Customer Ratings & Reviews

I have been using Amsoil for a couple of years now. It started with my 2012 Chevy Traverse. Chevy required that I use a oil that was partially synthetic. I started using this because my dealership didn't work on Saturdays and it was hard to get in for an oil change. Also I soon realized that I couldn't trust the quick change oil shops either. I have a shop that will use my oil and charge me a reasonable fee for changing oil that I can trust. I like that I can go for a year on the oil and it helps keep my cost down. I would like to add my brother uses this oil also. He has a 2004 GMC Yukon XL with over 250,000 miles on it now on the original motor. When he started using it he had around 130,000 miles on the motor and it was using about a quart of oil every 2000 miles. When he started using Amsoil it kept using oil until he had around 6,000 miles on the first oil change and it suddenly quit using oil. We are both convinced that Amsoil saved that motor. Him and I are using Amsoil in all of our engines as well other Amsoil products and are extremely happy with Amsoil and will keep using it

I started using Amsoil Engine Oil in a higher mileage (130k) V6 and have noticed less lifter noise on startup. The oil seems to have good viscosity after 3k miles which should indicate longer oil change intervals. I also changed all fluids (diffs, trans, transfer case) over to Amsoil and have been very pleased with how the drive train feels. Of course new fluid always makes it better but it seems to coast and accelerate better than ever so I think the fluids have improved the vehicle performance slightly. At this time I haven't noticed any drastic MPG improvement but I do think there's just a little more power.

Love how long between oil change

I 've used this oil for a long time never wanted to try anything else like oil with color in it I just wanted a truly good product thats why I stayed with Amsoil hasn't let me down and I recommend it to everyone

Love the different colored bottles. ONE oil change a year, at this quality, I'll take it. It's cheaper thank you think

I use AMSOIL 10-30 Signature in 3 vehicles,,and have an AMSOIL user for over 25 years. I use 10-30 Signature in all 3 vehicles,and AMSOIL Diesel oil in my daughters Class A motor home

Used amsoil for 20+ years. SS series is great for long drain intervals. All of my engines have many miles on them thanks to protection this oil gives.

my 99 acura is running great after oil change

Personal oil changes. I like the fact you don't have to do oil changes for a year or 25,000 miles

Love this oil it's the best

The oil is advertized for extended oil change intervals, far more than the manufacturer recommendation. Following manufacturer change interval of 10K miles will ensure my engine and turbo will be protected by this oil.

I use it on my ford vehicles. The product and lab reports on it speak for themselves. This is a must product if your vehicle requires it.

I used this oil in my cars, good performance and gas improved. I recommend 100/ I put in my Acura TSX real pure Synthetic

I highly recommend the AZO 0W-30 Signature Series oil. I have been using it since it came out and the 0w-30 SSO oil before that. This top of the line oil has kept my car running young, now at 449,000 miles.

Phenomenal

I am a high-mileage driver >1,000 mi./mo. I got so tired of going to get my oil changed every month. My truck has 2 skid plates underneath it that have to be removed for an oil change. From the time I left work and returned for an oil change was typically 1-1/2 hours. Now, It's every 3 months!

Excellent product

Have this in my 2007 silverado.Seems to be doing as advertised.No engine problems at all.Runs great......Will continue using this oil.No cold starting issues with it.

Changed the oil on our 2014 Lincoln MKX.

My order arrived on time and un-damaged. I use Amsoil in my Gatortail engine (Briggs) replacing the oil at 25-35 hours with a total of 550 hours on the engine. The oil holds up very well. When conducting maintenance on the engine the interior working parts of the engine are like new with absolutely no visible signs of sludge build up. I highly recommend the use of Amsoil products. I also use the Amsoil Marine Grease in the lower unit and that product holds up very well as well.
