Customer Ratings & Reviews

I have used Amsoil for a number of years and in a number of vehicles and have come to rely on what they do for the long life of motor vehicles and would not consider changing that view.

Use this oil in two of my vehicles and noticed improved performance all around over the years.

AMSOIL is an excellent product and I use it in all my vehicles and the boat. The signature series 0w-30 met/exceeded all the specs for my Alfa Romeo Giulia, which is what this most recent purchase was for. I love the shipping from AMSOIL it’s very fast and at a reasonable cost. I would definitely recommend going with AMSOIL for your vehicle even European spec ones. The signature series is the best oil out there right now.

Love this oil! Car runs a lot smoother than before!

Good stuff

Im a long time user of this Signature Series oil. I drive my cars until the wheels fall off so for me Ive had several vehicles that went 200K plus. For me it's usually something unrelated to the powertrain that causes me to get rid of the car/truck.

Best oil I have used.

I just recently accomplished the oil change where I used AMSOIL. Don't know how to tell if it is better than competitors. I do know it was harder than heck to get someone to do an oil change with me supplying the oil. For this reason alone, I may not continue with AMSOIL. If you change your own oil, I'm sure it would be fine.

Using Amsoil signature series synthetic 0w20. 1.5 liter turbo engine is demanding, my perception is that this oil will stand up to the rigors of this engine. Have been running Amsoil in my '17 2.7 liter twin turbo f-150 about 4.5 years with no worries.

My brother is a great ambassador of your product, My order value $450 -didn’t show up -re-ordered they customer service I was told she/Amsoil would make it right by sending me a gift. -didn’t receive any acknowledgment and when I recd the new order a container of oil had saturated the cardboard box. In closing , I don’t expect to hear back, but Your welcome

I haven't even considered another oil since I've found this. If you pair this with their filter it will double the life of its competitors

I have been using Amsoil products for 20 years. My 2012 Mazda CX9 has 136000 miles. Once a year, oil change and EA filter, runs like it did coming off the dealers lot.

I used to use Castrol oil until a friend of mine recommended Amsoil. This is a great quality oil and the only oil I use in my vehicles. Highly recommend

Best oil on the market. I get better gas mileage, my engine runs cooler and quieter. Always fast shipping that is packaged and protected second to none. Sign up to be a preferred customer and save a lot of money.

I want my truck to run forever trucks are very expensive

So I ordered 6 gallons of the 0W-20 Synthetic on August 24th, and expected to see the shipment in a few days, so I put it out of my mind. My card was charged the full amount that day. Three weeks later, I remembered that I had ordered it, and it hadn't shown up, so I looked up the UPS tracking and it said that the package had received damage, and UPS had notified the seller, and to check back for a tracking update tomorrow. I called Amsoil customer service and was told essentially that once the package goes out, it is up to me, the customer, and UPS to make sure it got to where it needed to go-they don't track the packages once they've left. I had called UPS to confirm that the seller was indeed notified and they said they had been. So whoever at Amsoil just ignored or sat on this information instead of taking the initiative and contacting me to let me know my shipment would be delayed and organizing a new shipment. The Amsoil customer service rep apologized, and said a new shipment would be organized immediately and she would try to have it rush delivered. She offered 20% off my NEXT order, so I would be forced to order from them again instead of offering a rebate off the delayed order to show that they wanted to take care of me. I told her I wasn't interested in the next order, I wanted to at least get the product I had already paid for ALMOST AN ENTIRE MONTH LATER. I got off the phone call expecting to see a UPS overnight delivery the next day. NOPE. 4 days later, my shipment showed up. 4 days. I live in AZ. I could drive to AMSOIL in about 4 hours. I don't blame UPS as I understand things happen in transit, and they notified Amsoil of the damaged parcel. I love this oil, but the customer service team takes the customer for granted because they know we have to buy direct. Very disappointed and luckily I won't have to go through this for another 15K miles, but when I do, I will make sure to call them every hour after they charge my card to make sure I get my oil.

Good oil

Build a few engines a year and amsoil is used in all. For break in runs, to daily driven, to high temperature run times. There isn’t other oil that comes to mine but amsoil

Amsoil is a must for hemi engines. Do yourself and your engine a favor and change to amsoil. No more hemi "tick". Prolong the life of your camshaft and lifters.

I switched to amsoil signature series today and I can feel the difference, truck runs so smooth now.
