Fuel Tank Capacity

[Billy Smalls]

I am trying to work out my mpg (foolishly, as it will only depress me)

I managed to get 43 litres inot mine this morning. I read somewhere that it's 46 capacity but then just read another set of specifications and it said 58 litres.

It's a May 1970 model...

Thanks

Hi,

Now that you have brimmed the tank full, the easiest way is to make a note of your mileage (or zero your trip meter), use up almost all of that fuel, refill the tank to the top again and make a note of how many litres you've added from the forecourt pump and how many miles you've covered since the original fill-up.

Divide the litres figure by 4.546 which will give you an exact conversion to imperial gallons. Now take your miles covered figure and divide it by the gallons you've used and this will give you a very accurate MPG figure.

Hi - thanks. I should have mentioned that the fuel gauge dies after 50 miles in from a full tank. I've run out of fuel a few times and whilst that is very annoying, my fuel filter is still clean, so a good sign the tank isn't rotten.

I trip the odometer every time - and bank on 200 miles between fills....

Billy, apologies if I'm teaching my Granny to suck eggs, but 'cassell's' method works well if you fill up brim to brim each time, note the quantity of fuel dispensed and the mileage covered. Your 200 mile range is conservative; I used to get 250 to 300 miles per tank back in the day.

46 L (c10 gallons) strikes me as being on the small side. 58 L (c13 gallons) seems nearer the mark, but maybe different models / years had different tanks?

With a dodgy gauge, it's always worthwhile carrying a can in the boot - I've been able to help several people over the years with mine.

Regards, John.

PS I've just had a look in my Haynes manual for the model, but - oddly - it doesn't quote capacities - sorry! J.
