Great

Love the oil. Well recommend to use it

I have used Amsoil for many years! You get what you pay for. You spend thousands of dollars on a vehicle. Why not use the best lubricants on the market?

Love this stuff engine purrrrs.

I have been using this grade of oil for the last 17 years. It has been performing extremely well. I change the oil filter every 12,000 miles and the oil is changed every 24,000 miles. Between three vehicles, we have logged over 500,000 miles on this oil. It is a keeper.

I have been using this product for over 10 years. I get 25,000 miles an oil change. Most of the time a year is up before I have made it to 25,000. Never had a single problem. Started using it in a 2003 Ford Excursion that was burning a quart every fill up, has not used any oil for 5 years now. Try it you won't go back to your former oil.

This is the oil my entire family uses. I have it in my 270k+ Corolla and my 1.8L engine is still rev happy and snappy. I drive 100+ miles a day, and I can tell you from experience, there is no other oil that could stand up to this kind of punishment.

I have to 2019 Silverado and the amsoil cleared up the hard shifts and the torque converter shudder. It is now better than new. After having the motor replaced I was very worried about my transmission, I gave it a try and its nothing less than awesome. Thx.

Best oil you can use. I have my oil tested every time I change it. Always tests great and I run it hard.

I have been using Amsoil for years now, best oil on the market.

I’ve been using this oil since my Mazda CX-5 was brand new in 2024, changing it every 5,000–5,500 miles. Occasionally, to keep the interval even — for example, if I’m at 16,500 miles and it’s time for an oil change — I fully replace the oil and filter with Castrol Edge Extended Performance until I reach 20,000 miles, and then I switch back to Amsoil SS. During those few miles with other oils like Castrol or Pennzoil, the car starts making all sorts of noises from the engine bay, behaves strangely, and drives noticeably rougher, almost like something isn’t quite right. Some might think I’m exaggerating, but I drive my car more than 10 hours a day nonstop, and I know every detail and sound it makes. Once I switch back to Amsoil, the car feels brand new again — all the weird behavior goes away. Since then, I’ve been using Amsoil in my motorcycle and in my generators as well. My family recently bought new cars (0 miles), and we’ve already purchased their SS oils to protect them from day one.

You can see how well this oil cleans even when you pull the dipstick and how it cleans the oil right off of the dipstick. This is a great product.

I have used this oil in my 2022 RAM 2500 truck since it was new with no issues I now have 66,000 miles on it so the truck is driven daily. I would not use any other oil.

Super smooth, keeps my engine running smooth

I purchased the 0W-20 Signature Series and an Amsoil filter for our Toyota Sequoia, with the 5.7 V8. As most of the Toyota owners know, Toyotas are typically loud. After changing the oil, there is a noticeable difference in the noise from the engine. I've used Royal Purple HMX in our 2007 Toyota Highlander which has held up great, making noticeable changes to engine noise and cleaning the engine. I'm hoping Amsoil will do the same, but time will tell.

Looks good so far. Amsoil had the oil in the 0-W16 I needed. Received it in very short time after the order. The long game of mileage will tell more how the oil does. How many miles on the motor since new before any major issues in the engine. Time will tell.

Best oil ever

Only the best Synthetic Oil, Oil Filter for Dodge Durango

I use Amsoil oil and filters ( i wish they had a wider selection for the small engine oil) i find Amsoil products superior over the competitors products.

AmSoil is a quality oil and the fact that they ship it to my front door with in 2 days of ordering online is a bonus. They also offer an oil analysis which I use to monitor my supercharged mustangs engine running E85.
