hello all,

ive noticed my miles per gallon reducing significantly recently.

I can normally for 8.5 litres of unleaded get upto 50 miles.

i put this in on Monday and have since done 15-20 miles and have lost half of what i put in.

to me this seems like a lot of fuel - does colder temperatures play a factor in fuel consumption?

where are the hot spots for fuel leaks as i have read the lines can be quite brittle?

many thanks
ryan
