MPG - what do they do ?

[toastie]

the 33 for a start ?

i would think there fairly good but awaiting a shock

With Betty (our white 33) long-term average is just under 34mpg over about 25k miles, most of that on fairly short local runs. On a good run out she generally gets around 42 at foot-down 70mph cruising, or 38-ish when she's towing. On a "sensible" run sticking around 55mph she'll manage high 40s

'Tilly the 32 (basically the same but 2 HP less) averages about 38 and will almost push 50 on a run.

Don't be fooled Toastie, SuperJoe gets super economy. ;D Gavina my 33 returns about 30mpg but I do 'drive it like I stole it' which is the only way really...

It is kind of hard to drive a DAF without seeming like you have something to prove. Simply because they are such fun, and as when you are driving one they seem about as wide as a pushbike you find yourself steaming through gaps other cars wouldn't even contemplate.

Certainly on a good run on A-roads they do very nicely indeed.

Kept accurate records of my MPG while I had "Pooh" (R.I.P.) and regularly obtained 35+ mpg, with 38 on one occasion ( and I don't hang about...)

As an aside, would anyone care a comment on whether it's better to floor the throttle to get to the desired speed & THEN ease off the gas or caress the throttle and get the belts & vacuum bring the car slowly up to speed? As I drive to & from work at anti-social times (4:30 am sometimes) I can afford to play with my driving technique without holding anyone up. I found it fascinating to see how my 33 could be made to move off slowly (and very smoothly) and would speed up to 30-40 mph without moving depressing the pedal any further. The car would slow on hills but on a level road the car stayed in overdrive and was VERY smooth & quiet.

Reading this is making my medical condition (dakadafitus) cause me distress.....

Not exactly a precise guide. A good excuse to post it nevertheless. Here's the Parker's Price Guide, guide from June 1983. (One of my earliest copies):


Whatever happened to 3* Petrol?

Just reviving an old thread regarding a Daf 33's M.P.G. I've spent quite some time tinkering with my 33; setting the timing & checking the tuning, and adjusting the point at which the vacuum cuts in to assist with the change-up action, in an effort to improve both the economy and the engine's performance in general. I've set the CO mixture to 4%, the tick-over to 900 RPM and the vacuum cut in at 2850 RPM. The car now feels much better and smoother and has just returned over 37 M.P.G. This included the run back from the Princethorpe get-together along the M45 and the M1 and another run from Barnet to Leighton Buzzard and back, as well as quite a bit of urban running around.

Not only has the economy improved, but the car now covers over 250 miles between fill-ups, thus making it a far more useable vehicle. I reckon this of us using their Dafs on a regular basis would be well advised to check these things regularly-the results will more than worth it!

Over the DAF years I've always found 33/37mpgsversge from daf33.but depends greatly on area you live ie hills or flat lands.
