Driving is a situation thing, so it depend on where and what your doing, I wouldn't dream of trying to go up hill at 35 in 5th with the pedal pressed, How ever driving on flat or down hill foot on the pedal like it had drawing pins on it and I was in bare feet that's a different matter. I work in a garage (not as a mechanic though) so I do understand about the labouring of engine's and I dont do it.
Filling up and all that weight, best sell my caravan then. lol
Oh ye and I run on over recommended tyre pressure about 30 to 31 psi
