20l is half full lol its and astra!

but ye sorry for opening a whole kettle of fish on this topic at the end of the day i only put 20l in because why always have half a tank spare? why leave a spare 20l of fuel when in the uk i pay £1.30 a litre for diesel doesnt make sense to me plus im in the uk im not going to freeze to death in a ditch overnight im more likely to crash and burn from all the fuel i got on board lol plus as for crap at the bottom of the tank i service mine every 2-3k and theres nothing in the fuel filter to worry about sometimes wonder why i even replace it

either way fuelly's calculator isnt goin to work for my type of driving/lifestyle but thanks for all your help anyway guys/gals and god bless

sorry 26l is a full tank :D

sorry 26l is 1/2 tank :D

how do i edit posts

If you service every 2-3k miles and change the fuel filter each time you're either throwing money away or running on used cooking oil! There should be no need to change it that often.
