Tried Amsoil for the first time, and I will never go back to any other brand.

Switched to Amsoil after watching Project Farms oil contest YouTube video. I run it in my Grand Marquis and Hyundai sonata both run like new.

158,000 miles on Ford 250. Run much smoother than Mobile1 that I have been using. Changed my oil 2 weeks ago, took a trip to Florida last week and ran great for 3000 miles

This oil is the only thing that my engine's see for Essential Lubricant for great protection

I do oil changes myself and this last oil change was different. I used amsoil and I felt my car run a little better and made a lot more pops than usual. If you are wanting to make your car run nice I recommend this brand. I am only going to use this oil from now on. Thank you!!

My truck have only 1000 miles so I don't feel any difference, but engine sound quieter.

Ran royal purple one time in my 2019 tacoma and I noticed the engine was louder than normal. After checking the oil and keeping an eye on it I decided to drain it and put in amsoil. After the first few miles I could tell it helped quite the engine back down to how it used to be.

The Amsoil 0w-40 synthetic is the best oil for my Challenger Hellcat SRT engine. My engine burns less oil than with Penzoil that Dodge recommends. With Penzoil, I’m adding a quart between oil changes. No added oil with Amsoil. Dodge should switch to Amsoil like I did!

Used AMSOIL products for over 15 years in cars,trucks,heavy equipment,and 2 cycle equipment.Would not use anything else. Always had excellent service,and good customer support.

Have not used yet, but you can't beat Amsoil.

Just changed oil the other day on 2013 suburban. Seems to have better oil pressure now better then after doing the previous oil oil change let’s hope it helps.

I can feel the difference between this synthetic oil and the previous brand which is a very good brand too. The acceleration response is very noticeable.

Based on testing, Probably the best oil available.

Use this in my 2017 Hyundai 2.0 Turbo and only change the oil after 1 year or 15K miles. Been using it since car was new. So far no issues with motor or using any oil. Motor runs like new.

Love it not as many oil changes and better protection

I used this oil in my 2013 GT500 since new. In that time I have never had to add any oil within the oil change interval (4000km a year/ once a year oil changes). I borescoped the cylinders every now and then and could still see the cross hatch on the cylinders. I now use it in my 2021 Roush Supercharged Mustang GT.

My vehicle went from 29MPG to 32MPG. My Toyota Matrix feels smooth when i step on the gas.

I've used the AMSOIL Signature Series motor oil for several years now and think it is an excellent oil. I just wish it was more available near where I live. I have found it at Rural King near me but they do not carry it in the weight I need for my vehicle which is 0W-20. But when ordering it online it has always arrived in 3 or 4 days.

I was skeptical at first about amsoil then I researched and read all the great things about there oil and I am so happy I gave amsoil a shot. My mustang is running so much better than when I first bought it and I gained 2 to 3 mpg. I was so impressed by the motor oil and now my transmission and differential now has amsoil running though it.

Amsoil is the only oil used in all our vehicles. It keeps the engine clean even past if for some reason the 1 year or 25,000 miles. My son had his 2012 Nissan Maxima in Nissan shop for work and the Mechanic told him after 25 years working he had never seen an engine as clean as his and it was due the Amsoil oil he uses.
