My post was not aimed at you personaly, as you rightly say, you didn't mention freewheeling. But others do, so it was a general comment and not meant to be personal.
With reff to your post, 3 psi doesn't matter either way, my car is often that far out when I check it, but.. again others seem to go to what I consider, extremes, in order to save a few cents..
I agree entirely on most points you make, the only real diff seems to be, in my case I drive the Accord because it is a fairly large (by our standards) very comfortable saloon car, with lots of nice toys in it, and I like to drive it in, erm, shall we say a somewhat "spirited manner" just for fun. so it's MPG is not something I even think about..
One brief political comment I would like to make is.. Untill recently the UK gov banned using veg oil as a fuel for diesels here, on the basis that we were avoiding the UK tax on fuel.. But .. due to the global warming issues we are now having, they have been forced to remove that ban so we will soon be able to run cars here on veg oil legally. Common sense did prevail over profit making eventually.
so it's MPG is not something I even think about..
