Amsoil is a quality oil. I use Amsoil in all my vehicles.

Obviously, I'm a bit disappointed that there is a filter shortage these days. Since we are only changing once per year, hopefully production will be in place for the next go around. Remember, AMS means aerospace material specification!!!

I switched to the signature series, now that I am getting my vehicle tuned, and going to be demanding alot more from it. Hope it treats my motor just as good, and the regular version of Amsoil I was using before the tune.

Have used Amsoil since 2009 for all vehicle fluid and could not be happier. 100% synthetic has yet to disappoint. Even if I forget to change an go a few thousand miles over a normal change.

Excellent motor oil …

Oil sample sent to Blackstone Laboratories to test for oil viscosity and engine wear. Part of the report said, "In short, your engine is wearing exceptionally well..." I'm very pleased and Will continue to use and recommend this product

Fast shipping. Acura MDX. Peace of mind on blistering hot days.

I’ve been using this oil for my gas cars now for several years and it works really well with high mileage cars and SUVs. I noticed smother idles and lower temps with Amsoil products.

Highly recommended oil. I run this in my 2018 Nissan Titan and my 2013 Victory Cross Country tour. No issues Any future oil changes will be Amsoil .

I started using AMSOIL when the original name was Amzoil (after Albert Amatuzio)). Synthetics were a bit of a novelty back then. Since then, I’ve had vehicles that I’ve sold with over 300,000 miles on the odometer. They all used very little oil, eventually, and maintained above average fuel economy. The best of the best and well worth paying a bit more for. The long term cost has been significantly lower. AMSOIL passes the test of time.

You didn't have the oil filter I needed, again. Had to buy from a local parts store.

Superb technology and piece of mind when using this product.

I have been using this oil for years in my truck, cars, and motorcycles

Feels smoother and last longer. All I get for me and my wife’s vehicle

I love the product. And great delivery service. However, was unable to purchase AMSOIL filter due to being out of stock. Had to buy the WIX.

This oil is superior to all other brands ! Amazing product with great results

In my opinion, this is the best oil you can buy for your vehicle. I've been doing my oil and filter changes myself for the past 50 years and I've tried them all. You really can't beat Amsoil full synthetic oil. They're filters are excellent as well.

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.
