1.9TDI Fuel Economy

Post by DCassey » Wed Oct 10, 2012 8:43 pm

I've done a bit of research and everything seems to be about power gains, with only a few nods to improved fuel economy. I was wondering if you could give me a slightly more definitive answer as I drive 250 miles between uni and home each weekend to play football (I know, crazy, but I worked hard to get where I am and don't want to leave!! :D ) so while increased power would be nice, the economy is important.

The reason I'd like to know is I want to try get an idea of how long it would take to pay for itself in saved fuel to see if it's worthwhile getting now or just keep the money in savings for Mongol Rally next year. I currently get a not too shabby 50-55mpg over the trip but improvements are always welcome ;)

Cheers,
DC

If you get 50-55 mpg already how much more were you expecting to get ?.
There are some big claims made for economy remaps and I weork for BT and saw an internal article the other day saying they are going to remap all the vans in the BT fleet and were expecting to save 25% in fuel bills.
Sounds like some senior manager has been reading too much sales blurb.
If you got an extra 25% on your car you would be getting 62.5- 69 mpg ?? instead of 50-55 mpg.
You can get improvements with economy maps but I wouldn't bet on any more than 10%.
Do you have a PD engine or an earlier VE pump engine ?. The earlier engines are the best for economy.
Fit some 195/65/15 wheels and tyres on and dont go above 60.
