Thread: Ute upgrade

Exactly, my '13 PX2 manual is returning 8.1L/100 currently, the more modern versions are returning 13.5L/100 in similar roles but with more towing. I remain unsure how burning almost 5.5L/100Km more due to what is explained as emissions controls is better for the environment, when the percentage of each type of gas in the tailpipe is largely unchanged between the models?

Surely someone can explain this to me as I can't get me head around it at all...
