Terribly boring mpg question... - Rob the Bus {P}
Not too sure whether this should be here, or in Technical. I'm sure the powers that be will move it if need be ;-)

Anyway, I am driving from the South East to the North West and back this weekend, a round trip of about 520 miles, with about 50 miles of faffing about up there. The car I'll be driving is a 1992 Astra 1.7D (yes, *that* Astra...) and I generally never go above 65 ish - I certainly don't scream down the motorway like a loon.

Does anybody out there know roughly how much this trip will cost me diesel-wise please? I'm terrible with figures (you should see mine!) so any help would be much appreciated.

Thanks all

Will try and put my maths abilities to the test here :o)

We'll take it the car is doing 45mpg which chances are it's prob doing a bit better but better to be conservative...

So...570 miles divided by 45mpg = 12.67 gallons used

There are 4.546 litres in a (imperial) gallon and so the cost of a gallon is roughly...

4.546 multiplied by 0.77pence per litre = £3.50/gallon

Therefore multiply the two...

12.67 gallons x £3.50 and you get £44.35 so budget 50 for the safe side!

Though I would say, I bet you'd do it with 40 quid's worth of diesel but better to play safe...

Now if you can get some nice red dyed farm diesel that's a different matter :o)

Assuming 40mpg and £3.40 per gallon (74.9p per litre)...you'll not get much change out of £50

I can get 40mpg out of my petrol Vectra if I wear cotton wool on my feet (so usually 30!) - hopefully Rob's 1.7D Astra should be doing maybe even in excess of 50, was just "playing safe" with figures as regards 45 to the gall...

This is all very well but how much would it cost him in vegatable oil? ;)

That Astra is so famous now you could probably get the trip sponsered by HJ himself!

A few years ago my newish (1991!) Astra 1.7D (original Vaux engine - not turbo) only achieved low 40's mpg not much better than the Astra 1.3L petrol that preceeded it (39 mpg)

Well, thanks for your help guys.

I've been and come back now and used about £35 of diesel and done just over 600 miles. That doesn't sound too bad to me!

About 58 miles per gallon. I can get 58 mpg out of my Passat but only if I talk to it really nicely.

Value my car
