Gotta love Tdi economy

[Cam]

I did a trip from Nowra to Wollongong and back on the weekend and I averaged 5.2L/100km


It was mainly 6th gear driving, but a lot of hills and I was having a bit of fun in between. I love diesel, I think I'd find it extremely hard to go back to petrol after getting this sort of economy.

Around town I can get 700km out of a tank and thats in stop/start traffic!
Using BP diesel.

gldgti,

That's about 111km if the gearing suggested in Wheels a couple years ago is correct (53.1 km per 1,000km)


Neil.

haha, i reckon similar with most cars. thats about how far my car is out too (worked out from the odo-check zones on the major highways)

[Gigitt]

we just did a trip to Wagga Wagga and back via Sydney from Gosford in my mk3 TD. Achieved 5.14l/100km! 2 up with luggage and sound gear for my sisters 21st party. oh yeah, used the air conditioning for 90% of the trip (darned black car)
woot!

what is your tyre sze are you unning?

The reason I ask...

I just bought new tyres for my Mk3 TDI 2 months go...
I changed from running 195/50/15 to 195/55/15.
I decided this by using the online tyre calulator to match the original 14in tyres stamped on the car delivery sticker.

The 50 series tyres were runing 9% low on the speedo when compared to GPS.
Now with the 55 series tyres I amrunning 100 % spot on at 40/50/60/80/100/110 km compared with the GPS.

i run 195/45 R16

I flog my car senseless everywhere I go and I dont get higher than 6l/100km WOHOOOO

Had a small trip yesterday,
Barnawartha - Wodonga - Wagga Wagga and return
4.9

Also looking at my trip meter (I reset every fill) seeing about 750kms on it and still having a 1/4 of a tank left.

Overall average on the trip computer (#2) is 5.5

Dropping the speed from 110 back to 100 is a big help on the economy side.

That's good for Jetta TDI. How many km's have you done from new?
Also check it against the fuel docket, so you'll get idea how accurate is your trip computer.
Good results anyway.

Yes it is a MY09 common rail DSG. Had since new, done 43,000 k's now

I'll write the trip meter on the next docket and do a manual calculation.

Oh, my dad is also buying a Jetta 103 TDI now (MY10), probably a little to do with my influence. It is rated to have slightly better economy, will wait and see how long it takes for him to do better than me.

The best I have done has been 920km before the fuel warning light came on. On the highway at 115km/h indicated, aircon, 3 passengers and a full boot, I managed 5.7l/100km on trip computer. The best with a lighter load was 5.4l/100km.

Around town, in stop/start traffic, not uncommon to get at least 600km out of the tank before the fuel light comes on.

At current diesel prices (118 cents) it makes for some very economical transport.

This level of economy and performance of the TDI? Power WITH glory!

[Buller_Scott]

after many many trips to buller where fuel economy and torque are two key things to appreciate, im never going back to petrol. never.

i've put 45,000kms on my clock in just on a year and a half. i dont think i could handle going back to petrol and tiring the engine out after only 3/4 years.......

In the Polo according to the trip computer upto Maryborough from Brisbane I was averaging 4.1l/100km. Most I have ever had from a tank though was 910km although I do have a bit of a led foot.

...averaging 4.1l/100km. Most I have ever had from a tank though was 910km...

Do the ventectomy mod and you will get >1200km at that consumption.

See http://www.vwwatercooled.org.au/newf...8&postcount=18
and

(Or you can just use the expansion tank vent button manually.)

the venectomy is a fantastic mod you can squeeze a wee bit more than an extra 15L into your tank!

VERY HANDY!

Ventectomy?

I tried looking at the links but any images are not there. Anyone explain what the process is?

I haven't been game to run past 0km remaining on the computer. Never got more than 53L in so far. Anyone know how much the tank+expansion chamber actually holds? (how much further one could go in an emergency before running dry. I did run my first petrol car bone dry (carried a spare fuel can) to establish actual capacity. I understand it is not so good to run diesels dry but I thought I read somewhere that VW diesels have self-priming pumps.

Many moons ago getting a Greyhound bus from Brisbane to Melbourne, we got to Tugun and ran out of diesel 50yards over the road from the Shell station. (Someone forgot to fill up.) But we had to wait 3 hours for a mechanic to come to prime the injectors.
