Don't get rid of it Jimmy!!! You'll regret it the same day! lol.

I have a bone stock 88 Jetta 1.6TD that me and my woman commute to work in 5 days a week. It is 100km on the dot round trip per day, and with other driving after or before work and on the weekends we usually total about 600-650km for the week. We get 40L of fuel a week from work and we can't run through it all for our weeks worth..

That puts us in the 5.5-6L/100Kms, and this is with cruising the highway at about 135-140km/h (83-86mph) for a good chunk of it both ways.. Our engine gets seems to get its best mileage right at 3200-3400RPM.

Don't give it away.  You will be kicking yourself as he says. 

Lost out on the 500 dollar darling. Seller decided to pull it back and spend the time rebuilding it himself this summer.  So close and no Cigar.

If it isn't in my drive on Saturday for 500 then what good is it to me?  Do not tell us you bought it for that.  We kill for less you know.

Reminds me of my first TD, was an 85.
I haven't driven one in years but I remember them
being a lot more like a car than a Rabbit/Caddy and less
like a go-cart.  The pass rear door took a fire hydrent into
itself about a foot whilst spinning @45mph or so.  Drove it
home after patching the water sep tank that broke on impact.

I saw someone mention that they get best mileage at 80+ mph. Not. You will get best mileage at ~40 to 45 mph. Above that and the air pressure begins to eat up power exponentially. I typically use 4.5-5L per 100km in my 90 TD -- regular freeway driving at ~60-65mph. (100-110kph) I can tweak it and get better mileage but I like to have power when needed so I split the difference. I keep all 4 tires at 44psi, but what I find affects mileage the most is my right foot.

The NA motors are much less effected by driving style as far as fuel mileage.
I always liked that, having to drive easy to get good MPG is annoying.
Course they are slow, but hey..

Agreed, except I think you meant affected?

Doesn't matter what you have under the hood. Increased speed = Lower mileage once you pass about 40-50mph. A bit more for low drag vehicles, VWs not included. But I couldn't care less whether you agree with physical reality or not, so go on believing whatever you like.

I hear you. I had it off the road for almost 3 years till Scott put the engine in. He also put in a ton of stuff like the new radiator, the Giles IP, and tons of stuff I cant even recall. And had a "guru" from TDIclub do even more work to it. As we all know, these cars are addictive. It is a blast to drive, and even with vinyl covers, the Recaros in there I got off the Vortex are more comfortable than the seats in my 09 TDI. I had the floorpan worked on, and would love to spiff it up. Like you, I do a ton of driving, and with the TT D/P, 2.25 exhaust, it still is slow. Scott had a TD with 180k he would have thrown in but I went with the rebuilt N/A with no regrets. I would love to drive this across Country in November and know it will make it. Still needs a few minor things, and a weekend trip to Canada and a visit to Tyler is in the plans to get them working. This car is like an old pair of shoes or a favorite t shirt, you wanna throw it away but you just can't..........

Stay safe,stay well. Jimmy.

Please define slow. Have you timed it? My 92 Jetta with gov mod beat out a 1999 TDI on 1/4 mile pull on a dyno. You're in Suffolk I'm in Queens. We should get together sometime and compare our cars.

Volumetric efficiency.  Check it out.  You aren't exactly wrong but there is more to it than that.
Forced induction motors are somewhat of a different animal as well. There's some really good
data out there if you go hunt it up.
