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.

My truck (Dodge 03 1500) has 140000 on it. Amsoil has been there for me the whole time. Not one single issue. Runs like a champ. I run Amsoil in all my vehicles including my Harleys after initial break in period. I live in Tucson Arizona & Amsoil holds up great against the heat. Keeps everything running cooler. Oil is not all the same as many say it is. Big difference.

I use the XL series for my personal vehicles. 2006 Mazda and a 2008 Chevy. I am very happy that my vehicles run and operate like brand new everytime.

Awesome oil. Love it

I bought my 1992 Toyota with over 150,000 miles expecting to replace the engine soon. I have used only Amsoil long life oil since then. I do stop and go driving all day. So far no engine work and it just keeps running. 520,000 still drive every day.

This summer I decided to do my #1 bucket list trip of a lifetime and I drove cross-country from Connecticut to Oregon/Washington and everywhere in between. I used amsoil for the first time in my 2013 GMC Terrain (new to me in Feb.) and I drove over 8,000 miles in 3 1/2 weeks. I never had to add any oil and my vehicle ran perfect. I was over 10,900' elevations and others many times on the drive out and back and was in temperatures from 50-95 degrees. I am now hooked on using amsoil in my vehicles and thank my boss for recommending it.

This stuff is fantasticit last and last it stays clear to light brown for an easy 10,000 miles

Been using Amzoil for over 15 years.

I used Signature Series 0W-30 for 70,000 highway miles in my motorhome. When I bought my 2016 Subaru Outback, ( which calls for synthetic 0W-20), I wanted to use Amsoil in it. I have 2 free service but I buy Amsoil 0W-20 and the appropriate filter and give it to the service dept to put in my car. I think Subaru's synthetic oil is made in Canada. I trust Amsoil and not some oil I've never heard of and don't know anything about.

Outstanding product I change oil at 10,000 miles not the 3,000 dealer oil change (so they can get in your wallet more often). I have 200,000 miles on my truck and 130,000 on my Toyota Hylander and they use about 3/4 qt of synthetic oil between oil changes. I use the highest rated Amsoil oil and air filters with every oil change.

It makes my camaro run better and gets better fuel mileage.

Used in my daily commuter. 120miles a day. So longer oil change intervals is a must. 10k miles every change. I had 2 oil analysis's done both came back showing minimal wear if at all.

Try Amsoil once and your car will run smoother.

this is the best there is as a former aviator using synthetics in turbine engines worked great so if its great for aircraft engines then its equally as great fro your vehicle
