I've got a 1.6 tdi seat ibiza sport. I've recently had the egr valve and cooler changed. Don't no if that makes a difference. But I've just started doing a few miles for work about 50 miles a day. I'm currently getting up to 72 mpg or so the computer says. I'm getting around nearly 500 miles on a tank if I keep my speed down. Does anyone else drive a diesel and do a few miles for work and fishing. I done 370 miles last week and used just over half a tank.

How much fuel does it take to fill it ??? The mpg on the dash /trip computer can be wrong

I think he means litres rather than cash terms as different companies charge different.

That sounds like about a 40-45 litre tank. Bit of basic maths based on price per litre round here.

If you're getting that many miles out of it then fair play to you.

I noticed that keeping my revs below 3000 makes a big difference to consumption. Less aggressive braking and acceleration too. Basically being a better driver I suppose 😁

I'm looking at a Toyota ch-r hybrid for my next car. Would be interested to hear any knowledge on them. ..

I assume this is your model of Ibiza? Real worl MPG figs are there for you to see from actual owners and is a good guide of what to actually expect.

You can also check out all the other cars as well. Published figures are pretty much complete bull as you can see.

Some other decent real world MPG diesels.

And just to emphasize what bull manufacturers can claim..

Driving like that makes a.massive difference you are right Mal.
I teach people.to.drive. If somone is often going from accelerator to brake they aren't looking and planning ahead.

I'm always a bit dubious letting the computer work it out. I'm not sure how it calculates the figures but if it's checking the tank level and it's not accurate, it could be miles out. Best bet is top right up, reset the trip counter and then note the results when you top up again. Divide the litres by 4.54 to convert to gallons.

I've just bought a newish Nissan Quasqai (1.5 L diesel - don't get the petrol version) and it supposed to be good for about 60 mpg on a decent run. Compared to my old 2 L petrol car which probably topped 30 mpg, the power is low down and it's a superb drive.

Last car was 22mpg if I behaved myself, 17mpg if i was heavy footed, so glad I sold it last October and have gone electric.

The missus has a 1.2 fiat 500 and I'm sure the on board computer is giving a reading less mpg than what it's doing.
When you put it in instantaneous mode the reading fluctuates wildly even when you do a steady speed over long distances. I don't trust it.
Only way to know for sure is to fill to the brim, do some miles, fill up again and do the maths

For many yrs I had a volvo 940 se,redblock a lovely old estate ,very thirsty car..then I discovered smooth driving practises ,never over revving the engine ,and acceleration steadily ..then I got into hyper miles,or mile'ing, I use the roads ,inclines and gradients to my advantage..

I also make sure my tyres are all equal pressure and not soft..,I save a lot of money doing that...

Best tip I learnt ,was to not rev past past 2.5 rpm keep the gear changes ultra smooth..I can do this where I live, but it may be different to other busy areas..

It's a real skill,is hypering or coasteering,not the jumping off cliffs ,coasteering lol..

It works..

That's great until your engine begins to coke up. Driving too conservatively causes problems

It does work. I'm a driving instructor so poodle around town a lot. The occasional short 50mph dual. But mostly town traffic.

We teach economy when driving. As we are training to look ahead and plan and react early, also to be defensive on position and speed when you can't see. That makes economical driving but there's room for more.

See a brake light. Come off the accelerator.
Junction coming. Come off the accelerator
Narrow gap,.oncoming traffic. Come off the accelerator
At the top of a hill. Come off the accelerator.

You can always go back on it.

If you are regular going from accelerator to brake you aren't
Observing and planning well enough.

When I go for a beer I often get the bus. Jesus, those guys gun it up fast and slam on the brakes constantly.

Regular drivers approach their junctions, especially corners, way too fast. Last second they slow way down. Who are they trying to kid? What a waste of fuel.

I.like to think of it as if you were on a push bike would you be peddling hard or coasting? If it's coasting you shouldn't be on the accelerator.
Are you sure?

This action cannot be undone.

Yes, continue
