What kind of MPG to expect on 1999-2001 Jetta Turbo Diesel?

#11

Everything is scewed in Atlanta. Hot is longer and the cold is not
colder. Winter here means about 3 days in a row where it does not get
above freezing sometime during the week. I have not seen the label
winter diesel fuel but given the amount of 18 wheeler traffic I
suppose that a trucker would not want to fuel in Atlanta and freeze up
in Kentucky.

Well when it dropped to 20 below here in New England, the mileage showed a
dramatic drop. Now that the warm weather is here, the mileage is right back
up there.
The local stations sometimes advertize "Winterized Diesel" in the colder
weather. I believe (but in no way am I expert) that the thinners used in
winter drop the cetane level and contribute to lower mileage. I can't
believe that Atlanta has winter. ;-)

I have seen no significant change in mileage between winter and summer
where I live in Atlanta. I know they change the mix for gasoline but I
am not so sure about diesel. I am getting 50-51 when I started to set
the cruise at no greater than 70. Your mileage drops significantly
with increased speed. Difference between cruising at 65 and 75 mph is
a few mpg or more. Standard tire pressure of 30 psi. Anything more is
silly unless you have 3 fat people in the back seat. I think mileage
in the winter drops because it takes the engines of gas and diesels
that much longer to warm up. Only way to test that theory is on a dyno
with different fuels and a controlled load and temp. Well maybe not
the only but the most accurate.

I am getting 44 MPG on a 2003 Jetta TDI wagon. I have not increased the
tire
pressure as suggested to get higher MPG. I drive at 75-80 MPH on
highways;
slower in city. In the winter, MPG dropped to 39 with the winterized
fuel.
Still that is considerably better than my Chevy Tahoe, 13 to 18 MPG on
a
good day.

I have a 2003 GLS TDI too. I bought it last November and have averaged
about 40 MPG until last fill-up. That one was up to 45 MPG. Does that
mean they have switched to regular diesel?
