Customer Ratings & Reviews

Have used HM520 in my hi-mileage 2012, 3.7L Ford for several yrs. Engine internals are very clean. Strong product!

Great oil and lubrication products

I trust this all day

Can’t say enough about Amsoil. We don’t run the oil as long as we could just because I like to have a buffer for times when I can’t get time to change the oil. Oil runs cleaner longer and has plenty of protection left when drained

I have been using amsoil for over 10 years. I won't be changing and I'm going to keep using this brand on all my vehicles

I have been using amsoil for more then 10 years. And I will keep using it on all my vehicles

I only use AMSOIL in my vehicles, lawn equipment and generators. The latest purchase was for my 2019 Ram 1500. I have over 145K miles and haven't had any issues with the engine.

Amsoil is a great supplier of premium products and service. I've used their lubricants and filters for years with impressive performance and longevity.

I will only ever use amsoil

🐐

The quart bottles are perfect for pouring and also large enough opening for a descent size funnel to pour my used oil in.

Been running this product for years with zero issues in customer vehicles and personnal. No abnormal wear on components and engine valve trains run quietly.

We have used this oil for 28 years in our fleet

Great oil. But the prices are going to have me a decision on staying with them or going cheaper. Just under 700,000 miles on my vehicles using this oil with no problems Price is my only complaint

Excelente

I own a 2012 chevy Tahoe, it got 390 000Km on the odometer, I always ran good quality synthetic oil in it but the engine would always have a ticking sound coming from it. Since I switched to Amsoil high mileage the ticking went away and the engine feels more responsive, I will continue using Amsoil until the engine dies, I just regret not switching to this oil earlier.

This is my second time using AMSOIL. I’m not sure if it is the right one for my car . After changing the oil, the car makes a loud noise. I’m used to liking Pennzoil . So I am going to try AMSOIL for a few times. I’m hoping better . I like AMSOIL transmission fluid and gear oil.

I've been using this oil in my truck since the second oil change after I bought it. My truck is 17 years old now and still motoring along. This is good oil but then that's a known fact.

You notice a difference at startup that lasts throughout the life of this oil.
