I’ve used all types of oil but amsoil just seems to be right for my conditions as it just looks cleaner on drain intervals vs others at same intervals. So I’ll keep using till that day if it ever comes that it can prove that it doesn’t surpass the others I’ve used.

A soil is always great, ordered oil on website and it was delivered 3 days later. Arrived in good condition and exactly what I ordered.

Very good oil fast delivery

I have been using this product after my first 5000 mile oil change. The 2010 Toyota Tundra Rockwarrior now has 260,000 miles. Excellent Motor Oil.

This is excellent oil for my 4Runner. Shipping is very fast and Amsoil makes the order process very convenient. The bottles are shaped perfectly to pour without issues and are sturdy enough to contain the used oil for recycling drop off.

I have 2 motorcycles and 3 vehicles and I only use Amsoil in all of them. My Trailblazer has Amsoil from front to rear where ever it would go. It's a 2006 and had less than 40K miles when I bought it 2 years ago--Everything else was new and only has Amsoil used in them. Only thing I will use and recommend when you want the best for your ride!

Excellent product Would highly recommend I believe it will extend the life of the engine

It should be a 5 qt bottle not 4 qt. Shrinkflation sucks.

A little cheaper price but still great protection, paired with an A soil oil filter!

Some of the best oil I've ever used and will recommend it to everyone! You will instantly feel a difference in your engine idle and the smoothness through the RPM's. Being used in a 2002 Subaru Impreza WRX

All Amsoil products I've used have been excellence. This was for my fiancée's car, an 08 Toyota Camry with the 2.2L engine, with about 310,000+ miles on it, and also the Toyota engine that is notorious for oil consumption. Has helped a little so far, usually takes a 2nd oil change before there's a noticeable difference. Had the same problem in a 05 F150 with about 280,000+ miles on it. Was having to add about a quart every other week, started using Amsoil, in about 6 weeks, no more oil loss.

I have used this oil since 2005 when I started using AMSOIL products. I use it in my truck and my wife's car. I change my oil once a year and it really looks good when I change it . I probably could increase the time between changes but I follow the AMSOIL instructions about doing it once a year.

I use amsoil in all my cars

My 2020 CRV runs so well on this oil. Fuel mileage has improved by 1mpg to 32.9 in town. I have my local Honda dealer use this during service. They charge a little bit extra, but it is well worth it.

Amazing product will be using signature series the next time! I’m hooked

I love the Amsoil boosted. It’s a little cheaper than Signature Series and it has a robust additive package. My engine runs very smooth!

I started using the XL 5W-20 when my daughter bought a used 2009 Kia Sedona which calls for 5W-20. I did an initial Amsoil Flush which produced some evidence of carbon deposits in the filter pleats. I've continued with XL over a number of oil changes. The Amsoil synthetic continues to breakdown carbon deposits, so the cleaning effort continues. By comparison, my own cars, which have been on Amsoil for years, show filter pleats that are significantly cleaner at oil changes - basically just a brownish color change instead pleats with accumulation. It continues to improve!

The products I have used from AMSOIL have been amazingly great for my vehicle. Recommend using any of their products.

Ordered this from Jacob Rodriguez. He assisted us through the entire process of choosing our oil and was very helpful. Will be a reparations customer.

Now I am using this oil. but my car is so old still getting problem.
