Customer Ratings & Reviews

I use the signature series on both my cars and one is a 1999 volvo s80 and still running great.

Been using Amsoil Signature Oil for over 10 yeas. From the purchase process to the application and performance...Amsoil is 1st Class!

I changed my 2014 Infiniti QX60 over to 100% AMSOIL products. I won't look back.

Great oil, would not change for a different brand.

use this oil in my wifes 2014 dodge charger 3.6 great oil

I have tried many products in my lifetime trying to protect my investments from friction damage. I purchased a new 2002 1500 Chevy Suburban LS with a 5.3 liter engine and tow package. Was using a competitors synthetic oil and was very satisfied with the product. All the ticks and clicks that bother me were gone and the smooth running engine was great. The problem with the oil was that it was hard to come by locally and when it could be found it was very expensive and the wrong viscosity. I had to resort to ordering on line in five gallon containers and found that the oil was burning off about one quart every 15,000 miles due to heat. Specs. on the product indicated it could handle the heat but apparently it could not. An offer for an AMZOIL Preferred Customer came to me via e-mail so took advantage of the offer and ordered oil filter. Changed oil and filter using your products, started the vehicle and did not notice any difference but the more I drove the smoother the engine became. I could not believe the difference, so since then I only purchase AMZOIL products and will never put another product in any of my vehicles. AMZOIL is the best!

Love the extended change. 100000 so far on the car and the engine runs perfect does not use a drop of oil.

Used on my 2008 Toyota Tundra, great product and smooth running, motor runs quiet and cooler... Excellent.

As advertised fast home delivery

Great product! I use it in my 2014 Jeep Grand Cherokee with 92,000 + miles and it runs better than when it was new. Using the Signature XL 05W20 (6-quarts). I have 6000+ miles with ZERO oil consumption and it runs glass smooth. I LOVE all Amsoil Products!!

Been using Amsoil for YEARS. All my cars have gone over 200,000mi and NEVER used a drop of oil!!!

Awesome product ! Decreased the engine temperature by 12-15 degrees! Will ALWAYS purchase this oil for my supercharged truck!

Thanks Quick delivery

New to the 0 - 20 My Subaru calls for it. Should be good as all the other Amsoil products I use.

I only run Amsoil in my vehicles. I have never had a failure due to oil-related parts! Amsoil is the best protection. I've been using it for about 30 years now in all of my vehicles.

Aaaaaa+++

I run Amsoil in everything I own, from my Duramax to my ATVs. it has never let me down.

We have a fleet of trucks in our construction business and wouldn't think about using any other oil.

I have a 2003 S10 Xtreme pickup with the 4.3 V6 engine that is driven two to 3 thousand miles a year. Need a top quality oil that will be changed once every year. Amsoil Signature fits that need.

Great product will always use . Don't understand but cars just seem to run better . Enough Said
