Although Summer petrol is denser than Winter petrol.

So the car doing 50MPG is more efficient than the car doing 18MPG. You simply say that is wrong, so you are saying that a car that can drive 18 miles on a gallon of fuel is more efficient than the car that can drive 50 miles on the same amount of fuel. This clearly demonstrates that you don't have any mathematical understanding. You offer no explanation for your sweeping statement and you have made yourself look silly!

No, I am saying there is not enough information to decide, because the amount of fuel in one gallon varies. This clearly demonstrates that you don't have any mathematical understanding. You offer no explanation for your sweeping statement and you have made yourself look silly!

Prove me wrong. Well they're not are they because CO2 is specifically measured as grams per kilometer so fuel weight or volume doesn't even come into it. Its prestty damn easy to find the respective figures for equivalent petrol and diesel vehicles and to see that diesel wins hands down the vast majority of the time so I'm not sure where that spurious quote came from but its quite clearly bollocks. Prove you wrong? Go look at this site then: http://www.carpages.co.uk/co2/ B2003 |
