Customer Ratings & Reviews

Been using Signature 0w/20 in my MDX and girlfriends CRV. Oil samples at 15k intervals show very minimal wear metals and still outstanding viscosity . The CRV has the dilution issue and after the sample results it hardly affected the oil. 10k for the CRV from now on. Best oil to deal with dilution issues .

I've officially changed everything to amsoil!!coolant, oil, gear oil, radiator fluid, now only time will tell if it makes a difference!!

Truck runs quieter, engine even a little cooler running

Best oil on the market for my 2024 Ford Ranger Raptor direct injection twin turbo engine. For protection and wear this oil is my favorite.

Outstanding oil, which is worth the investment to maintain my motorcoach and generator. Very highly recommend!

Great product best oil !

Best oil I have ever used in my Cars. The oil holds up better and longer in the everyday use than any other. Love AMS OIL.

Great oil and always prompt delivery of products I buy on line. I can tell my truck runs smoother after switching to this oil.

I think Amsoil is the best lubricant for any vehicle. it does a great job in my Cadillac, also I use Amsoil in my diesel truck which out preforms all other oils.

awesome product, been using it for over 10 years. its the GOLD STANDARD in lubrication.

Have used in past Last truck I owned sold to friend has over 300,000 miles on same engine testament to oil treated parts that I used regularly for the first 120,000 miles

I don’t use anything but AMSOIL in my vehicles. Soon as they are broke in they get a fresh AMSOIL change and stay that way. Thank you for such an amazing product.

oil quality is excellent as expected. and honestly, the gallon jug is a fantastic size! much easier to handle than a 5 quart. I'll be ordering another 4 pack in the future!

I've been very pleased with AMSOIL Signature Series motor oil. It has performed exceptionally well in my vehicles, and I appreciate the confidence it gives me in long-term engine protection. I also use AMSOIL fuel treatment products and have experienced smoother operation and dependable performance. Based on my experience, AMSOIL has earned my trust and recommendation.

AMSOIL was recommended to me by my dealers Honda Certified Master Technician who services both our cars. He personally uses it and with all the reputational history I’m confident we’re using the best.

The filter wrench was awesome This is my first time using this product Everything arrived on time and in perfect condition

The oil holds up very well in my Escalade!

Timely delivery on quality product.

As good as oil can get. I’ll never see the difference vs regular oil, but makes me feel better having a superior product.

Started using Amsoil SS and Amsoil filters on my car about 2 years ago. The next oil change after switching to Amsoil, I know longer get any fine metal glitter on my drain plug magnet and haven't since. That's proof to me that it works! I now use Amsoil in everything I own that has an engine.
