Best Fuel Mileage ???
« on: February 27, 2007, 11:21:34 am »
There's an old guy, like myself, in BC who claims he's getting 100mpg from a turbodiesel Rabbit :roll: and is shooting for 120mpg.
What's the best you've accomplished?

Best = 47 mpg (summer only)
Worst = 32 mpg (winter city driving and winter 40+ mph head wind)
Average = 40

I have always found I get better mileage in the summer.  I am still not for sure why.

DC if you re-read his notes you'll find he has only actuallyattained 70mpg imp and is suggesting we may reach 100mpg; he only suggests 120 as a goal  :shock:
I have reached 62mpg imp in a 'Q' on a 250 mile run (60- 65mph + a bit of 70mph+)

Thatr's not what others on the site are saying and it definitely isn't what he's insinuating, but he is a wiley old cuss. He's hard to nail down. He insinuates he's got 100mpg and is going for 120.
Really, though, all that "hillbilly tuning" super-lean talk and all he got was 70mpg? I can do that on a good day with no tuning at all.

I'm inclined to agree he does flit like a butterfly :wink:  Apparently a world survey put the Scandinavians at the top of the happiness tree...
My goal is to attain 80mpg imp in a 'Q'

quatums do great mileage despite being heavier, the one guy i know has had quite a few of them and has nothing but but words for them.  i think a vnt 1.6 in a mk2 scirocco would make it easily possible to get into the 70mpg range.  the mk2 sciroccos are extremely aerodynamic.  i talked to a guy at h20 this summer that had an 8v scirocco that he is running on megasquirt, not even tuned properly, he gets 40mpg and thats with the 4k close ratio tranny that they came with.  insane.

I don't keep track of mileage in the winter, it's depressing. I recorded 4 tanks before winter and best was 44.6MPG

I want to get 1200 a tank consistently. That's my goal for the summer. I'll need to do a compression test first and see if my engine is up to it

Yes, that's with my 97 Jetta 1.9TD. Why?

Now mind you.....that's driving it conservatively (shifting at about 2500, staying at 100 km/h or 60mph on the highway etc). Harder driving (shifting over 3000 and doing 70mph on the highway) drops it to 50-52 mpg.
