If you love your vehicle this is the only oil to use. With oil being the life blood of your vehicle choose Amsoil. Best quality oil hands down. For 7k revs on my supercharged engine to my lawnmower. Nothing is better!

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.

Reviewed by Josh:
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'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.

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'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.

Been using Amsoil products for a few years now. Four different cars a Harley a lawn tractor a various small engines. I put a lot of miles on my car for my job and really need to rely on it. Everytime I do an oil change I'm reminded just how good this product is. The oil still has a nice color to it. It's not that black sludge you get from conventional oil.

I am not a chemist or engineer, so I cannot speak as to what's inside the bottle. However I am a mechanic and can speak as to what's inside a engine, transmission or differential. I've used Amsoil on and off over the years alone with other bands of synthetic and conventional oils. I've never used anything that didn't work. However, I've found good oils last longer. Being a fleet mechanic I change a lot of oil and get to see what it looks like under abuse. Amsoil always holds up. That's why I use it.

I have tried many types of oils and read a ton of reviews, which can be hard to decipher with everyone giving their personal comments and feelings. But hands-down without a doubt Amsoil is the best product out there, tested over and over again. I know this is the only oil I will trust in my vehicles.
Now, I wish Amsoil will create their own waterless radiator fluid so that everyone will enjoy all the fluids in their cars are coming from a
trusted source.

This is just one of Amsoil products that I use. I have used Amsoil synthetic oil for 20 years, and every time I get a new or used vehicle, I waste no time in switching the crankcase to Amsoil.

I have used other oils but was sold on Amsoil after a cross country trip where unbeknownst to me all the coolant leaked out of my vehicle. I never noticed because my engine never got hot. I drove all the way through the Great Smokey Mountains and hot Texas heat without my diesel engine ever getting hot even though I was towing a trailer. Great Stuff. Thats the kind of performance I like.

I have been a user of Amsoil since 2009 when I bought a VW car and your oil was the only oil I could find that did not void my warranty. I have been an Amsoil user ever since. My current Dart loves your oil. I tried this oil last time and so far it seems to keep my Dart purring. As Darts are known for eating oil like candy, this oil seems to help with that problem. The car also seems to run a little smoother on this oil. I do change my oil about 5-6K miles with Amsoil. I just had a warranty claim on my vehicle and there were no questions asked since I have been using Amsoil as an approved oil for Mopar. My husband loves engines and has switched to using Amsoil almost exclusively on most of his vehicles, small engines, etc.
