mg zt cdti range on full tank

[abs]

to any owners of the mg zt cdti, what sort of mileage are you getting on a full tank. i am getting around 400 miles which is mainly a mix of city and motorway driving (motorway is normally 25 miles a day). the combined mpg is supposed to be 48 mpg which if my calculations are correct should equate to about 697 miles on a full tank of 65 litres ( 14.3 gallons). my car has covered just over 1700 miles since new and i was hoping i would get over 600 miles on a tank of fuel. of course i understand it all depends on driving conditions etc will i expect to get better performance over longer journeys on motorway trips, will i get better economy once the engine has gained a few thousand miles?

it would be interesting to hear from others.

let me break your duck of replies. Don't seem to be so many ZT CD owners around this site !

I have clocked up 2000 miles now, with the following results.

On a great run from Edinburgh to Guildford at motorway speeds (!) I clocked 440 miles and filled the tank up with 56 litres. Most of my other driving has been round town and short motor way runs (to local dealer to ask about badge colours etc) and I seem to get 400 miles to a tank.

I am not sure how much MG Rover leaves us of the 65 litre capacity before all the 'empty' indicators come alive but I believe a running tank full is around 56 to 58 litres unless you are pushing it. This might help your mpg figure.

My figures should be worse than yours, with the auto box, but on the motorway run, the impact is less. Overall, my computer indicates around 32 mpg overall and on really short runs in cold weather I am closer to 30 mpg. The only other figure I was quoted was the dealer who was driving a 135 manual ZT-T and took it to France. Reckoned he got 40 mpg on the motorways.

I drove my (petrol) Rover 75 conservatively because thats how you drive them but with this new MG, its never long before the slider is pushed over to S for the pleasure of driving it that way. Thats why I bought it of course!

I reguarly take reports from customers of 47MPG on their CDT's

[subman]

I have unfortunately managed to run the tanks of CDT saloon and tourer dry and can vouch for the fact that the tank holds no more than 64litres.

Out of a total of 103000miles in the two motors, the first (saloon) averaged 47.3mpg. The second is averaging 47.1.

I bank on being able to get 630 miles out of a tank without trying too hard, but as experience shows I get it wrong occasionally!

In theory the 135cdti should be no worse but then with the extra power and torque you'd be silly not to get your money's worth!

Surprising thing is that the first set of front tyres on the saloon lasted 30k, whilst I'll be lucky to get 20k out of the tourer's.

47mpg ! Lucky old you.

My R75 2.0V6 can only manage 330 miles from a full tank (almost dry).

The handbook states the tank is 66 lites (14.5 gallons) which means that my 75 isn't only returning 22.75mpg :cus:

Oh well, I can't have everything.

How "almost"... do you measure the amount of fuel you actually put in to fill it up? Generally tanks have 5 litre + in reserve...

[MikeBRG]

I recently ran the tank low to see the refill volume and estimate the hidden reserve. With the range computer saying zero miles (engine warm and cruising) I refilled at 60.0 litres, confirming what cosb6 is saying. Its not good for the passengers' stress levels to do this - they tend to shout a lot !

To confirm my earlier post, I had 418 miles on the trip computer, giving 32 mpg but with round town stuff in mostly freezing conditions. Suggests things are not going to change dramatically until things warm up a bit.

I have convinced myself that if I drove for long periods at 70 mph on a motorway I would get 40 mpg but I do find it difficult to maintain this speed.

It would seem from our limited sample that R75 CDt drivers are doing a bit better. Would be good to hear from the new generation R75 131 CDT owners on this topic.

I ran a R75 2l V6 auto saloon for 64,000 miles and managed between 360 and 380 miles a working tank full on the average, with very little variation, mainly on the M25 in the rush hour (that is stop-go at 30 mph !). These are true average figures based on detailed fuel/mileage records. Driving this car was a real pleasure - the grandad effect - don't knock it ! Driving the ZT is pleasure and fun.

Curiously, on tyre wear, the rears went long before the fronts on my car and a colleague's. Unusual for a front wheel drive.

Just to broaden the debate, I notice in the Top Gear magazine long term review of a 190 ZT-T that a figure of 22 mpg is being reported for long term use. That is what I am comparing my figures against !! They probably are having even more fun than I am, though !!

I had a R75 Diesel (unchipped) which i got 38 mpg out of. Changed for a ZT chipped diesel and I get 42 mpg which is not surprising cos you don't have to push it so much due to the extra torque.

[MikeBRG]

More input, this time from a very favourable and thorough review of a manual ZT-T + 135CDTi , in the March 2003 edition of MG Enthusiast Magazine.

The author quotes a figure of 35.7 mpg after a week of varied but testing driving. He believes the Euro test figures are unlikely to be achieved in real life.
