I own a 96 TDI and on the way back from NYNY to KCMO I got just above 44mpg doin 80mph. My brother and I are 'big boned' and we had a whole bunch crap with us so I think that contributed to the sub 50mpg. Besides inflating the tires and removing the snow screen what would be the best bang for buck eco mods?

Thanx,

Slow down! How can your expect to get good fuel economy driving 80 MPH?
Do about 60 MPH, and you will get closer to 50 MPG.

I am used to driving performance cars so it'll take a while for me to lay of the go pedal.

I interpret that last reply to imply that you don't really want economy tips.
OK, here's one that will still allow you to drive at that speed;
Don't use the brakes.
Any fuel used to accelerate and to generate momentum is squandered when it is turned into heat and brake dust. Once at speed, whatever it might be, you have turned fuel into momentum which is still useful to you. Braking and turning that momentum into heat and noise will not allow you further use of that energy.

I still drive a performance car, but I can get 90+ mpg in it when I concentrate on economy.

You can't get 50 MPG doing 80 MPH. In fact in my car I'm lucky to get 40 MPG at 80.

That said, slow down going uphill and speed up going down. Clean your snowscreen/airfilter, advance your timing, inflate your tires, throw out any unneeded weight, wash the car, use cetane-improving fuel additives, and I've read that single-digit percentages of biodiesel can return single-digit improvements in MPG due to improved lubricity.

Both of these benefits are achieved by using Schaeffer's Soy Shield. It is 50% biodiesel (from soybean oil, of course!) and 50% various additives.

I have never heard of anyone using Soy Shield and not liking it (well, except for chiefdiesel!!!). I never leave home without 10oz in my truck just in case I get fuel while I'm out!

How about fuel at $0.10/gallon?
Then you don't care what your mpg is.

3mpg increase is alot. Can you use redline for newer A4 manual trannies? Is it better than the factory fill? If there is such an increase in mpg's alot of people must be using this stuff. Can anybody chime in if you are using Redline MTF on a A4 and give your results?

Redline MTL is BUTTA! Used it for the first time in my Integra and WOW did the car feel different. Smooth shifts and I never had a problem finsing the gears. Be expected to pay about $10 a quart for this stuff, but it's well worth it.

I've not used redline in my Jetta but I along with most BMW motorcycles riders use it for the trans and driveshaft. The BMW dealer sell it in the store. That should speak of how good Redline is.

I'll probably get around to putting it into the Jetta, soon.
