Customer Ratings & Reviews

Been using this liquid gold for well over a decade, also the other products as well. The process to place an order as well as status email updates, swift delivery..what more can one ask? I feel like I am using the Best motor oil for my vehicles. The cost of this product has always come at a premium, unfortunately, it seems more so in recent times.

Been with Amsoil for 14+ years and it's the best I've come across. However prices are getting out of hand and I'm wondering if it's becoming too high and the cost point isn't worth the improvement over other high performing motor oil brands that come at a fairly significant lower cost. Just not sure yet, but another price hike or two may just do it for me...

It all started when I used their double filter system when I used to drive for work 30 years ago. I was putting around 3k miles a month on my vehicle and looking to cut back on oil changes. I've been a fan ever since.

I have used Amsoil for years now and I have never been disappointed,great quality and American company 🇺🇸

I’ve been using Amsoil products for years and I will continue to do so. It is by far the BEST out there. Amsoil outperforms all other oil and oil products out there.

Have been using it for the past 120k miles with no problems.

I have been using amsoil for Years and Years, I don't use any other oil. I use Amsoil for all my Vehicles, including my StreetBike, Lawnmower, 4 wheeler, Pressure Washers, Anything I have that needs oil, Amsoil Goes Into it... 100% Loyal Customer!!

Amsoil is the best. Hands down. I've been researching ways to prolong the lifespan of all my motors. Royal purple isn't even a close second. Do your own research. Amsoil is king. ..... anyways, I was needing quantity, viscosity and oil filter for 2019 dodge ram 1500 5.9l hemi. 7 quarts and a win filter for a little over a hundred bucks, not a bad deal. I change mine every 10k. Premium gas and amsoil and you should get 300k miles outta your engine. We'll see.

great oil I change my oil once a year

Great product with fast shipping

I have been using this oil for over 20 years. Every vehicle I have used it in has never had any problems and it has increased the gas mileage.

I use only Amsoil's best in my high output 2.0 Ford. It puts out 400 HP and turns high rpms. It pays to use only the best.

I put nothing but the best in all of my vehicles, and Amsoil is by far the best. Scott Galbreath an employee of yours, has always been great to me and getting what I order quickly.

I send a sample to Blackstone after 16k miles on an 219k miles Acura tsx. Didn't add a drop of oil in thay time They told me will hold another 10k. Impressive. I have the report in case anyone wants to see it.

Excellent high grade oil

I’ve gotta oil consumption issue so use this oil there 5-w20 works the best for my 12 Acura TL and i always highly recommend this oil to anyone and everyone..?

Every time I’ve ordered products from Amsoil it’s been handled perfectly. Everything arrived ship very nicely. No problems at all. Very easy to use the website.

Had this tested at 5k. Results were almost the same as when new. This is good stuff!

Bar none the best oil on the market!

I've used all the commercial "synthetic" oils in numerous vehicles at my place of employment, and in my own vehicles. Amsoil Signature series by far holds up better during oil change intervals, especially in small displacement turbocharged engines. Other commercial brands become very black and deteriorated over the course of a service interval.
