hi Curt!
as some others have mentioned, the smoothness of the engine when
burning BioD is probably more related to the way BioD ignites and burns
than to the (much lauded) lubricity.
odds are your flat spot and acceleration changes are related to the
injectors getting cleaned out by BioDs solvency.
the commercially produced B99 i've been buying from the factory
lately has been going for about $4.20 for quite a while now, while #2
prices have been somewhat higher and are only just starting to come back
down.
cheers!

Finally found a bio-diesel pump in my area, put 7 gallons (all it would take)

Before I could get back on the highway I noticed the engine was quieter, just
like what happens with a quart of engine oil in the fuel. I think this is due
to the increased lubricity of bioD. Its been about 75 miles now and aside from
the quietness I'm seeing the flat spot in the beginning of the throttle go away
for which I'm very grateful. When I first got the car it would go away if I ran
a LOT of Diesel Kleen in the tank but thats an expensive way to deal with the
issue. I'm also seeing better first gear performance, easier takeoff I mean.
I *think* something had gotten gummy in the IP. I did a does of Diesel Purge
last summer and things were better for awhile but the frustrations returned. Of
course I commuted with the car 110 miles a day all last week which surely
helped but I'm well pleased with this. Also the Bio-Diesel I bought was only
about $0.06 more expensive than the cheapest diesel I can find. I wish it was
more convenient to my house, I'd use consistently. As it is I plan to fill up
there on Fridays for awhile to let the bioD do its work.
