Petrol consumption

[Norfolk Ollie]

I hit 41.7 mpg today, on A and B roads, driving like a snail with the kids in the car, then ended up with 39.9. after a 30 mile journey. Pretty pleased with that although the wife's average 8 mile round trip to the school only returns 27 ish. I'm thinking of getting a stage 1 done at R-tech soon so will be interested if this increases the MPG on an economy run but I can't see me being 'economical' very often!

Why is it not advisable? Please don't say something along the lines of 'it suck up all of the crap at the bottom of the tank' as that simply isn't true

See the link here http://www.dailymail.co.uk/news/article-3213671/Why-never-drive-quarter-tank-fuel-827-000-break-year-ignoring-warning-light.html .... this is petrol; not highly refined rocket fuel...stored in manky underground tanks in fuel stations, very often contaminated and then put into cars, many of which have done well over 100,000 miles, and as the article states, guages are very unreliable.....You risk it if you want to.....was only advice; not compulsary. If you know better, then please carry on.

40 years ago - yes it was an issue. Tanks would rust, water contamination would sit under the fuel etc. On a modern car, where the inside of the fuel tank will look like brand new - no.

Not to mention these cars already take their fuel from the bottom of the tank, have a strainer and a fuel filter designed to catch any 'sediment' or contaminant... Not to mention that if you did run out, the in-tank pump will prime the system for you with no need to 'bleed' it. I could go on and on.

Ok, I am 'old skool' and that was the thinking back then........

Daily Mail might not best the best 'pedigree' of motoring journalism, but some of it seems to make sense.......I hear what you say, but why would you want to run so low, and risk running out of fuel? A change in 'driving style' or traffic situation can alter the 'fuel remaining / distance figure' dramatically, so best not to be relied on, other than in an emergency situation....
