Can I run BIO

[onecrazyblackredenck]

I just found out there are many places here in knoxville that sell biodiesel. Does your truck have to set up for this? Is it ok to run? (dont wanna tear nothing up) does it get better or worse mileage? Smoke more or less? Do I use additive with bio? Do you reccomend it?

[Dave]

You should be able to run it. What percentage bio are you thinking about? you might get slightly worse MPG. As to the additive question how cold does it get there

[onecrazyblackredenck]

maybe 30 at the coldest..........What percentage should I look for, I didnt know there where different kinds, I know nothing about bio diesel........is it bad for the motor

[Dave]

Not bad at all. But it does act as a detergent, so you may want to have an extra fuel filter handy. Also i recommend changing fuel filters at 5K when you make the switch then go back to normal intervals

common percentages are B2, B5, B20, and B100 for premixed bio.

Of course you can mix it to whatever percent you want. But if its below freezing in winter i recommend that you stay at B20 or under

Biodiesel will not hurt the 7.3 and there is not any modifications that need to be done. After the first couple of tanks(if runnign B100) you will need to change your filters. I just did my frame rail one last night and even with all of the fuel dained from it it was 3 x heavier than normal.

I say go for it bud -- won't hurt a bit -- jus tchange the filters like the other guys have said!

[onecrazyblackredenck]

I thought there was only one fuel filter, on top of the motor, which I change every other oil change, 6000-8000 miles......Is there any advantages to running the different gradeS?

[Sciulli]

yeah on the 7.3 there is only one. I have a 6.0L. Different blends of bio are needed for cooler cilmates. Biodiesel will gel at much higher temps then regualr diesel. Normal Diesel fuel addtives do not work on biodisel(>B20 that is). The more biodisel you run the less btu/unit volume your fuel contains, since biodiesel has less overall. B20 has no effects(on winter properties or fuel economy) which is why alot of people stick to that blend.

Not only is it okay to run your truck will run better on Bio, it lubricates better, so after the cleaning process from the first two tanks your mpg will likely increase. I plan on making my own bio diesel this winter!! .60-.80 per gallon sounds a lot better than $3.35!!

i have a 97 7.3 heard that bio diesel might mess with o rings or the rubber hoses is this true and what do you guys think of the fuel meister
