Heavy car £50 and need to do 700 miles can I?

Car speedos can't under-read, but can over-read up to 10%. Run of the mill cars tend to go as near to that limit as possible to both flatter their drivers and screw up accurate fuel consumption (using the odometer).

I know indicated speeds are overestimated, but are odometer (distance) readings really commonly wrong by the same amount too?

I don't regularly check, but one long journey I do quite regularly is 192 miles according to Google maps and 193 miles according to my cars trip computer (I noted numbers down to monitor fuel economy once). Although I guess I've never checked that the trip computer matches the main odometer...

Why on Earth would you buy an ST if you can't even afford to fuel it?

If you're having to do 700 miles and you absolutely cannot find more than £50, I don't think driving (at least in that car) is for you. The ST TDCI can throw some scary bills with zero warning.

You missed the bit where the OP's non-weird husband challenged her to power the car by magic instead of using fossil fuels. If you read the thread there's always a logical explanation.

Trucks tend to do what my car speedo indicates is about 60 mph but which my satnav tells me is more like 56-57 mph, is this possibly where the confusion arrises?

You're probably spot on there.

Trucks have a tachograph/speedo which needs to be accurately calibrated every couple of years.

The test centres check the date sticker on the tachograph as part of the annual test.

I use my sat-nav speed to set my cruise control and find that loads of folks slow down to 65mph to pass speed cameras on 70mph limit dual carriageways.

they should be limited to 56mph

Not according to https://www.gov.uk/speed-limits

Tescos, Morrsions and now sainsburys as well i think limit theirs to 40 on a single carriegeway...damn them! and 50 on other roads

See the link above. Max for >7.5 tonnes IS 40MPH

They are just enforcing the speed limits, not imposing arbitrary lower ones.

Aren't trucks limited to 56 mph (90 kph) due to some EU regulation though? Or possibly just due to a continental speed limit to which the limiter is set and not disabled on UK roads?

A lot on the continental trucks are certainly not limited, even if they should be.
Many a time I've been sat at 65+ (sat nav speedo) in the middle lane with the caravan on the back and had to pull over after passing other trucks in the inside lane, to then have a truck blast past a good 10-15 mph faster blowing me all over the road.

enough about lorries, eh?

Well, OP...your remark about possibly having to 'drive like an old person' is a bit off, considering you have grand-kids?

Trouble is, the 'old people' actually long since got the message, so maybe they are truly worth emulating?

You state you have 700 miles to cover?

And only £50 to spare? [plus, whatever is in the tank..so that may be 60 or 70 quid's worth overall?]

Further back you posted how your intended mileage was made up?

Why not [for the duration?] simply re-arrange the schedule for the grand-kids?

Or....why not get onto something like Google, and see how many [shorter] routes are recommended for your journey?

Why not, indeed, book a Travelodge/Premier Inn [my choice].. room nearby mid-week, make one journey down, stop over nearby, then return for the weekend with the kids?

Don't think of driving like an old person...simply think [and find out how to] driving economically?

Try driving using your eyes, instead of technology?

Shed the passion for speed..you cannot afford it.

For around home, why not a bicycle?

Of course you were breaking the speed limit as well if you were doing 65 mph whilst towing a caravan .

The OP's question was answered ages ago, they are long gone, and were highly likely trolling in the first place...

Im wondering if gaz is talking about continental trucks on mainland europe. Think speed limits for towing caravans may be higher over there.
