Absolutely correct. My wife and I both often drive the same car, but I
always get better economy for a similar journey, and probably get there
quicker.
My 405 DT estate got 47 on long runs, 43 on local, but with very short runs
round town it could be much worse. they are not so economical when warming
up, like most engines. By long journey I am talking of only 100 miles or
more, cruising around 80. London to Stirling, 4 people plus luggage, 80 all
the way, 47 mpg.
Watch your right foot.
Just try an experiment. Accellerate fairly hard in a higher gear from about
2000 rpm. As you do it pull your foot off, and see how far you can lift it
before the accelleration reduces. That is the point you should aim for, as
more right foot is only putting more fuel into the engine than it needs,
resulting in smoke. The injector pump is quite a crude device really. Later
electronically controlled ones might be better.
