Customer Ratings & Reviews

I've used Amsoil products for years. If you understand the product technical reports, You will use this oil and filter combination. Best for wear, cleaning and longevity I've ever found. Lubricity is second to none.

Use in both personal and now work vehicle. Can't go wrong with extended drain intervals, pays off fast.

This oil has made a noticeable difference in my hemi. It's made the engine quieter and given me better overall gas mileage. You can't go wrong with the right oil.

I always order signature series for every oil change on all my vehicles and very been disappointed with the protection.

Of course anyone who has done any research on motor oils realizes that AMSOIL motor oils are superior to anything else on the market. I like all their products however I am upset at their recent price increases. I'm not sure why they continue to raise prices as the majority of us retired people never get a cost of living increases in our income. Please don't tell me it's R & D or material and labor increases to justify the increase.

I run amsoil in every motorized vehicle I own...very happy with all products

I have been using Amsoil products for over 30 years I believe they are the best

I use Amsoil on all engines large and small. Top in its Class

So far so good. No problems. AMSOIL has came highly recommended from my research. I plan on keeping my vehicles for the long haul and it made sense to step up to a better oil for my 2015 silverado 1500 z71 and lexus rx350, both of which use the same oil.

I started using Amsoil several years ago in my 2-stroke YZ125 and was very impressed. Back then I was rather unfamiliar with Amsoil so I started doing some research on Amsoil and other competitor brands, because I only wanted to run the best lubricants in my equipment. What my research uncovered for me is what I now believe to be so great about Amsoil. Amsoil provides plenty of literature from third-party testing that truly separates their products from the rest of the field. Other brands will only tell you what they want you to hear, but what is great about these testings is that we as customers can see for ourselves side-by-side test results, and the results speak for themselves. In these tests Amsoil's products are put through the ultimate rigors and unbelievably harsh conditions and STILL protect against breakdown and wear. The one thing about Amsoil is you won't see expensive ads on TV about what the company's oil "can or will do" for your engine like the "Big brands",however, with Amsoil you can read for yourself from unbiased third-party test results that PROVE Amsoil's greatness over competitor brands. As you can tell I am absolutely sold on Amsoil now days and run it in all of my vehicles even my lawnmower and snowblower. With harsh MN winters I need the best oil to protect with cold start ups. I would encourage everyone individual who is new to Amsoil, or even a long time user, to take a look at some of the testing that has been done on their products. Read the results! If you're still not sold on Amsoil I'm not sure what else to tell you.

Long oil life, keeps me going longer without having to do oil changes, engine sounds " heathy " less valve noice.

Amsoil is great use it in everything I own.

I always do all fluid changes in our Jeeps, changed everything over to amsoil and have never encountered any problems.

I've been using Amsoil in my vehicles for over 10 years now and in my opinion it is the best and less expensive in the long run. Less oil changes, less maintenance and better gas mileage. Over 280,000 miles on my 2004 truck and does not use a drop of oil between changes. Would like to see more in and out oil change businesses carry Amsoil.

Love all the Amsoil products. They've kept my 10-20 yr old engines clean and functional in severe heat.

Been using AMSOIL products now for approx 15 years. I use it in all my vehicles. I use change my oil every 10,000 miles with Amsoil filter. Never had an issue with Amsoil. Highly recommended,

When you buy something you expect it to do the job it was made for. AMSOIL does that for me. I became an Amsoil fan around 2001 when my Chevy pickup was first sold to a farmer here in Pittsburg. I was living in Alabama at the time and I had put AMSOIL in both my vehicles and was very pleased with the performance improvements i.e. mileage, performance, etc. We moved to Texas and my wife said I needed a pickup. Every Texan man needs a pickup, so we bought a 2001Chevy Silverado with 99,000 miles on it. It ran like a new truck. I immediately put AMSOIL in it and now with 132,000 miles on it it still runs like a new truck. I haven't had to do any maintenance on it other than maintaining fluids, tires, wiper blades and the like. And i expect it to continue performing like that as long as I have the vehicle. I will never use any product other than AMSOIL lubricants in my vehicles. I also use them in my Toro Zero turn riding mower.

This stuff is well worth it. Noticed the first oil change that my truck runs smoother and quieter(Toyota tick). Waiting to see the oil analysis when it's time.

I have been useing amsoil for over 25 years I have zero problems with it I run it in every thing I have

I have been running amsoil For over a year now. Naturally aspirated v6 in a 2011 Ford Explorer and TwinTurbo V6 ford F150. We know how turbo charged engines can generate heat and breakdown oils much quicker I really like the extended drain intervals and even with almost 13,000 miles on my F150 the oil that came out was still very thick. probably could've gone several thousand miles more. Usually with that kind of mileage and that kind of abuse oil comes out the consistency of water. I'm not easy on my vehicles either And tow from time to time. I just purchased oil, transmission oil, and filter for my Honda TRX 450 Atv. You have a customer for life!!
