Customer Ratings & Reviews

I purchased AMSOIL for the annual oil change for my 1993 XJ40 with the inline 6 cylinder. As i don't use this car on a regular basis, the annual oil change fits my needs perfectly.

Swapped my ecodiesel over and immediately could hear a difference in how smooth the engine runs. Came out much cleaner in appearance at oil change.

It is very strong in hot climate, lubricant pelicula breaks at higher temperatures than other types of diesel engine oil, I charge it around 5000 to 6000 miles

I know this is not the oil that I should be reviewing but I want to comment on this very important fact and occurrence. I took my motorcycle a 2015 BMW S1000RR to the racetrack. The oil filter was not torqued on properly and going down the straightaway in third gear at approximately 140 mph all of the amsoil synthetic oil that was in the engine came out through the oil filter gasket which was not seated correctly. Suffice it to say that once sliding around and turn one and having to change my pants I was able to ride the bike with no oil in it all the way around the three mile race track to get off the track. After thoroughly examining the engine there was no damage whatsoever. Amsoil is the only oil I use in all of my motors

Top tier oil analysis after running this in my Generation 3 RAM Eco-Diesel. I have used AMSOIL in every single thing I own with an internal combustion engine besides my airplane (not certified for GA) and it has never let me down.

The best oil i have ever used in my 2013 VW Jetta 2.0, I find for some reason with this oil and amsoil filter I burn less oil per change interval, only about half a quart or 500ml per 5000km, this oil is absolutely amazing, summer and winter

I've switched from Liqui Moly engine oil to Amsoil, and the results have been impressive. I send out oil samples for analysis every 15,000 miles, and since making the switch, both copper and iron levels in the oil have dropped significantly. The engine also runs noticeably quieter and feels stronger under acceleration. I still change my oil every 5,000 miles, and based on my experience, I highly recommend Amsoil. My oil analysis was done by Labstone I wish I could share the report here!

I like that it helps with oil consumption. The engine runs better with it in there. The engine makes less noise. Just a great product.

Car likes it ;)

Been using Amsoil for 25+ years, it always impress me.

This is the engine oil which I am using for last twenty years on my Audi and vw cars . It seems to keep engines clean , well lubricated and out of problems

This brand of oil is the best

Love AMSOIL products. Upset that I have to get product shipped to me since the Wichita, KS warehouse was closed for some reason.

One of the best!

I use 0W20 on both my Audi S5 Coupe and My Q5. Both vehicles are low milage and I trust Amsoil to provide 12 month of protection. I am concerned about the tariff war between the USA and Canada. I may have to look for a local product if Amsoil prices become too high

Amsoil is the best oil I ever used in my vehicles and motorcycle. I got 619,214 miles out of a 1987 Vw gas engine.

Use this in all my German cars I have six and they all run like brand new one even has almost 300,000 miles on it and I also use the motorcycle oil in the four bikes. I have one Japanese and three Harleys.

The project went very well.... It was thoughtful / Great idea putting disposable gloves 🧤 a paper vunnel & a window sticker.... WONDERFUL 😊

Been using this product for years with excellent results. And when testing has been done Amsoil has always compared very well against other products

I was put on to AMSOIL a number of years ago. They come out on top in the reviews I've seen. The delivery service is good. I've never experienced a engine problem using their products but I do change my oil regularly. One area that I can say AMSOIL products out perform others is in the 2 cycle mix. On others I had to keep rpm up or it would stall with AMSOIL I can set the thing down and it continues to idle and run smooth. I'm thinking 'good in one - good in the other'. Also it seems to keep the combustion area clean. I do have an old tractor on its last leg. I've used other oils and it just doesn't run well, with the AMSOIL diesel products I can still keep it going. I'm thinking AMSOIL is a superior product.
