Customer Ratings & Reviews

After we did this change (from Mobil1, so not from a regular oil, and she’s always used synthetic) in my daughters CR-V she noticed immediately smoother running as she did a few three hour road trips. I use it in all my vehicles, cars and motorcycles.

I switched my 2010 Jeep Rubicon to synthetic 5W-20 and it runs much smoother. Installed an Amsoil filter also. I will draw a sample and change the filter every 7500 miles and have it tested in a lab. Lab results will determine when I change the oil. I also changed the front and rear differentials to a synthetic Amsoil.

Amsoil is the absolute best oil for GDI Turbo motors. Science not opinion supports this. 2nd best oil may surprise you, It is Pennzoil Ultra platinum. But I will stay with AMSOIL for my LUXURY and Sport Cars. There is absolutely none better.Hey the invented synthetic

Great product

My Nissan Frontier 2010 is at 368000 km, and runs smooth like a sewing machine..started this oil about 2 years ago..also used amsoil oils in drivetrain...rear and front diff, transfer case, and transmission..definetely worth paying more! Should have used all these products from the get-go!

I run this in our 2017 Honda Pilot. The best on the market. On a downside still waiting on the EA15K13 oil filter

I love this oil formulation as well. I use this in my older Lexus, and it runs awesome after nearly 200,000 miles. Fantastic

I've been using AMSOIL for many years, and it's the best in my opinion. All of the formulations are top notch I will continue to use AMSOIL

I've been using Amsoil since the early 90s and it's never let me down.

No complaints on the product. However, the promo gift was never received

It’s amsoil what more to be said

Keeps all my vehicles lubricated and clean. Great synthetic lubricant

Great products, such an easy when ordering as it comes in a complete kit.

Why settle for anything less than the best!

I don't understand why my chevy v6 243 engine goes throught this oil, with no smoke out the tailpipe

In my opinion this is a much better oil than the manufacturers recommended Mobil oil. Getting better performance !!!!

Great stuff

Do your research. It's hands down the best motor oil.

Amsoil gives my high performance truck the protection it requires. When I’m hitting speeds of 120mph on the track!

I have been using the signature series since it came out without any problems on four different vehicles. -I stared using it in 2010 with my 2002 Mercury Sable. After running it for one year I had it tested, not with Amsoil, it came back perfect so I stated using it on my other vehicles. I sold it in 2014. -1999 Ford F150 now with 188,000 miles. I used AmsOil starting at 500 miles then switched to the signature series starting in 2011. -2008 Navigator 44,000 miles in 2014 now with 110,000. -2008 MDX 97,000 miles in 2017 now with 155,000 miles. All will be getting their yearly April AmsOil oil change. I do have to add about 1/2 - 1qt. of oil about 6-8 months after the oil change.
