Exactly what I ordered and came before delivery date which is very good

Good product and service

No oil is better—none! I have used this product since May 2020. My diesel engine purrs like a content kitten, and I have gone 15K miles between oil changes.

I have been using this oil in my 2015 3500 Silverado with a Duramax diesel. I started using the oil at 10,000 miles. I now currently have 198,000. It doesn’t use oil and it does not leak oil. I change the oil every 7500 miles. Absolutely love this product.

Great oil to use on all your toys !

This is seriously the best oil on the market for gas and diesel trucks. Comes in just a few days. I will always use Amsoil

Amsoil is an incredible product that really delivers both in performance and customer service. I highly recommend all of their products.

Best oil to use.

We use it because it's the best stuff on the market.

I use this oil in my truck and there is a noticeable difference in hot oil pressure. With other oils the hot oil pressure is about 38 PSI and with AMSOIL 15W-40 the hot oil pressure is about 42 PSI. The cold start valve noise is noticeable quieter with the AMSOIL than with other oils.

Been using these products for over 20 years highly recommend best in the business AMSOIL. We got out of a 89 Ford straight, six 450,000 miles. it actually still started, but motor had no more power

Great oil! I’ve been running in my 2017 duramax since it was new! 200k and going strong!

I absolutely love the protection and performance from amsoil. My truck runs so much better and actually see a slight increase in mpg since switching to amsoil.

My 97 power stroke always made a lot of deisol rattling noises, especially when cold..Amsoil made it quiet and ran much better...I pulled a heavy 8 k camper, 2 k miles and I am sure fuel milage was better.. definitely have mo power...in the big picture it's cheaper to use Amsoil.

I highly recommend this oil for any diesel platform! My 2014 6.7 Cummins loves this oil!

Loved the kit! Everything needed was right there in the box for me. Definitely worth the extra money. Thank you.

My shipment came on time without a hitch!! Thank You!!

Excellent motor oil

This is the 3rd diesel truck I have owned over the past 20 years. I started using this oil after being re-introduced to the newer and better way to access getting Amsoil products. I have been a long time fan of Amsoil, as I was in the racing community in the 60's -2000's running USAC several divisions and the NASCAR Modified and Super Modified divisions. I had Amsoil as a sponsor for many years of that time period. I stopped using Amsoil after racing due that it was so difficult in finding someone who sold it and would not want to sell you large quantities, if you wanted to buy if for a normal consumer need. Once I found that I a general consumer was able to purchase it from your website and become a discount customer I was all in. I did this in 2015 and have converted all my vehicles to amsoil products. This Diesel oil is great as it has reduced running temp of my motor and turbo, the coolant has increased the cooling quality and has the additive that i no longer have to buy what Ford wants to regen the coolant due to a mental degrading in the engine and cooling system. I also use the Amsoil micro oil filter for each oil change. The truck has just turned over 170K and is still running great. I change the oil every 20K with filter. The truck is a 2012 Ford F350 Super Duty 6.4 Powerstroke Diesel.

I have been using this in my truck since 2018. I like the quality of this over the Motorcraft. And it is actually less than a dollar more per quart the the Motorcraft full Synthetic.
