Customer Ratings & Reviews

Just having Amsoil in my truck is a huge relief knowing that the engine is protected with the Industries top leading oil hands down.

Excellent product! I changed from using mobile one for 2 years, and immediately I felt the difference in how the car ran overall. I have an rsx type s, so it’s high revving. Before it almost felt like it was struggling, but now it drives at 3-4 thousand rpm like its supposed to. You can feel how free the engine operates. Thankyou amsoil!!

I love the fact I don't have to guess using there vehicle selection process. My oil change was really easy.

I use to find other manufactured 5W50 full synthetic oil at my local auto parts stores, but no longer. Glad I checked the Amsoil website. 5W50 gives my '73 455 Pontiac immediate lubrication on cold start then thickens up just right when driving it hot. Very glad I found it. I will be purchasing Amsoil always for this vehicle and my boat; which I take out onto Lake Superior. So please do not stop making it. The website, purchase, delivery were all good experiences.

I've been using different Amsoil oil for my car my Harley, Amsoil technologies are specialized in oil quality. I drove one of my car for over 300km the compression was still in the 95% spect. The only oil I trust is Amsoil they test there oil on a third-party for velocity and the result are provend top quality.

Trust only Amsoil products for all my vehicles. Motorcycles, quads, snowmobiles, truck and cars. They all get the Amsoil treatment!

Change over all my autos over to Amsoil this year. Working great!

I’ve been rocking this oil on my F150 3.5 EcoBoost since day one. All I can say I’ve never experienced any issues with that engine. Also I can attest that my MPG is really good

Use this on my Chevelle with an LSA engine. Works great. No oil consumption, quiets engine and just performs great overall. Ditched another brand made specific for LS based engines (not worth it and doesn’t perform like Amsoil). I’ll continue to use Amsoil from here on out.

I switched to full synthetic in Ford 5.4 engine a couple of years ago and it is still working great so far. I have only 135000 miles on it but it has the death tick so I know that it’s a matter of time. But Amsoil keeps it going.

I started using Amsoil in my 2005 GMC 2500 at about 65k miles. I was changing every 15k miles with no issues, and when I hit 160k lowered my interval to 10k. At my most recent oil change my mechanic said the old oil looked great. I will continue to use Amsoil in this vehicle and my next.

My 2016 Toyota Tundra crewmax 4x4 gets run hard. The heat in Florida combined with towing a trailer with 4 ATVs on it or towing my boat beats my truck down, but my amsoil 0w20 stays strong and performs amazing. Would definitely recommend.

My wife's car runs so smooth with amsoil. Her 2015 Hyundai Elantra was bought new and has had amsoil since the first oil change. Absolutely love it.

I'm satisfied with the performance of my 3.5 Penstar at 82000 miles and no problems which I attribute to a great engineered motor and AMSOIL.

Wouldn’t use it if it didn’t work as advertised!

Oil doing great, I’m on the 0-40 weight and did great on my 2,600 miles from Florida to Oregon in the summer peak month. Previously I was using AMSOIL in a different car and also did great in the deep winter in Chicago at -40 and started at ease versus other oil brands the engine would feel the viscosity is sub zero temperatures. cold climate

This oil ROCKS! In the harshest winter condition it facilitates easy starting in temps -30F. In the summer with 100F it maintains proper oil pressure. My last vehicle , (Hyundai Elantra, 2011) passed 425,000 without a single engine repair! I recommend this oil... when considering value... nothing else even comes close!
