Summer I got 39-43mpg, as soon as winter hit I was down to 33-35mpg.
Then I messed with my timing and got up to 38, THEN I noticed when I took a 100mile trip my odo showed 90 miles. So if that stays consistent I actually get more like 40-43mpg in winter. So in other words I'm not totaly sure what I'm getting. :roll:

'82 Rabbit, I put on a euro vnt-15, 2.25" DP, 2.5" exhaust, the result.....it whistled.

I removed the turbo, made a toilet bowl 2.5" DP, the result....it was deafening. Now it has a homemade muffler up front and a thrush in the rear, the result.....less loud.

don't really know what my milleage summer/winter is but what I do know is that my engine runs a lot smoother in winter. Something to do with cold/denser air getting into the diesel mix  :lol:  like having an intercooler without the radiator ...
