I moved to southern illinois for work and i live in a ruel area and all the gas stations in the area sell only bio diesel do I need to worry about burning this fuel in my truck.

my truck is a 1998.5 24 valve 2wd with a auto trans, no mods except for air dog fuel system, I have notice a drop in fuel mileage Im only geting around 17miles per gallion.

 

I wouldn't worry at all. A friend of mine home-brews bio and I've run as much as 50% with no problems. Not sure about the drop in fuel mileage, I don't remember what a got when I ran it. Its probably due to winter blend fuel.

Bio is a good detergent and will clean out your fuel system. You may need to change your fuel filter after running it a little while.

 

i was just curious....what do they charge per gallon of bio there?

 

fuel is going for 3.19 a gallion theydid start adding winter additives to there fuel i didnt think about that it could be the reason for the change fuel millage

 

I ran exclusively bio in mine for about 3 years, until the place stopped carrying it. Now whenever I find it I fill up.
It ran great and I never noticed a milage difference because of the bio but I did notice a drop in the fall. The manager of the fuel farm told me that they would cut the bio with kero to keep it from gelling and that kero has less btu/gallon so i would notice a decrease in milage.

 

I read a study where bio adds a good bit of lubricity which is good for the VP. That said, bio can mess with rubber fuel system parts. Old diesel Mercedes can have problems with various types of veggi oil mostly because of water & trash due to incomplete filtering.

 

no worries other than cold weather and fuel gelling.
when its warm enough I normally run B100 that I make.

Bio is has FANTASTIC lubricity. I got very slightly less fuel efficiency on b99, but with anywhere from about b20 to b70 or so I found that I actually gained fuel efficiency. I have speculated that the bio was acting as a catalyst to burn the petro more efficiently.

Bio is a solvent, though, and will clean all the petro deposits out of your tank and these deposits may plug up the fuel filter the first and maybe the second time you run it. Also, bio has significantly less energy in it. It burns much cleaner, so you don't take the penalty you would expect, but since there is less waste heat due to efficient burn, expect more laggy turbo spoolup. Very little smoke, too.

PS I think usually the additive used for winter blend is kerosene. That's what my local supplier was using.

 

Thankyou for the info it was very helpfull.
