opt for 5W-30 when Montana summer temps hit.

Our 2008 Toyota Highlander has over 227000 miles on it and still does not need to have oil added between oil changes. Never run any other oil from when we bought the car with 9000 miles on it.

As someone who drives a 24 Civic Si daily, enjoys spirited driving, racks up highway miles, and explores the best curvy roads of the Appalachians, you’re asking a real enthusiast’s question, not just “what’s good oil?” but what oil protects and performs under real-world stress. In that context, AMSOIL Signature Series 0W-20 stands out as one of the best choices on the market

It's motor oil.

I have a 2011 Ford Taurus. I use Amsoil because its a liquid insurance policy for my Ford's engine.

Received oil and filter package super quick. They were packed well. Paul Archer is my sales representative and he has been great to work with. Highly recommend Paul and Amsoil! Thanks

The order was received in excellent condition.

I run this in my 2019 5.0 F-150 and the results honestly surprised me. Before switching, my truck would burn a noticeable amount of oil between changes. After running Amsoil Signature Series, consumption dropped significantly. I also sent a sample to Blackstone Laboratories at 7,000 miles, and the results were impressive. Wear metals came back lower than the universal averages — and those averages are based on about 5,200 miles of use. They even noted I could safely run 9,500–10,000 miles before needing to change it. Between the reduced oil consumption and the strong oil analysis results, I’m completely sold. It’s not the cheapest oil out there, but the performance and protection speak for themselves.
