Best oil on the market.

It goes in my 3.6VVT and my 5.4 2V and does wonders for engine noise, oil change intervals, and most of all performance! It doesn't matter if it's a modern engine or not so modern engine, it Works!

Run it in all my vehicles. Not only engine oil but the best transmission and gear oil ever made available for the consumer! Independent tests dont lie...if you become a preferred member for $16 a year, all their products are cheaper than mobile one and pennzoil.

I have used AmsOil exclusively for over 20 years. It's the best there is. My truck loves it.

It's the best hands down! Some people think it's all the same ! There wrong! 25,000 miles you can not bet it.

This is the best oil I have ever used in my Ram 1500.

I use in my 1999 Corvette because I like to use the best, and also in my 2016 Dodge pickup.

First thing I noticed right away was how it make an already smooth engine even smoother and quieter. I've always used Mobil 1 advanced 15k oil and have heard nothing but great things about Amsoil. A co worker of mine had a teacher in tech school who used to rebuild his engine every year after racing season. He switched to Amsoil and hasn't had to rebuild it in 5 years. As soon as I heard that I was sold. If you want the best Amsoil is it.

I use this every 5k miles. The car runs smoother and quiter than my previous oil changes. It doesn't lose it's slickness. I'm overall satisfied with this oil.

I love this brand of oil and been using it for the past yr on mustang.

I have been using this product since vehicle was new and have had no issues with my vehicle. Engine runs great and strong and I change about every 15K vice 25K as put a lot of miles on this vehicle.

I have used this oil on my cars, trucks, and sedans. Never balk at the cost, knowing darn well I'm getting what I pay for. Less oil changes, frees up time, less waste, and superior protection.

Last truck had 175K and never used a drop of oil. Change oil, run 15-20K and still full.

After breaking in our two new 2017 Mustang GTs, performed oil/filter changes on both. The two things I noticed was quieter engine operations and a small increase in oil pressure. The engines also ran smoother than before. Overall, I'm very satisfied with the notable differences I've experienced.

I have been using this oil in my 02 siverado and 02 suburban since 04. 297k on the truck and 317k on the sub. Oil is changed once per year, have had 32k in one year on the truck. Engines still run great and have no oil consumption, increased fuel mileage seen on both. I don't use anything else

I used this on my 2002 Tahoe the oil at 3000 miles looks like new yet. In the very cold weather here in ND it start right up. Vary pleased with oil. I will be doing all the fluids in my Tahoe with Amsoil.

Unless I can't afford it Amsoil will be the only oil I use. It is very good and while some people say it is more expensive, they are usually comparing it to cheap oil, it is worth every penny. Considering the extended service length it is great.

Been using this oil for several years now and get great results from it
