Well this is a first for me.

When we say todays engines, is that to imply only engines in the last two years.... My tractor is (07) and they told me because of todays ULSD fuel I had to add in several ounces of Power Service additive per fil-up, I now use OR diesel but still add in the additive.................

In my experiences I would say diesel engines falling under the EPA guidance based on HP, 25 and above. For those, this has been going on for a few years, 5 or so.

I burn ULSD in every diesel engine I own (6) without any additive other than Gel prevention in Winter.

If by saying "OR" fuel you mean dyed red fuel, it's the same fuel as "clear", simply has a red dye to designate that it is being used "offroad" and thus no road tax. No specific additive required.

The last few years I don’t even have to think of Power Service anymore.



Whenever I get fuel delivered the driver dumps a jug in for me.




That way it gets done with every fill and I eliminates my OMS (old man syndrome) from trying to recall if I did it or not.

Even my old 1984 'Bota smoked less when they switched to low sulfur fuel.

Assuming it's low enough HP to avoid Tier IV requirement?

Oh c'mon, tell us what oil you put in 'er! Don't be shy, lol.

But another thought: The instant "blackness" of new oil in diesel engines can also be affected by how thoroughly you drain the old stuff out. IE, one half cup of residual sooty black oil left in the filter housing, pan, or block can make a fresh gallon of new oil look dirty right away once mixed back in. If your machine has a well designed oil system and you drained it out on a 120 degree day (YUCK, btw), I bet it drained very well and you got all the old thin junk out.

I change my oil annually. My first tractor - Ford 1700 - would have black oil after an hour running on a fresh oil change. The oil on my M6040 looks just like new oil - after a year of use. I use Rotella 15W-40.

deezer - you may have a very valid point.
