Best oil for emission sensitive vehicles

Use on my stock 2012 duramax with over 100,000 miles. No issues with dpf or other emission systems. With oil analysis, it holds up great for around 15,000 miles.

Definitely recommend Amsoil over any other brand

I travel a lot fishing bass tournaments all over the country pulling a 21 foot bass boat and I immediately noticed a difference when I started using Amsoil in my Ram 2500 diesel. Engine runs quieter and smoother. Can't say enough good things about Amsoil products.

I am a long time user of many Amsoil products and am very happy with all of them. I never worry about wear in my Duramax with Amsoil Max-Duty Synthetic. I was convinced that Amsoil was a far superior lubricant after reading about Amsoil's initial development. This was high-tech before high-tech was common outside of military applications. It took real vision and perseverance to develop synthetic lubricants that are truly affordable.

Measurable advantages!!!

Love Amsoil products. I run their lubricants in every oil reservoir in my truck. I don't have a temp gauge on my crankcase oil, but in my transmission, changing to Amsoil brought the temp of the oil down a measurable 10 degrees. that is significant.

I find their products well worth the money, their filters well built, and they ship promptly. It's not a hard decision to make.

Only the Best for My Truck

Been using this since the original oil was changed out. When I get the chance to talk of how I feel about what is required to make a Diesel engine to be environmentally compliant, (which I'll hold my opinion). No matter how long or short a conversation is, the one question asked of me is what oil am I running? After answering Amsoil, their response is usually, I'm running the best, or if someone is another brand loyalist, their response is it's one of the leading oils out there!
After reading and watching videos on Amsoil, it was a simple choice!

I would highly recommend this product

I run this oil in my 2002 Dodge Cummins. I've been running amsoil for the past seven years now. My truck couldn't be happier.
