Great product

Using this during the winter in my WRX, switching to the AMSOil 5w-30 in the summer. No worries using this 0w-20 as it's better than every other companies.

This is about as good as it gets for longevity and mileage. 25K intervals for changing oil is unprecedented and will be experimenting on my truck.

So far I've noticed better mpg in both vehicles will send off to test oil sample I. Fee months and will compare my results with royal purple results but I am sure this is the superior oil of the 2.

I love these products. Normally, I would use the AMSOIL XL, but I switched to this a couple of weeks ago and noticed the engine ran quieter and smoother. Thank you!

Good

Excellent product that works well with my wife's 2010 Hyundai Elantra GLS. The engine doesn't miss a beat and is ultra quiet with the high lubrication properties of this oil.

I've using this in my '06 Dodge Stratus since new. I've just rolled over 70,000 and put the bore scope down through the oil fill to see how the valve train looked. It was remarkable. It didn't even looked like it had been run. Everything looks new. No varnish at all. These 2.7 V-6 Dodge engines don't have the best reputation either. Known for sludge. Running good as new with 10W30 Signature Series.

I have a lot of good things from friends so I ordered a kit for my 2015 Nissan Xterra and I’m impressed. 1- Sounds much smoother on a cold start especially. 2- Has increased my mileage a little bit. 3- Highway speeds motor sounds great, I did put a cold air intake and cat back exhaust on it but I can tell a difference since the change. 4- Delivery was pretty fast, 2 days I think maybe 3 but nice. I plan on ordering rear differential lube and front.

Only just started using this one and due to the great success I have had with using Amsoil products, I am expecting extended years with the new vehicles and oils. I am using this in two different high reving turbo charged engines so a bit different for me. But I rely highly on the product Amsoil delivers.

I have been using this oil on a 2013 Honda Accord for greater than 220 thousand miles and believe it's a big reason the engine is working awesome. I average one to two oil changes a year and the car still gets 530 to 570 miles on a tank depending how I drive. I use Amsoil in all my vehicles and highly recommend it.

Since I have started using your oils my Vehicles seem to be doing better with oil consumption gas milage I use your products first They work!

I switched to Amsoil 8 years ago and will not use any other products. Far superior than all others. Very fast shipping as well.

Made my 2015 Jeep Wrangler run better than Mobile One, Amsoil is a great product

The AMS website could be a bit easier to navigate for those just seeking to replicate their most previous orders. There should be a quick link in "order history" to reorder the same items again without having to navigate through the website to find one's oil and put into the shopping cart. Make this easier to repurchase!

This is the only lubricant I fully trust for my vehicles

Simply the best synthetic oil on the market. Ordered via Amsoils vehicle configurator and received the oil and filter together and ready to use. Happy customer and happy pickup!

Great product great service

Been using Amsoil for 4 years not disappointed

Hello, I recently switched my Ram 1500 over to Amsoil Signature Series 5W-20 motor oil. I feel this product is superior in every way, it has superior heat resistance, there is no loss of viscosity after multiple hot / cold cycles and overall I think it's a top of the line product. My last truck was a 2017 Toyota Tundra with 95,000 miles on it. After running Amsoil, the engine sounded like a road off the showroom. I will continue to use this product for any engine.
