Signature series has always held the highest protection standards for engine oil. Never an oil problem, and knowing that you are protecting the powerplant for your vehicle is so important nowadays.

I HAVE BEEN USING AMSOIL FOR OVER 20 YEARS ON ALL BOTH OF MY VEHICLES. I HAVE ALWAYS USED THE EXTENDED OIL FILTER SINCEL IT HAS BEEN AVAILABLE. I USE THE SAME OIL CHANGE PEOPLE EACH YEAR. THEY ARE ALWAYS SURPRISED THAT THE OIL IS NOT GRITTY OR THAT IT DID NOT BREAKDOWN . I WILL BE A LIFETIME PREFERRED CUSTOMER OF AMSOIL FOR LIFE.

Whether it's my daily commuter or my weekend toy, I use AMSOIL to protect my vehicle's moving parts and keep it on the road.

Good stuff

O put this oil 5w20 in a 2010 Ford Expedition,in march and it still looks clean great oil pressure,this is August??

I have been using this product from the beginning with my truck. I believe as a result I have not had any major engine trouble or turbo issues even after putting many miles on now

Love this oil. Been using it since the truck was new at 20 miles. Now have 233,000 on it and absolutely no problems with the engine. Oil changes have varied between 10,000 and 18,000 miles. :)

We use this oil in our Ford Fusion. We only put the best of oils in our vehicles and Amsoil makes an amazing product.

I've been an Amsoil Preferred Customer for many years. Have used most all of the Amsoil lubricants and other products at one time or another. Have never been disappointed. Love the way Amsoil continuously improves its products, including this Amsoil Signature motor oil. Try it. You'll be pleased, too!

I have used Amsoil products on both my motorcycle (2012 Victory Cross Country Tour) and car (2007 Dodge Magnum SXT) for many years, after the initial NEW break-in of their engines. This is an excellent product that I would recommend all to use.

Use Amsoil in all of our vehicles including the tractor! We have a 08 Cobslt with 265k Mike son it and still runs like a top!

I've had great results with Amsoil both on track and on the street. Love them.
