This is in my opinion the absolute best oil one can buy for all uses
I bought this oil for my tractor after my mechanic suggested it to me several years ago. It is more expensive yes but it is my opinion the best money can buy. I use it in all of my equipment and vehicles.

Great oil, but....
Swapped to schaeffers from Rotella 15w40 and noticed increased oil pressure, slightly better fuel economy, and a quite engine. I was quite impressed. It's really good oil, but... the downside is the price, I recommend going through a nearby sales rep as the prices are exponentially cheaper than buying from a 3rd party vendor such as Amazon, Napa, O' Reillys etc.

It is oil.
It showed up quickly. It was clean and unbroken. And I love how it is working in my truck. I thought it was cool when it was bright green. My oil is still kinda green so I know my oil filter is working with the oil.

Cant seem to get product
We use this oil exclusively with our Diesel Trucks because its good quality but for some reason I cant get Amazon to deliver it anymore. They keep giving me the excuse its undeliverable each time. So I guess I will have to get my product elsewhere.
