ULSD vs Regular Diesel / Have You Noticed?
This is a question and not a statement... Almost all of the lube oil contamination can be traced back to soot. And in theory more soot is formed when sulfur is present in the fuel. Of course incomp...

Next door to the taco stand. Read the panel to the left of my message post block :)
If you had an older diesel, you could use some of that used taco grease for fuel:)
The question is directed at owners of diesel engines of similar type that have had extensive experience with both types of fuel. Low & NO.
While I don't have a ton of experience, I'm at other end of the stick but have done tons of reading. And have spent hours talking with a retired Cummins engineer. So maybe my post is more of a "book report" so take it for what it's worth. ULSD is not user friendly to mine at all. In my reading and many phone calls to oil analysis places questioning (weather to add two stroke oil or not) several have said that if they owned a newer (anti?) pollution machine, they would add a "spinner" or (search word) "spinner centrifuge oil filter". Removes soot down to 2 micron level. Which at that level, some detergent is also trapped. If you start researching them...first step is to find out how much oil pressure your spec's says you are supposed to have. If you don't have enough oil pressure to cycle oil into and out of spinner, useless to have one. YouTube has some vid's also. The retired engineer backs up his maintenance 10-15 percent. He also said most fuel pumped to the public in the US is at the 20 micron level. He didn't think overall additional fuel filtration beyond OEM was necessary, but he has an onboard fuel pressure gauge and replaces fuel filters when he sees a bit of restriction or 10 percent less mileage/time than what spec calls for.
Having said all that I thought one of the reasons for the new oil spec "CK" was supposed to help you guys that carry around extra 500 pounds of (anti) pollution devices? Wonder if you can buy carbon offsets for carrying around that extra weight?:)
