Grumpy said:I have a 04 1/2 Dodge diesel, and about all I have been running it in for the last two or three months is bio diesel.
I add about 6 oz of Howes in the tank, about every 3 or 4th fill up.
John In Detroit said:I have heard some interesting things about Bio Diesel. including that many Diesels can switch to 100 percent bio with little or no mods.
Will said:What percentage are you running?? Home-made or from the pump?
What is the point of the Howes?
MotherShip Captain said:One of the stations in the area (Idaho) advertises that their diesel now has 20% bio diesel.? They say it works on any diesel younger than 1995 or something like that.?

I can't speak for Dodge/CUmmins set ups, but for motorhomes Cummins has used and has no problem with B5. They've worked with B20 and see no significant problem but have not tested it enough to say go for it. Cummins, or it's dealers, cannot void your warranty for using B-20. If you have an engine waaranty claim and they can show that it was due to the use of B20, they can deny the claim, but your warranty is still in effect.
Will said:I have yet to hear of any difference in the way that biodiesel reacts with the varying sulfur levels in the new fuel. All indication that I have seen seems to say that biodiesel mixes the same with ULSD.
