[Vwdiesel] Jet A

[decker at toledotel.com]

Hi Justin;
    I don't know anything about TDI.s but I know that our N/A 1.5 and 1.6
motors don't run with as much power on the new ultra low sulfur diesel. I
don't recommend it because it would be embarrassing if you get caught but
about 3 years ago I ran across some home heating oil. A friend ran it in his
Dasher with it's N/A 1.6 and it ran smother with more power. I don't think
it changed the mileage much. This USLD is crap for power. I'm going to get
my turbo setup on my 1981 Dasher 1.6 soon.

Going to pass on some info concerning Jet A in TDIs. Have ran about 25
gallons mixed in various ratios thru my 98 Jetta. Two things I noticed was
that there was a noticeable decrease in fuel economy and a change in the way
it started. It wasn't as rattly on start and didn't seem to start as
quickly. Since I was fueling out of 5 gallon jugs I do not have a hard
number on what the decrease was. It was like running super winter blend
fuel. Here is the specific gravity numbers from the back of the Biobore JF
jug.

JP4 6.363 lbs/gal
Jet A 6.714lbs/gal
#1 D 6.827lbs/gal
#2 D 7.060lbs/gal

On certain turbine engines there is an adjustment for specific gravity so if
you were running a different weight of fuel you could change fuel scheduling
to make it run better. Wonder if there is a way to do that on the TDI
engines.
Justin
