I would recommend this oil to everyone that I know.

Best oil for our Camry that has performed so well Best extended drain intervals- Keeps engine clean and running smoothly

Helped with an oil consumption issue on a 03 Silverado 5.3. Definitely the best synthetic on the market. Thanks, Amsoil!

Long lasting good quality oil. A bit pricey but you get what you pay for

I have Amsoil for 5 years in all of my vehicles. Engine runs smooth and quiet. None of my vehicles have needed oil added between oil changes. Good Product

Been using Amsoil many years.

I stopped using amsoil and switched back to mobil1. I noticed the oil got darker much sooner than when I was using amsoil. So I went back to amsoil.. Since my intervals are longer with amsoil the costs are real close to the same. This is the good stuff. running it in my ford edge 2015 3.6L

Great stuff for the wife’s Toyota every 12000.

Been using Amsoil for 20 years and not about to change. Their products have proven themselves superior over everything else every time I’ve needed something different. I have Amsoil in so!

Have used Amsoil products since the late seventies. Finally decided to switch my last vehicle (2006 Jeep Liberty that I purchased new and had 152000 miles) over to Amsoil XL for easier double digit below zero temperature starts. It turns over much easier with the XL and added bonuses are the main crank seals stopped leaking due to the seal conditioner in the XL oil as well as the number 2 cylinder spark plug stopped getting oil fouled. Great product and I now have zero petroleum based oil on my property.

I’ve been using this for years and am completely satisfied, great product and fast shipping.

I’ve been an Amsoil customer for 20 years and never had a bad experience with their products. Customer for life.

I’ve been using Amdoil 10/40 since 100,000 miles on my Impala and stopped using 1 qt every 3,000 miles. I change my oil every 6,000 miles and only down 1/2 qt. It’s worth the extra money.

Good quality & less expensive than Signature Series.

When will Amsoil Extended Life be available in 0W-16 weight? I love this oil but can't get the fuel I get with 0W16 oil

You can't beat the product. Yes it's pricey, but you get what you pay for.

The oil and other products you have are top notch, but my one beef is the freebies you send out now and then with orders, paper oil funnels, really and when I try to use a code on something I'd like it says my purchase doesn't qualify, how about free shipping with my membership that's all I ask, otherwise great company great service superb shipping time

We keep in stock and use on classic vehicles.

I've been using this oil for years and I have never had a complaint. I put a lot of miles on, and being able to extend my change intervals is a huge benefit.
