Customer Ratings & Reviews

Love this oil and the convenience of ordering online and shipped directly to my house.

Some years ago when I worked at Ford in Engineering I had the opportunity to meet a Sales Engineer from Shell oil. I asked him about this new fangled synthetic motor oil. He told me "Ed, its the greatest thing since canned corn". He also told me that at the time Shell didn't even have a product on the market. He also said that because it doesn't break down all you needed to due at oil change time is only change the oil filter and add a quart. You don't need to drain the pan. (Not that I've ever done this). Living in the Florida heat with an 86 Corvette an 83 El Camino and 2012 Cadillac which are all high mileage I use the 5W-50 because I'm sure by now there is a lot of clearance in the rod and main bearings. Good stuff.

Fast shipping and good product

Bought for my new used Honda CIvic with 60K miles. Oil life is at 70% now. Bought this in advance for my next oil change. Waiting for the Amsoil oil filters to come back in stock. In the meantime, the product was delivered immediately. Can't wait to try it. My son swears by Amsoil.

After people commenting how much quieter and better running their engines seem using this compared to other premium brands I thought I would give it a try. Put it in my 2021 Tundra and didn't notice engine or drivetrain or anything smoother or quieter than what was already in there(a major oil company synthetic). I am sure it is doing an excellent job lubricating but I notice no difference in how engine feels or behaves at startup, accelerating or anything. I generally change my oil at 5000 miles so SS certainly overkill but wanted to see if the hype was real. Also I don't understand why this doesn't carry an API License - I'm sure it meets the spec but why not Licensed? Won't buy this product again but may look at the API Licensed oil that you sell.

Works well.

I had been using Pennzoil Ultra prior to using Amsoil so I'm starting from a great oil. I believe the Amsoil product is slightly better than Pennzoil Ultra and I have had great success with Amsoil in my 2017 Jeep Grand Cherokee. I also used it in my 2012 Chrysler SRT-8 (5-W40 grade) with great success also. I feel this is true synthetic oil offering better shear and wear protection than all others. It's worth the price difference to me.

Ive been using Amsoil in our vehicles for years. It is so convenient to only have to change oil and filter once a year. By skipping the extra oil and filter changes each year I am actually saving money. What is most important is saving wear and tear on the engines! Keep up the great work, AMSOIL!!

I bought a brand new 2021 Infiniti Q 60 it had 18 miles on it I immediately changed it to Amsoil this oil immediately made it run smoother and quieter I recommend this oil to anybody that has a running motor.

Been using Amsoil, exclusively, for decades, in many vehicles. Never one oil related issue. Currently have a 2020 Ram 2500 6.4 gas engine. Those engines are known for cam/lifter issues. Most "tick", some experience cam and/or lifter failure. My truck has 21k miles on it so far. I change oil & filter every 7k miles. Engine is not showing any sign of typical failure. No tick whatsoever. I have been an Amsoil dealer for 20+ years, and mostly only for my own needs. Amsoil is the best IMO. Also, check out PROJECT FARM on YouTube if you need further proof.

Definitely worth using if you wish to extend the life of your engine. I've used other motor oils in my 2016 Power Wagon, but I won't use them any longer regardless of what the shop recommends. My truck has a little over 130,000 thousand miles and she still sounds and runs just like she did when she was new.

Just open the box and examine the filter. You will know why you’ll never waste money on anyone else’s filter again. Durable seal and solid construction. It stands out.

I'll put it like this. When I buy my dream car I will swap all fluids to amsoil from day one. YOU WILL NOT BE DISAPPOINTED.

Have utilized Amsoil in my vehicles for decades. Very happy with the results.

I have used OW-20 Signature Series oil in my truck ever since I purchased my Truck back in 2014. That oil has never failed me. Every time I change at 15k intervals, it continues to look like new still. I wish someone turned me onto Amsoil years ago.

Wonderful

Best oil out there period, viscosity holds up the best of all the other synthetics

Saving money is making money at only needing one oil change per year. Plus the added performance is noted especially in MPG.

Good product, drastically overpriced.

I have friends who have used nothing but AMSOIL products in their vehicles and have gotten hundreds of thousands of miles out of them. This is the first vehicle I've owned where I have started with the oil and air filters from brand new. When I get more miles on my truck, I plan to replace all of the fluids with AMSOIL products - transfer case, transmission, etc. It's a little pricey, but it's actually saving me money when I only have to change the oil at 25,000 miles. When I place my order, it's been pretty incredible that a box arrives at my door the very next day!
