operating a 6.7 on B40
Used to be the case that B20 was the in your face renewable energy number from FORD.
No one ever explained by B20 and not B30 or B40, etc.
I speculated it had to do with emmission goals....I was wrong.
I poured some b99 in my low tank on my way to the fill station....calculating I would be at b40 based on the fuel already in the tank.
My observations...with B40...when you get to about 25000PSI of requested rail pressure....there is a faction of a second delay with the catch up on the actual rail PSI number. normally, with B20 and below...there is no delay.
This could be due to cold weather....not sure.
So...moral of the story...dont recommend more than b20 in a CP4 6.7.
Dont Know if the new wiz bang DCR pump will care on renewable fuel limits.

I wouldn't run B-anything in mine, too much chance of water, and other issues.

I've tun B20 in my 6.0 for decades, well over 190k miles worth. I'm running B20 in my 6.7 now. Never had the first issue with it. In my area, it seems to be cheaper than any other diesel, and the truck seems like it runs better on it.

Back when I talked to the car wash chain store fuel manager, she told me that the two distributors they buy from sell anywhere from a B2 up to a B5. I run K100D+ every tank so I don't stress... plus it adds needed lubricity for our CP4s.
They do not require a fuel up to a B5 to labelled as such.

"B1-B5: Does not require a pump label. ASTM announced in 2008 that biodiesel blends up to B5 perform and are handled the same as straight diesel fuel. Many retailers offer blends up to B5 in varying amounts and do not need to label."

I think everyone needs to realize is that ULSD fuel is, by itself, hygroscopic which means a substance that tends to absorb moisture from the air.

"...deal with the everyday problems that middle distillates can cause—in today’s case, the unstable nature of fuel. Ultra-low sulfur blends of fuel are more hygroscopic, meaning they like moisture much more than their predecessors, but unfortunately can’t hold that moisture as well, leaving stored fuels susceptible to water entrainment, microbial contamination and corrosion, thereafter."

One more post on the B2 to B5 blended fuel subject (no requirement for it be marked at the pump as bio-diesel).
"Most engine and vehicle manufacturers allow biodiesel blends in concentrations up to five percent provided those blends meet accepted (ASTM) fuel quality standards. (Biodiesel blends are mixtures of petroleumbased diesel fuels and fuels produced from soybean oil, waste cooking grease or other organic matter. These fuels may contain biodiesel in concentrations ranging from two percent to levels approaching 100 percent by volume.) To ensure proper quality, consumers should use only biodiesel-ULSD fuel blends that are properly mixed by a qualified biodiesel blender. Consumers should not create their own biodiesel blends by adding biodiesel to ULSD fuel in a vehicle’s fuel tank."
https://www.agc.org/news/2010/07/26/...ad-uses-summer
- ULSD is produced through a refining process known as severe hydro-treating. This process may cause the fuel to be harder to treat for cold flow improvement. It may require more #1 fuel or more or different additives to meet cold weather needs.
- ULSD is more hygroscopic than LSD. This tendency to hold more dissolved water may have negative effects on cold weather operations and may increase corrosion.

- Because ULSD is hygroscopic, it absorbs moisture from the air.
- Reduced levels of lubricity.

Not sure but they add that little bit in to help with the reduced lubricity of ULSD fuel. Every little bit helps in today's high pressure common rail fuel systems.

straight diesel in zip code 21701 (home) and straight diesel in zip code 85706 (tucson, dads house where I am at currently).
Thank goodness.
I have found the B20 contains less energy and therefore produces more soot IMHO and therefore more frequent regens.

since fuel is thinner than oil that would make sense…..I wonder if you have fuel lube additives in the fuel would that help get more lube to the cylinder walls
