BEST THERE IS, DON'T SETTLE FOR LESS !! VERY FAST SHIPPING..

I have used this oil in lots of vehicles for a long time. The multi viscosity feature of this oil doesn't break down. The 0 viscosity means the car will start all winter without plugging the car in. I change oil every 10,000 km and have never had engine problems.

Really good oil but the bottle os not easy to use/pour, it will be good idea if Amsoil create a friendly bottle to use.

I’ve been using Amsoil synthetics in all of my engines for over 20 years and highly recommend them. I also use their synthetic greases for all vehicles and equipment.

very good

This is simply the best oil in the world. No other way to put it. Its probably to good for a daily driver but it gives me the piece of mind.

Quick delivery of an awesome product, used for many years now trouble free

Great oil, Always starts outside in the winter, and the vehicle uses no oil between oil changes.

Been using amsoil in everything I have for years. Very happy with the results.

The first time I tried Amsoil the difference in performance and mileage was so noticeable I've continued using it in every vehicle.

Amsoil signature series is all I will use in my Mustang Mach 1. At the 5,000 mile mark the oil isn’t even dark and I’m not easy on that car. Granted it takes 10 quarts and it’s not cheap but well worth it to me.

Amsoil is simply the best oil out there. I tried another synthetic name brand that starts with an S and it doesn’t even come close. Amsoil hasn’t even started to oxidize when it’s drained. Every other oil is severely oxidized and breaking down when it’s time for an oil change.

150,000 miles with no problems, thanks to the Amsoil 0w20 Signature Series Oil. Cleanliness that is unmatched due to great additive engineering.

The best money can buy , ive been running amsoil since 1992 in everything I own /race I have a cpl v6 explorers with 300,000 miles and the inside the valve covers is just as clean as the it was new . I run it in my Harleys,jetskis hell even my weed eaters chainsaws and will continue to use it until I expire.

Came quick exactly as ordered thanks

I use Signature Series 0W-20 Synthetic Motor Oil on both 2015 Subarus. This allows me to only have to change the oil only once a year. I have doing this every year I owned the cars. Both cars run as good if not better then they were new. I have complete confidence in Amsoil for protecting my Subaru engines.

Great product. Fast delivery, had it in days. I have been using Amsoil in my Harley and now doing the same for my Explorer. So far, so good.

This oil is a quality synthetic oil at a great price.

It's synthetic oil. My Mazda likes it and if she is happy, I am happy.

No question on who creates the top oils.
