Customer Ratings & Reviews

For years, I used mobil1. When the time came, I switched to Mobil 1 high mileage. About 2 years ago I started to get a subtle knock coming from the bottom end of the motor. It also started to use oil between oil changes. When I switched to Amsoil, not only did the knock go away immediately, my now 170,000 mile engine consumes no oil between oil changes.

The best oil money can buy

I've been using this for some time and never had any issues what so ever.

use it in my truck so far so good

I use this and many other amsoil products for all of my vehicles since 1972 and have never had any kind of a pproblem. It's simply the best.

Great product and price !!

I find that the XL works great, and is not as expensive as the Signature Series. I change the oil every 6 months or 5-7000k miles regardless, so I see the XL as excellent for those of us who do regular fluid maintenance.

I have been using this oil in my present 2012 Honda Pilot since I bought it and is excellent oil. I also used it in my 2000 Acura TL for about 4 years before I sold it. Never an issue with oil problems using this oil..

I have used the product in multiple cars that I have for 3 years with no problems to speak of

great product does what it says it does

I've just started using this, about 3,000 miles on my 05 Prius and the oil still looks clean. Gas mileage stayed the same.

Great oil

Use in my 96 Avalon and 2001 Lincoln LS. Love it!

Great stuff. Wouldn't use anything else.

So far so good!

My mechanic brother in law got me hooked on amsoil products from oil to additives... and I'm glad you can tell the difference in just the sound of the engine and the performance no matter what you use ... I'm a believer in amsoil product now.

Purchased the product for my 2015 Subaru. I have used Amsoil products in all my vehicles, including motorcycles, for many years. Have never had a problem that was oil related. I am very pleased with Amsoil products.

I used this in my daughters 05 Kia Sportage. She is six hours away at college and I can't be there to monitor mileage intervals. With the XL and the assurance that she can go 10k miles between oil changes. I can take care of the maintenance on summer breaks.

I love the fact I don't have to change my oil 4times a year mow that I use the fuel saving XL 5 W-20.

I've been using Amsoil XL motor oils and EA filters now for over 10 years in all my vehicles and small engines such as lawn tractor, snowblower, etc. The lawn tractor is a John Deere and is 32 years old. Engine still runs strong. All engines appear to be wearing just fine and the internals remain extremely clean. I change oil and filters in my on-road vehicles every 6000 to 7500 miles. Great products, and I will continue to use the XL motor oils because of their excellent price/performance value.
