Best oil on market
Clayton C. –
I’m running this in my ’17 F250 6.7, all previous oil changes were T6. Schaeffer’s is supposed to be far more premium but honestly I think the Ford 6.7 runs better on Rotella. It seems to run louder on Schaeffer’s and this oil meets Ford’s specs. I bought Schaeffer’s because it was on sale here on Amazon for $6 a gallon less then T6, and because I was intrigued to try it. I also noticed that I get a hair better fuel economy with Rotella but its so small maybe its not worth mentioning. I’m going to give Schaeffer’s a little more time since I bought enough for 3 oil changes, but I’m feeling in my gut T6 will probably be the winner after I’ve gone through all the Schaeffer’s.

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.

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.

Some of the best oil on the market
Destin Wheeler –
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.

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.
