Customer Ratings & Reviews

I use this 0w-20 in all three of my vehicles. Oil samples always come back looking great. Easy to order and arrives quickly.

This product is great, and all of the AMSOIL products are great. The oil filters they can’t seem to keep them in stock.

Improved engine noise.

I’ve always used azole and it’s never let me down. I love it.

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

Who the hell ever heard of 0W-40!!?? Anyway, I use this product in my camper tow vehicle. We travel through the mountains, many miles. Lotsa sustained high rpm’s. Truck never misses a beat, oil holds up, no BS! I’ll pay the premium to have this level of protection to keep running this truck in the manner it was designed for!

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 have a Honda CR-V and after the change the car ran much smoother and the cold engine light goes out almost immediately after starting the engine! I know Amsoil is good all around for an high-end synthetic. It remains to be seen when I have to have the oil changed.

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.
