Average MPG on biodiesel?

Question

Im thinking of getting an F-250 diesel truck (older) that the owner claims to get 18mpg on diesel. My quest is to use biodiesel and my question is if the mpg are the same, more, or less? Thanks!

Answer 1

I only got 22mpg, but I was using a 1976 MB 300D that needed a tuneup bad. Biodiesel yields almost the same milage - sometimes a little more, sometimes a little less - than synthetic petroleum based diesel aka "diesel"

Answer 2

When using B100 in my 300SD mileage goes up from 34 hwy @ 80 mph to 36mpg @ 85 mph.

However it cost nothing for me to burn wvo,and get 34 mpg.

Answer 3

I have a 2006 6.0L Ford Powerstroke Diesel. I am using a bio diesel blend in it right now 80% bio diesel and 20% regular diesel, my mpg's are about the same in town I am getting 16 to 17 mpg's and on the freeway 19 to 20 depends on how heavy my foot is. I want to go to pure B100 and will most likely start doing that in the next few weeks. I started at a B20 (20% biodiesel) blend and every three months went up to a higher percentage of biodiesel. I recommend if you go to biodiesel to start with blends so that you can see how you’re motor will react to biodiesel. Most of the time you won’t have any problems but just in case you want to be safe not sorry. Also if it is older than 95 you might want to replace the fuel lines biodiesel is notorious for eating through the old rubber fuel lines. If its newer than that they should be fine. Hope this was helpful.

For the most part it will not change significantly. What will change is the amount of food biofuel proponents take off the plates of the poor because you are using their food to power your god dam trucks. Don't believe me? Do some research on where biodiesel and other biofuels, especially ethanol come fom. Hint: It ain't some magical fuel plant. It's more like corn and other food-producing biomass that is being diverted from the food supply so you can drive your gross polluter to WalMart to buy cheap Chinese c**p that was delivered 10,000 miles to that store through a transportation network that is run almost exclusively on diesel fuel.

Answer 5

The mileage on bio-diesel should be about the same as of the petroleum product.  It may be a little more or a little less.  It all depends on the size of the molecule of the fuel you are using.  The bigger the molecule, the more energy in a gallon of the stuff.  The smaller the molecule the less energy in a gallon and the fewer miles the gallon will carry you.  

When Otto Diesel first developed the engine that bares his name, he intended it to use peanut oil.  This was in about 1880 or so.  He had a factory that made steam engines, and had lathes and milling machines to work with.  The diesel engine can run on a variety of fuels including waste motor oil, stale oil from a fast food restaurant, corn oil, olive oil, peanut oil, or crude oil from the oil well.  Even lard or Crisco can be heated and then fed to a diesel engine.  If the exhaust from a truck smells like French fries, you know where it came from.

Now for the short answer.  The MPG will be (about) the same.
