Best oil on the market

Before i used amsoil my engine had a loud and very noticeable tick. After switching to Amsoil synthetic the tick went away and the SUV sounds like a new car. When stopped you can barely hear the large 5.9L V8 idling away, it so quiet.

If I go past my oil change I don't have any concerns because the oil still looks new and protects my engine.

This is a great product and works well in any vehicle.

I use it in my f150 and I love it

I used it in my motorcycle and it quieted the engine right down and it ran smoother than ever.

changed from 10/30, works like a champ in my 2005 Silverado 225,000 miles pressure stays constant even under load

In all types of trucks, cars, boats and motorcycles

My truck mileage increased as soon as I switched from Mobil 1, truck has 260000 miles on it

Put this in my light duty, full size pickup. Noticeable difference right away. Engine quieter and clean.

I've been using Amsoil products for over 30 years. I had stopped for a period of time. I've been using this product now in my 2015 Focus since I got it. 30,000 miles and the inside parts of the engine I can see through the fill port are as bright and shiny as the day I bought it.

I have been using Amsoil for years. Everything from Signature Series to XL. All of my vehicles out-last anyone else's I know. I gave my daughter a 1997 Toyota Corolla years back and just put it to sleep with 387,000 miles on the clock. I have a 2005 Acura RL with 168,000 miles and it too runs like a top! I attribute the use of Amsoils synthetics to its longevity and have no doubt there's another 168, 000 left in her. My 2004 Dodge Ram has been on a once per year oil change interval since I bought it. It too will easily give me another 100,000 of service! 2012 Prius V. with 105, 000 miles and the oil still looks clean after 10,000 mile change intervals.

Car runs good with this oil and better fuel m8leage

Great product, use in my pickup, have used for 12 years, in 2 trucks. Retired Wisconsin snowplow driver, and switched to Amsoil, because my pickup would be outside at work, for up to 16 hours, in below zero temps. No problem turning over and starting, after switching to Amsoil.

I use Amsoil in everything I own that takes oil. Lawnmower, cars, diesel truck, tractor, motorcycle.

The Amsoil XL series has protected my vehicles for many years. When the formula was changed to protect against Low Speed Pre Ignition (LSPI) as well as an extended drain interval, I knew it continued to be the right lubricant for the job. Recently I purchased a pickup truck that could be vulnerable to LSPI so this formula change was very timely. I appreciate that Amsoil offers many choices for lubricant applications. This is a better approach than "one oil fits all" approach.

I began using Amsoil products in 1996 in a Buell S2T, with a HD Sportster 1200 engine. The temperature change from HD oil to Amsoil was almost 20 degrees cooler. I have never had a mechanical problem, including no clutch slipping with the bikes. I use it in my 2006 Victory 8 Ball, our 2010 Lincoln MKX, and my 2000, 2004, and 2013 Ram Hemi..

Have always used either Amsoil or Mobil 1. Both are great oils and and every other oil change at 7500 miles in my Toyota Tundra, Lexus, Mazda and Honda CRV. I send the old oil off to Blackstone for analysis. The analysis of Amsoil and Mobil 1 both always show excellent wear and Blackstone recommends that I could go much longer between changes. Thus I usually buy Mobil 1 because I can get it at Costco, don't have to pay shipping and this makes it much cheaper.

Have used synthetics in all my vehicles for quite a few years now. You can tell the difference the first time you change over to synthetics.

I use this in my Chevrolet Silverado and Kia Optima Hybrid and follow the manufacture recommend oil change interval.
