Customer Ratings & Reviews

I’ve been using Enzo for about four years. I first used it in a jeep, an old Jeep and it’s the best thing ever done.

All I have used in my 2015 Grand Cherokee since she was a yr old and 10k (had a free dealer change at 5k) and just had the oil changed today. It has been this weight Amsoil over and over - 90k and 9 changes with this oil and it generally looks very normal or barely used when taken out after 10k miles. This is the first time I have tried the high mileage version, so we'll see if it is as good as the std 5w-20. I feel pretty certain it will be!

Great oil in my 5.7 hemi. Engine runs smooth and quiet. Better fuel economy consistently.

I was thrilled to discover that I can order Amsoil and associated products directly from the manufacturer. I used Amsoil for years until I moved to an area that didn't have it any local stores. My only complaint is that I didn't get an Amsoil decal in my order.

Using Amsoil for more than 10 years, no issues. Only one engine lost but don’t know engines history before I got it. It was not oil problem. I will continue to use Amsoil.

Best oil out there, 35 year old Jeep and still going strong.

Everything was Awesome

Great product hands down ! I use amsoil in all my vehicles and atvs !

Best oil for high mileage Jeep Wrangler 3.6L.

Highly recommended!

My son in law got me started on this oil and it is now the only one I use. My car runs alot better with it

Very good product car runs smoother and gives me more confidence that my engine is properly protected from viscosity breakdown

This oil exceeds Royal Purple, a brand I used until now.

I have been using Amsoil oils and filters for quite a while and I couldn't be more satisfied with them. I would recommend them to DIY car owners.

I have a 2018 Subaru Impreza. I was starting to get bad gas mileage around 145,000 miles. I switched over from using OEM oil and filter to using a wix xp filter with this oil and my gas mileage went back up significantly. Also, my engine sounds like it is idling more fluently and quietly again. I can’t say enough good about this product, I will be a life long AMSOIL customer.

Never had an oil that made the car feel different after you changed it. Awesome.

Awesome. Never had an oil the made a difference to the car that you can actually feel.

Great oil with an awesome name. Aside from the filter, you send everything i need to do the task. Top all that off with a guaranteed mileage or timeframe. Bravo

Best oil I've ever used.

Excellent oil.
