exactly my point^^ I get 34 mpg from my Lexus ls400 on a good run ( not bad for a petrol engine ) 4.0 32valve v8, the engine is hardly labouring at 140mph but when I do those speeds the mpg is like 5mpg,

I never part with my cars not even the xk120I was drunk hick

edit: I always get a scale model of my favorite cars and much easier to keep up with maintenance
