Customer Ratings & Reviews

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 !

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.

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.

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!

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.

Fast Service

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...

it comes a little under full of the one liter mark

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

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.

Superior product. Simply the best oil . It stays clean for a very long time. Way better than most other oils .

Superior product. You will be amazed at how clean your oil will stay . It's simply alot better than any other oils out there.

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.

I’ve been using this oil for my vehicles for the peace of mind, knowing that the engine is protected far beyond OEM requirements.

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.

Use nothing else. Although their shipping cost is out of control I still order.

Yes I would recommend this to a friend

No oil can compare to Amsoil. I don't cheap out when it comes to what I put in my Lexus. Everything runs so smooth, and feel great knowing my engine is protected using Amsoil. Price is worth, the quality and protection.

Since I switched from Mobil 1 to Amsoil I have noticed that my vehicles run smoother and quieter. It has to be because of the superior oil adherence and lubricity.

Awesome product. Switched my Vette to Amsoil after watching my buddy race his for 2 years without any issues. Superior protection, runs smoother and cooler. Looks cleaner than Mobil 1 after 5k miles. So impressed I switched both my Colorado 4x4 and the Traverse AWD HighCountry to Amsoil.
