I order, 2 days later product is here. My vehicle starts better and runs quieter than what I was using before. I wouldn’t have believed it but it’s true. Excellent product and excellent customer service from Ashley Carte.
Bottom Line
Yes, I would recommend this to a friend.

Completely eliminates rough running issues in my 6.0 powerst
I have had 2 trucks with the 6.0 powerstroke that eventually developed rough running issues caused by stiction in the injectors.after changing the oil with amsoil 10w30 diesel oil both trucks started running dead smooth completely eliminating the stiction issue until I changed the oil at 5,000 miles and used t6 because I didn't take the time to order the amsoil.almost immediately the truck started running rough again. I immediately ordered 4 gallons of amsoil and changed it again as soon as ups delivered it.at which time the truck started running completely smooth again.so I know from first hand experience for a fact this stuff works and is the best on the market
I had to go a little longer between oil changes this past iteration. Travelling is sometimes a bitch. This has been the oil I have been using for the past 4 changes. I use my truck like it is intended. I need a lubricant that is proven to stand up to whatever I throw at it. There may be others that I can use but this is the best. If an outfit like Banks Engineering trusts it, I can too.
Bottom Line
Yes, I would recommend this to a friend.

Perfect package

Came with everything and perfect amount. Been recommending to all my friends.
Through oil analysis with Blackstone Labs I learned that the Rotella product I was using was showing premature viscosity thinning in my 2022 RAM Cummins. I was swayed by a gentleman in a diesel truck forum to check out Amsoil. Well let’s just say after much reading and video watching and switching to Amsoil in my Diesels (Cummins and Duramax both different weights) I’m highly impressed with the company, engineering, and testing they put into their products. I would highly recommend researching YouTube, Google, and the forms and learn as much as you can about the AMSOIL company. You’ll be impressed, I know I am!

Great product and great price when you are a preferred customer. I have a 95 F-350 and a 15 F-250 so I spend a lot of money doing oil changes. Very speedy delivery!!!!
I have been a loyal Amsoil user since 2008 and this has been the oil of choice since I purchased my 1999 Ford F250 SD in 2010 with 91K on the odometer. The truck runs just as well today and when you look in the valve cover it is clean inside. Great oil!
Bottom Line
Yes, I would recommend this to a friend.

Oe products are excellent. Been using amsoil for years.
The amsoil products i ordered arrived on time (actually earlier than estimated) and came well packaged. Everything worked great and as usual my engine runs quieter and cooler.
My only problem is twice now i have made orders and not recieved the free gift advertised on the website.
I recently changed my oil to the amsoil heavy duty 10-30 for the newer Cummins engines and surprisingly I noticed the engine is quieter and my mpg went up a little bit .
