Customer Ratings & Reviews

Best oil that money can buy, I will definitely be an AMSOIL customer for life.

I use this in an older Z71 truck that has the 5.3 V-8 engine with 200k miles and most of these engines have lifter slap for a few seconds after start up but with this oil it doesn't seem to take as long for the slap to quit.

I started using Amsoil when I didn't have a garage so I wouldn't have to change oil out in the cold. These days I use the OE oils and just change oil when the maintenance minder says to. Too soon to tell how this is protecting the engine. Ask me in about 10 years or a couple hundred thousand miles.

GREAT OIL ALWAYS HAS BEEN NEVER HAD ANY PROBLEMS

I use this oil for our daily driven family car and it has worked great. I've used it almost since we got the vehicle so looking forward to seeing the long term benefits Amsoil is known for. I also purchased because I don't necessarily need long interval oil like signature series as well as more mileage. We use the car maybe 10k kms a year at most. Also, Its cheaper for this full synthetic than buying at a parts house locally. It in many cases is the same or cheaper than semi-synthetics. Great stuff.

I like the Amsoil 5w20 because of its high quality and because of the money I save from not having to change my oil every 3,000 miles.

I used this in my 2010 Camaro RS 6CYL. I believe that amsoil makes a quality product. I also use their Z-Rod 10w40 oil in my Dune Buggy which has an air cooled motor in it. Again quality counts !!! So far I have nothing bad to say about their products. I would recommend it.

I've been using Amsoil fir s few years and it is such a great product. Mileage increased after my first oil change in my Jeep I recently purchase and this was the first oil clange with Amsoil .

I've been using this in my 2015 Nissan Versa for over 30k miles. I drive a lot for work and Atlanta traffic can be pretty unforgiving. Since using AMSOIL, I've had zero issues with my car in traffic and on the highway. I'd absolutely recommend this product to anyone considering switching to synthetic oil.

Amsoil makes great products! I use this oil in a 2017 Ford Explorer xlt 3.5 NA. It runs very smooth. Keep up the great oils Amsoil!

I've used the OE line of Amsoil in a handful of vehicles now. When I've disassembled Motors that had Amsoil the internals are spotless. I've never seen crud buildup in the oil pans when using Amsoil oil and at intervals the oil always seemed cleaner than other brands. I always pair this oil up with an amsoil ea oil filter.

If it's from Amsoil I trust the product. Yes, a bit expensive at times, but the value gained from using the products in my opinion makes it worth the cost.

I have used AMS oil for 7 years now since I found it and I'll never go to another! Have put in motors with 400,000 miles and cars with 16 miles! No substitute

Fantastic quality oil. Easy on the wallet . Don't let the OE name fool you into thinking this a low grade product. This oil has been tested just as good , if not better than the other popular hydrocracked group 3 base stock synthetics on the market. This is perfect for daily driver vehicles . Be sure to match with a high quality oil filter made for synthetic oil . Remember your oil is only as good as the filter you use with it .

I have a truck with 295k on it, and still running strong. Thank you Amsoil.

High quality oil and will the membership its cheaper than buying in local stores than any other full synthetic oil

Knowing you have the best protection in the world market and on going research to improve and create new products.

I've been using this oil since truck new.. I am averaging 12.2L /100 km... Not bad for a 5.0L

I've been using Amsoil for around 6 years now and I've never had a complaint about their oils or their customer support. I use their oils in 2 Harley's, 2 Ram trucks (gas and diesel) and 1 Jeep and couldn't be happier with how smooth they all run and the level of great customer service I get when placing the orders. I honestly believe all oils are good, but I feel that Amsoil is the best - hands down. Vehicles are expensive to replace, so even the best oil, whatever you think it is, is cheap insurance.

My daughter's 16 and she noticed the difference in her Honda civic. I now use Amsoil in all of my vehicles.
