miles per tank

hi again
I was wondering what mileage i should be getting out of my 1.8 clipper auto at the moment i get around 300 miles out of a tank but that seems a bit low is there anyway of improving this.  i've already changed the carb to a webber 34/36 and that has got the car working better before that i'd never got to fill it up as it always broke down, now the only problem i have is it makes a loud clicking noise when the rev's are over 2k i thought it was the tappets as i had a ford that sounded the same but that did it all the time.  anyway this car wouldn't be fun if it didn't have problems
 

Seems pretty good to me. What you really need to do is reset your trip when you fill up, drive around, fill up again. Note the miles when you fill up and the number of litres required to fill up. Convert litres to gallons and calculate miles per gallon. If you are getting over 30mpg then you are doing ok I think.

I get low 30s on a long run and mid to late 20s in town. Needs a good tune up though. Generally not get more than 275 miles to a tank though…

hang on let me get this right…………….. you are upset with getting 300 miles out of a tank?????

 i only get 150 - 180 max!
 i know my engines quite heavily modified though, but i would be more than over the moon with 300!

Here you go Daisy:

Just run my 1985 1.8 GTi Cab over 342 miles at an average speed of 52 mph. This trip used 39 litres of fuel:

Conversion: 4.54609 litres per gallon: thus 39 litres = 8.58 gallons.

342/8.58 = 39.86 miles/gallon

Converting to kilometres/litre:

39.86 * 0.35401 (conversion factor) = 14.11 kilometres / litre.

thanks for the tips but it not really a problem now as my head gasket has gone these bloody cars

Here you go Daisy - latest consumption figures

Just covered 375 miles - mixture of urban, motorway A and B roads - about
25% urban
25% motorway
25% A roads
25% B roads

used exactly 50 litres of fuel (had to squeeze the last 1/2 litre in)

gives 34 mpg - so you should get around 370 - 380 miles to a tank on the above useage - will fall on an all uban cycle though

i managed to squeeze 210 miles out of a tank when i  was on my way down to dover for our germany trip last year and oo my god it was boring.

im of to newquey end of may and am wondering if i would get there on a tank? i can get about 300ish miles out of a tank on normal usage thats just around town no motorways so i think i should be able to do it? anyone else done it? to newquey from leicester its about a 5hour drive 350ish miles prob a bit more.
