Customer Ratings & Reviews

I have tried many oils for my trucks, including the Royal Highness lol but honestly Amsoil has been the best I currently have 200,000 miles on my 2020 jeep and I truly believe the oil is keeping the engine running stronger then ever. I will continue to run Ams and constantly recommend it

Great stuff

I have been using AMSOIL products for close to 20 years now on all my vehicles (Ford P/U Trucks, Jeeps and Harleys). My vehicles just seem to run better. They run cooler, shift smoother and get better MPG. And when I do an oil change, I get almost every drop back in the used oil catcher. And to make things even better, ordering from the AMSOIL web site is super simple. Easy look-up for your particular vehicle, save your vehicle(s) in the 'Garage' for future use, package deals, and super-fast shipping. I can think of nothing negative to say about the entire experiences that I have with AMSOIL over the many years that I have been using their products and dealing with the company as a whole. THANK YOU!

Great product protection for the engine

If you’re shopping Amsoil, you already know it’s the best oil out there. Easiest customer service to deal with and fastest delivery… AND I didn’t leave the couch to do any of this. Highly recommend anything Amsoil sells.

I’ve used this oil for two years and recently had it tested after 11,000 miles. Testing showed this oil to be in great condition, no metal and chemically still strong.

After intense research on all oils only amsoil finished 1st. Most synthetic motor oil only are 10 to 20% synthetic Amsoil is almost all synthetic over 80 % It stands alone as the best motor oil for your vehicle by far

Great oil. Using it on two of my vehicles. Gas mileage improved and since switching a few years ago, I find that my oil levels stay consistent with less evaporation or burnoff versus Mobile or Penzoil Full Synthetic oils.

I’ve been using your oil and other products for over ten years,now two my sos do as well. Great company.

I have been using Amsoil in all of my vehicles for years. 2007 Toyota Tacoma with 335,000 miles runs like it is new, 2010 BMW 528 with 145,000 runs like a top and last my 2005 Ford F250 Diesel with 265,000 runs great. Simply put all 3 of my vehicles run great, have never broke down and it is because of regular service and Amsoil. I also use it in all my lawn tools and lawn mower. Simple-it’s the best !!

Absolutely the best oil I have ever used. It is everything it was advertised to be and more! Nothing on the market even comes close to the quality! Job well done!

Great product. There is a reason why people pay as little more and wait for the shipping (which is a couple days at the worst). I will continue to use this in every engine I have

Use this one both of my lexus is300's. My daily had over 300k and my fun one had 150k.

I purchased my AMSOIL products by word of mouth testimonial from someone who I trust concerning topics such as automotive care, and they were right! My 2006 Nissan Frontier 4.0L is experiencing a rebirth in fuel economy! It's always been a great little truck, but since changing over to your product I believe that my engine is not working as hard as it was, and it has 207,000+ miles on it! Thanks Amsoil, I'm telling family and friends about it!

Very happy with Amsoil products.

I run this in my wife’s Kia that has close to 200,000 miles on it now. The engine doesn’t burn any or or make a sound. This oil has been great!

Changed oil on my 2014 Subaru forester, has 86,000 miles. Running great.

Switched to Amsoil for the price and reviews, change oil at 7k and still looks clean

Unfortunately I could not use this product, I bought a new truck before the oil change was due and now it's just sitting here

Ive noticed a little better oil pressure on my 18 Silverado 5.3 ,it calls for 0w20 oil and I personally think the 5w30 higher mileage works better for the hot Illinois summer's that we have and I've cut my oil filter apart and there always clean .
