I went to fill with diesel at my favorite Chevron station, and I noticed the diesel pump said something like S15. I had no choice at the time, so I only put in 10 gallons, cause I knew I could get better stuff later. A guy at the station remarked that it was ****, and bad for the engine and injectors. I get the environmental part, anybody know the facts about it's effects on the engine?

My neighbor uses it in his Cummins as well. Don't know enough about modern Diesels to have a opinion on how it works in them.
My 6.0 Powerstroke liked running on B10 due to the additional lubricity in the fuel and I actually got better mileage with it than running straight ULSD with a friction modifier. If I remember correctly, that era of Powerstroke was only certified for B5 even though I ran a greater bio mix. My 6.7 Cummins is rated for B20 and I see no difference in performance or mileage between B20 and straight ULSD.

Thank you all, you guys are teaching me a lot. I am in Oregon, and the button on the pump said S15. Had never seen that before. I have a 2016 Duramax, so I better read the manual. My rig has only 3600 miles on it, and I have changed oil once, but not fuel filter. I better look into it. I need to find out how often the fuel filter needs changed. We got a foot of snow now. I can wait a bit. I don't drive it much right now.
S15 has NOTHING to do with biodiesel. it is the max sulfur content. And that is federally mandated and also mfg require diesels after about early 2000 to only use S15.
Oregon diesel will be 5% Biodiesel unless you fill at a pump that says otherwise, often "up to B20".
And the 2016 duramax manual says you can use B20.
Fuel filter life will show on the DIC. manual states a time duration or when it says 0% whichever is lower.

Todays new fuel systems do not put up with ANY water. The pressures they run now days will kill the pump or injectors in a heart beat.
I do not like the stuff nor do I use it when there is straight #2 for sale.
Todays modern fuel systems cost 15 grand+ to replace. "Do you feel lucky? Well do ya?"
Do you realize that much of the diesel you buy today as "straight #2" is B2-B5? and isn't required to be labeled as such on the pump. You'd be hard pressed to find B0. You've probably run way more B5 than you might think.
"In every state, biodiesel can be blended with traditional petroleum diesel up to 5 percent. At this B5 blend level, the fuel still meets the ASTM D975 fuel specification and does not require any additional labeling at the pump. Once retailers begin to sell blends from B6 to B20, labeling is required."

My state (Washington), and probably Oregon also, mandates a minimum of 2% biodiesel. They can add up to 5% of bio and still call it #2 diesel. No getting away from it.
