Customer Ratings & Reviews

I had been running Mobil 1 in all my Mercedes but decided to try Amsoil due to loud noise coming from the top end of my wife’s 2015 Mercedes GLK350. The vehicle only had 35,000 miles on in, but sounded almost like a diesel when it started. Now the vehicle is the quietest engine I have owned with overhead camshafts. This is the 5th Benz we have owned in the last ten years and I had run Mobil one in all of them.

Great oil from AMSOIL as usual. Used on a 93 BMW, that runs quieter and smoother.

have 5 pre 2012 german vehicles currently using amsoil. have not had any oil related issues in over 10 years using amsoil. getting delivery to my house is simple. I plan to continue using on all my vehicles as well as other amsoil products for small engines and motorcycles

How does one review a motor oil after less than 1000 miles? I will say that the engine in my BMW 230i seems to run a little quieter, but that may just be in my head. It is certain however, that this oil meets all the specs for European turbo motors. That is a demanding task to protect that engine. I have confidence in this oil.

Ran it for a track weekend and it still looked amazing afterword and burned very nicely plenty of oil after the day

This oil has been great , been using it for many years in my hot natured Audi turbo cars with high demands, has performed very well and kept the top end clean (scope often)

fantastic oil,been using this since 2005 in my high performance subaru,got the rest of my family using it also so now i am a member,cant go wrong there,great prices

I contacted customer service to find out which oil I needed, and the email response was fast and accurate. I purchased the oil online and received within a few days. Used in conjunction with the engine and transmission flush, my engine runs smoother, more quiet, and feels less restricted/more eager to pull. Best oil I've used by far. I would 100% recommend AMSOIL.

Been using this oil for 10years now, won’t use anything else

Amsoil is unmatched as a product and as a company. They have integrity and a personalized approach to customer service.

Run this oil in vw tdi, excellent oil

Ams oil is only oil I use, this purchase is for my 2012 Mercedes GLK 350, runs cooler and I get better gas mileage with it.

Good oil for the price

My SL550 deserves only the best. I use SAE 0W-40 Synthetic European Motor Oil because I only want to use a true synthetic oil in my 2009 Mercedes Benz SL550. Other "synthetics" have additives that make them not 100% synthetic. Engine performs extremely well under all conditions. Will only use this oil even though manufacturer recommends a different brand of synthetic.

After years of saying,”someday I’ll give Amsoil a try”, I finally did it. My MPG went up! The website selector found the correct oil for my truck(not a common oil). I became a member and was quite please with the discount. Shipping was super fast and well packaged. I hat buying things online,but... this is the only way to go. Thanks so much.

Seems to make engine run quieter.

Good oil

This oil is great but it can be to thick and can use a thiner oil to balance it out for perfection.

Very good oil. recomend for evrybody!

This is it!! This oil meets Mercedes standards for oil. You found your product. This oil is great in European diesel engines. Living in Colorado and driving up the mountains the turbo gets hot, this oil handles the heat just fine. I use my diesel for long trips and around town driving too, this stuff holds up to all the abuse.
