1 gallon [US, liquid] = 3.785 411 784 liter
1 gallon [UK] = 4.546 09 liter = 1 imperial gallon


44 mpg (US) is 5.35 L/100km
Either engine in a Jetta should really be able to use less than 5L/100km (47 mpg US) with a manual transmission.
In summertime and long distance riding you should really be aiming for 4.5L/100km - or better.

And they can do better, so there's plenty of room for improvement.


Good website for all sorts of conversions, including fuel consumption :
Online Conversion - Fuel Consumption Conversion

The Quick Links on the right take you to all sorts of measurements and conversions.

euro... mpg # calculated with us gallon which is 3.78l, i think imperial is 4.18? also done on my regular 360km route averaging 100km/hr, has a lot of long 6-8% grades. on a different route i took last summer it seemed to do better.
thanks for the welcome guys

When I went 1-size-up from stock, I think it was a 1+ lb increase per tire (for a 2% gain). When I looked at 2-sizes-up-from-stock, it was a 3+ lb increase per tire (for a 4% gain). Because of that I only went 1-size-up-from-stock.

Depending on how you look at it, the extra lbs hurt you in acceleration but act as flywheels during coasting (right folks?!?!?).

i dont think the extra lbs would hurt me as i do vastly more highway. i want to try this stuff then go on to stuff like blocking lower grill openings as my car is td - no intercooler. Nothing to crazy...yet

I think you're probably right, but I want other people to keep the detail in mind. In retrospect I think I should have gone two-sizes-up from stock.
