MPG for diesels

Post by brookie »

Hi Weazel
45-50 on your diesel sounds good. You've got me worried now. What type you got? 1.6, 1.6TD or 1.9TD? I run a 1.9TD AAZ and that gives me 33ish which I was quite chuffed at! Should I be looking for more?

its a 1.9 non turbo, with 225/70/15s on the rear and we did the gathering off the hill on £20, thats a 200 mile round trip. ok only 15 miles of that was off motorway driving, but to my reckoning thats 50mpg!! is it not?
by the way i stay in eco mode = 56-60mph.

Depends on £/litre I'd say, and whether it used exactly £20 worth or a pint more or a pint less..

43.4 mpg @ 95p/litre

42.3 mpg @ 93p/litre

40.9 mpg @ 90p /litre

39.9 mpg if you used a pint more than the £20 worth at 90p/litre

you`ve got me inquisitive now, i think the next long motorway run we do(woolacombe in the summer) i will carry out a test in £10 increments to find out exactly, as it would be interesting, and it would also keep me out of the pubs!!

How do you plan to measure the £10 increments?

Wouldn't it be better to brim it before leaving, write down the mileage (ignore the litres), drive down there, brim again and note the mileage and litres before returning, brim it again upon returning, noting the mileage and litres? That'll do for starters...

then, having started that running record, keep it going for say another 5 or ten succesive fillups to produce a solid record for a 1.9 NA for us :)

It only takes a re-brim at one fillup to produce a line in the sand that can give you mpg-to-date, so not all fillups have to be brimmed, but you have to record all the others of course (litres not mileage).

You never know, with 15" tyres, if you also calibrate your odometer with a GPS (over say 100 motorway miles) , you might be doing more mpg than you think :wink:

But unless the empirical record is solid, you'll never know.

P.S. Don't use the trip, if you have one, use the odometer mileage...

You want to try my Aircooled auto Westy-sometimes it hits 12mpg!
And it's a poptop.

i know for a fact my satnav is 1-2mph out, ive used it in about 30 different hgv wagons and my t25 speedo is kmh, so thats not %100. i cant remember how much derv cost at the time but we did woolacombe a few times last year 400 round trip and all i put in the tank was £40. i will mark out 2 different junctions (say j1 to j25 m5) , take what multimap says is the distance between em and use my satnav aswell to come up with an accurate measurement. brimming it sounds good.

Would be interesting to see on distance travelled on a known calibrated route like that - that's fairly straight - they really shouldn't be out too much. Anybody know what the clock-rate is, how often they're reading position - and they should be splining any curves.

Was surpised to find out our Tom Tom doesn't seem to read-ahead based on speed and time to tell you a distance to go approachinga junction - way out! That's fairly simple stuff, unless I'm mistaken.
