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.

Tks again AmsOil, over 500,000k and still rattling away!

I've used this oil in 3 Mercedes. And have had the used oil tested annually. Always great wear results

I accidentally ordered the wrong weight oil through your website. I went back to your website for return/refund procedure. Your website sent me a CRM number and address to send product to. I shipped it and waited. I waited approximately two weeks for a notification of refund. I didn’t receive anything so I accessed your website again and used your chat service to ask about my refund. The person I was chatting with asked for my tracking number. I told the person I had a CRM number. The person asked me why I had a CRM number? I said that is what your website sent me. How would I know why I was sent a CRM number??? I then gave the person my tracking number. That person then said they’d call the warehouse I sent the product to. The person then said the warehouse called me and I did not answer the phone. I didn’t have a message in my voicemail from them? They called me and did not leave a message so they obviously just gave up. Did not try calling me again or leaving me a voicemail??? So the person found my returned product so they proceeded to give me a refund. They only refunded me 145.00 when I actually paid 200.00. I called customer service back and the person I spoke with talked to your accounting department and found out I paid to much for the product I ordered from your website so the accounting department needed to refund me another 45.00. As I said in the title of the review your product is good but your website order/return process needs a lot of attention! In the near future I need to order more oil, coolant etc. I am questioning whether or not I want to go through the fiasco I went through again! I want to make sure I am paying the proper amount for the product and if I have to return anything I don’t want to go through the same frustration I went through! Phil

Outstanding oil

I leave it 12k miles and still feels better than any other brands at 5k

After many oil analysis , this Mid Saps 5w40 is what the masses are running in the Jeep Ecodiesels. The FS is recommended but after the testing , I have switched to the MS and it is the best oil for these engines.

I have a 04 Jetta 1.8t, been running this since the day I got it. I do a lot of high spirited high RPM driving. I have overheated my oil to where my turbo started blowing oil. I installed a larger heat exchanger and since then I have yet to blow oil. Never replaced the turbo.

As always, great quality engine oil.

Great quality engine oil!

Have been using this oil in 5 vehicles including 2 motorcycles over 25 years with excess of 300,000 miles without a single engine issue. In sub freezing temperatures starting was never an issue. Yes I definitely recommend and will keep using Amsoil.

Have used this in my VW Diesel since it was new, now has a 100,000 miles on it, I have oil samples done, they say I can run it longer, very little wear in the engine

This oil for euro is amazing does what it says and more just wish price was about half way to much for this oil

BEST!

Some might say, “it’s just motor oil,” but I can tell my Ram Power Wagon is running better. I wanted to run a premium oil in this truck. I do a lot of back country off-roading that demands my truck be in tip top shape. My rep, Nathan, is a great ambassador for the company. I received some goodies (funnel, decal, gloves, and oil change sticker) in my shipment and that shows to me that this company is above and beyond what you will find today. You guys gained a loyal customer!

I have been using Amsoil products for decades, and I have never had an oil-related problem with any of my vehicles. But, this time, for the first time, I decided to order the kit, including the filter. Unfortunately, the filter was incorrect for my application, so I went elsewhere to buy the correct one - I was knee-deep into the oil change on a Sunday when I realized the filter was incorrect. I am sure if I inquired on Monday, I would have either received a refund for the filter or been sent the correct one.
