So every pump I see says b5 bio diesel. It may say up 5% bio diesel I can't quite remember. I looked it up on a website and it only listed like 4 gas stations in all of Texas which had bio diesel. I find that hard to believe when every pump I go to advertises bio diesel. My reason for asking this is because I've always used stanadyne lubricity additive and if stations have bio diesel now I was going to stop using it since it's not needed then.

I'm pretty sure all our pumps have b5. I've seen some with b10. I bet it's like ethanol. Most likely mandated by the government. At least biodiesel is a benefit unlike ethanol. I'm in Canada though so it might be totally different.

I have never seen anything about B5 where we fuel the trucks up. I will have to ask the station manager about it.

According to federal regs, if the fuel has a B5 or lower amount, there is no requirement to list anything on the pump saying it has bio in it. B5 or more, then there must be labeling at the pump to show biodiesel. Not the actual percentage is required to be listed. Many outlets that have B5 or higher just have stickers that say something like "between B5 and B20". This is similar to the E10 game. Stations are not required to show gas with ethanol levels of only 10%. Though many will only because of consumer demand for that info. But they are required by law to state if gas has E15 or more.

In France, diesel will go up to B8, was B7 until now. Not that many of you will fuel your car there though...

True, but I regularly get diesel that has bio levels of 10% or more. I just never worry about it. I have been using bio laced fuels for almost a decade now, year round, with no appreciable issues. Occasionally, maybe a more frequent fuel filter change in cold weather. But I have a visual filter bowl that lets me know when filter is just about ready to change and I can have it changed in 5 minutes. I just look for the lowest price I can get diesel for. When a person like me goes thru 20,000+ gallons of a fuel per year, price always matters as does fuel economy. And my fuel economy requirements in my commercial vehicles is much stricter than any government CAFE stuff. They are playing catch up to me.

B5 is pretty widespread in the US, it has the benefit of making our ULSD work in older and the newest injection pumps, notably the Bosch CP4 which was grenading rather quickly if used with regular #2 without any additional lubrication. Our diesel generally sucks in the lubricity department and the high pressure injection pumps were not liking it at all. Bio happens to be a great lubricant and carbon neutral in theory as well as a great detergent for the fuel system. Sometimes it's a little too good at cleaning though and will knock enough crud loose to plug a few filters after switching over. It's also a little harsh on rubber fuel lines that aren't rated for bio use.

This is what irks me. People say new common rail diesels run off of new fuels just fine, then you hear about the latest injection pump failing because it can't run off of regular diesel.

I suppose, but there are millions of diesels running around just the U.S. every day and fuel pump failures are not very common. Even when nothing is added to the fuel for lubricity and such.

Most places have gone to B11 here in Illinois. Missouri stickers say "Percentage between Bx and Bxx" usually 5 and 11.
I just changed fuel filters in my Powerstroke yesterday. I wasted my time. They were spotless, the diesel drained from the frame filter was clean and green. I do add either FPPF, Redline, or Opti-Lube every tank though. Can't say if it helps or not, but makes me feel like I'm doing something right.

There are some studies that show even small amounts of bio cause fuel dilution more so than what has been seen from straight diesel fuel.
