Any idea? I'm trying to justify the purchase of a Jetta TDI to replace my
current 31 MPG non-diesel car. If you have numbers, please explain quickly
what type of driving (mostly highway, mostly city, etc).

Thanks,

Al

Depends on your driving and driving habits. I have averaged 45 city/highway
on my 99.5 new jetta tdi over 113k miles. When it was mostly highway it was
always 50 or better. Mostly city is about 44-46. If you beat the snot out of
it then expect around 40. All numbers are for standard trans and autos as
less.

I am not sure you can justify it just on fuel cost, but then if prices
keep going up and get anything close to what the rest of the world pays,
then it should. (I am speaking from a US perspective at this time)

26 + 6 = 1 It's Irish Math

Resale values are high. Good luck finding a good one at the right price, but
that plays in your favor on the sell side also.

I get around 6.2L per 100Kms (you figure that out... I dislike since I dont
have Miles or Gallons showing up on my car using MPG)... In the winter I get
around 6.5-7L per 100Kms... best I have done is 5.7L per 100Kms,

These are figures for a 99.5 Golf with the AUTO transmission... yah. not as
good as the manual especially in the city.

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?

Warmer weather helps, and your engine is breaking in and running easier, so
it will burn less fuel... My dad's new 2.0L Golf (with around 2500-3000K on
it now, since January) was burning 11L per 100Kms (city) and now its down to
around 9L per 100Km... it keeps getting lower as the engine keeps breaking
in.

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.

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. ;-)
