I see B100, B20 B99. So which is the right fuel for your truck?

I am assuming that your using the wrong term , for your truck , or mine ?
For any truck & blend , carry a spare fuel filter , the bio tends to clean out the system , plugging the filter , so having one with you , can save a tow .
As far as which blend to use , it depends what you are trying to accomplish ?
For performance , around 25-35% bio , bio has more centane , but a little less BTUs .
Less emissions across the board , more bio less .
No difference between B99 & B100 , except the blenders credit [ which you can not qualify for ] .
On the big upside , more lube for your VP pump .
As for using in the newer common rail systems , lot of info showing problems , mostly at higher blends , above 20-30% .

B20 should be safe.

B100 seems to be the only fuel in my area. But it's almost $3.00 a gallon. would running 6 gallons of B100 and 24Gal. of #2 Diesel be the same as buying B20?

The B numbers are the percentages of bio , B99 means 1% #2 , B20 means 20% bio .
So your right 24 gal #2 + 6 gal bio = is B20 , or close .
