New Ibiza TDI MPG!!

[evoy2k2]

Hey people, its been a long time in posting or even visiting the site but now im back and have a new 12plate Ibiza 1.2 TDI......Love the car, nice drive etc.....

I have a small question, the estimated MPG was around 70-80mpg but after my 1st £20 worth of diesel ive done 140miles.....i expected more than that and i done drive crazy! My car doesn't have a trip computer which suprised me, on the other hand will the MPG get better once the car has worn in n done more miles etc and is there a way i can work out MPG?....Any help would be appreciated,

Thanks

Doesn't have a trip computer? are you sure?
140miles from £20 is about 45ish MPG isn't it?

just brim the tank next fill up - reset trip - next brim see how many miles covered to litres - input into site below - easy peesy.

don't expect to get much better than 60 mpg unless you do long haul trips & drive very steady.
I have had mine for 16 months covered 14k+ & still have a job to get over 60mpg done it twice 63mpg was the best.
hope you can achieve better like some owners do here.

Cheers for replies guys.

No it doesn't have trip computer, you usually have a switch on the wiper switch but hasn't got one, im very suprised as i though all cars had a trip computer!

Ive just put £20 in and reset the counter so i'll report back on how many miles ive done....

I have the same car as you. But my is the Ecomotive edition, I wonder if yours is too? Here in Greece, there are only the ecomotive and non ecomotive and both are REFERENCE edition: A/C, metal wheels with covers(yikes!), no OBC, mine is 5D and the back seat fold as a whole(100%, NOT 40:60, !#$#$#%#).

So face I have clocked till today, since last June when I bought it, around 18300km. Done the first oil change at 15,000km. With no OBC, but with my mileage, I can say mine is doing around 5.3l/100km, there is a the average combined consumption. However, I really ramped it! That's why I chose this model, reason for economy. Power delivery is ok not awesome at the 1.2TSI. Can't get best of both world, isn't it?

60+ is very good! I hardly can achieve that even though driving fuel cautiously! But is your 60+ on highway or combined fuel consumption?

My 1.6 tdi cr is returning an average overall of 57 mpg over 16300 miles.

Nah, mines not ecomotive,just a 1.2 TDI s a/c.....Ive had the car around 4days but thought once ive done some miles and car has worn in properly maybe the MPG would be better..........or shall i just take it down motorway ??

 

[DJ_Steve]

ive had 62.3 out of my 1.6tdi last week but it was at like 2am in morning driving at like a constant 50mph

 

[evoy2k2]

Ive taken it down motorway after i finished work this morning, hopefully MPG has improved

I still cant believe it hasnt got trip computer :-(

I've been told that these CR engines really need to be driven fairly hard for the first 5-10k to get them loose. I've also been told they need to be driven at higher revs than a conventional diesel, otherwise your DPF is gonna get clogged, and when you do get on the motorway, your mpg will suffer due to regeneration.

So I've been advised at first, drive it a bit harder until it's broken in, then drive how you want at slightly higher revs compared to a normal diesel, but at least once a week give it a good run for 10 minutes at over 3.5k rpm to keep the DPF clear.

It sounded counter productive for the MPG for me too, but in the long run it's supposed to help improve it.

I've been driving in the range of 1,500rpm to 2,400rpm, then switching gear, and I'm still noticing some runs on the motorway are really poor on mpg because of a DPF regen. On the journeys where I haven't had a DPF regen, I've stuck it at 60mph and had 67mpg average, and a 70mpg average.

So, when the DPF isn't playing up, it does have the economy, you just have to clear it out every now and then.

Firstly I'm assuming you have read the info HERE?

Secondly, even if the DPF is on a regen, running on the motorway at 70 in 5th isn't going to reduce your mpg massively. At this speed you'll only be running at 2.2-2.4k rpm which is ideal for a regen. Running at 3.5k will hit your mpg, at 80 in 6th you'll only be around 2k rpm, I dread to think what speed your doing

How are you aware it's doing a regen on a run? Unless the light comes on (which it shouldn't) the only way to tell is by the tickover revs.

I would tend to disagree, to my way of thinking if you keep the rev's low it will be better for the DPF. The higher you rev a diesel the more black smoke it produces, so clogging up the DPF quicker.

 

[garybuttle]

according to the handbook it will regen the dpf naturally @2000rpm if held for approx 15 mins, in my 1.6 tdi this equates to 70mph in top for 15 mins, as for reving it , the comp om mine tells you to change up , and when you do the revs drop to 1100, do not know about the 1.2 but the 1.6 has so much low down torque that it does not need to rev unless you are in one big hurry.
Have done 16500 miles in my 1.6 and have never experienced a forced regen.

I've been told by an engine tech, and there are many articles relating to this, is that low rev city driving causes the DPF to clog up. All the people who've had to replace their DPFs are people who do town driving only and never get on the motorway. It's a HIGH LOAD/low revs which causes the DPF to clog up.

@Garybuttle - I have the ecomotive engine, don't know if it's different to yours, but I've only had the car 3 weeks and have had 1 DPF regen when I was running at low revs (i.e shifting at 2000rpm, and starting the new gear around 1200rpm). I have been driving on the motorway at 60mph ALL the time though so this won't have helped either. If you've been driving at 70mph, that's why you won't be having any DPF issues.

In my experience, the 1.2 TDI is not much more economical than the 1.6 TDI.

I have done two exactly the same journeys in both 1.2 & 1.6 TDIs, I stuck to about 70 mph and accelerated at similar rates.

1.6 TDI returned about 50 mpg
1.2 TDI returned about 53 mpg

I shall bow to your superior knowledge, after all you have had the car three weeks so from all that experience you will know it inside out and have sussed out all the DPF pitfalls.
I've only had mine for two years and done 32,000 miles and never yet had a DPF light on, but what would I know

I'm with you biker, had my car the same length of time and 31,000 miles and the only time I saw the DPF light was when i was driving like a granny to see how high I could get the MPG. Needless to say I scrapped that style of driving pretty quickly!

 

[gaffer1986]

My car is also two years old with 30,000 miles and I have never seen the DPF light.

****in hell mate, I was only saying what I'd been told.

So you agree with me markmeus, as I was the one who said low rev driving was bad, not biker.
