Do you guys think it would be OK to run B-20 in my truck with my mods or would I be risking stuff and if so, what?

What are the signs to look for if something is going wrong (aside from the truck bursting into flames or not starting etc. etc.)

 

what is a B 20?

 

biodiesel, i filled my truck up with it and the next day had injector problems, they cloged my nozzles with crap, ive heard it can act as a detergent and clean crap up so it was either that or just bad fuel at that station. I wont run it again.

 

I run b20 every fill up with no problems. With B50 and b100 my fp will get low. B100 or B50 will clog the filter when you first start using it but you should be ok with b20. Just check your filter after a couple of tanks. I have never heard of it clogging the injector nozzle. The filter should filter it before it ever got to the injector.

 

B20 should be fine. I would carry a spare fuel filter incase it clogs up from the extreme cleaning action that bio does to the system.

When bio hits the cp3 and those high pressures it polymerizes (gets stringy) and can clog an injector regardless of how much you filter it. With B20 or less I don't think it will cause any problems as long as the station you're getting it from uses quality fuel.

 

I used B-20 ($3.50 a gallon) for the past 2 years, no problems. Get a good source.
Enjoy the French fries fuel.

 

I'm running 5% right now but i haven't ran it long enough to see a difference yet. We also just switched to 5% in all are farm tractors too and i think you can get better fuel milage out of it at least in the tractors. The guy we're getting it from said it'll clean all the crap out of every thing so we'll be changing fuel filters a lot at first but once we get everything cleared up we're going to switch to 20% bio. So from what i understand make sure you change you're fuel filter a couple of times after you start running it.

 

Bio is not all that it is cut out to be...YET. There is only 1 oxygen, hydrogen or carbon from the make up being similar to an abrasive plastic like compound. Common rail pressures have shown the possibility of changing the physical make up of the bio...and destroying injectors. There is a reason (even though they won't tell you) why none of the big three will allow 100% bio run through their motors...

I am sitting on the fence longer...

I have no problem running the stuff and I do in my older equipment.

 

Is biofuel a thixotropic fluid?

 

??????

I have no idea. Just info I've read about biodiesel. Inifidel knows a lot more about it.

 

I run b100...the cause of most failures is due to home brewers high water and soap suspended in the biodiesel.

 

Don M has found some interesting stuff in the injectors of trucks that run a bunch of bio...

I would consider bio having thixotropic fluid properties...but I am not sure that explains the phsyical change that "sometimes" occurs to it under HUGE pressure.

Its viscosity decreases with agitation, heat, flow etc...but I am not sure if pressure causes the reverse of it. My scientist days are long behind me...since I don't have unlimited time and budget to think anymore. My trade has become a comodity...lol.

PE's will be handed out in highschool soon.

 

So it seems to be the concensus that Pittsburgh's finest grease in my B-20 should be alright if I check the fuel filter regularly and let it clean my system out. It seems like any problems that would arise would do so at the B-50 or B-100 level but not likely to occur at the B-20 level?

 

Personally, I wouldn't run it Wiggs, just too many factors going on that are against you.

what is wrong with good ol #2 only?

just my opinion
