Small british engines were meant to be thrashed, change gear when the valves
bounce, don't lift when you shift - in the company car. In your own car
shift slightly earlier.
At 90 mph I might be at 6,800 in 3rd (close ratio box remember) or 5,300 in
4th and 4,500 in 5th - most likely I will be in 5th. High rpm does reduce
engine life - even with a synthetic eventually.
Most modern european cars have a rev limiter fitted so you put the pedal to
the metal and wait till the front end dives (limiter kicks in) and then
shift. The limiters are usually set at 6,800 or 7,000 or whatever. The
first time you do this (in a hire car) you think you have blown the engine
but it's just the limiter.

to 2200 rpm at 55 and when I am dong 60 at 3400 rpm. I think that is a
little high.
Are these engines designed as high reving engines. Is it considered normal
to run at say 4000 to 4500 rpm? My Drivers handbook does say to operate
between 2000 and 4500 rpm. It also says for short periods between 5500 to
6300 and that 6300 is the end of the safe operating range. The red sector is
the danger zone ( my red sector starts at 6500). There is also a note that
says to avoid hard pulls at low engine speeds as this will have detrimental
effects on the engine.
So by limiting my driving to say under 3000, am I doing detrimental effects
to my engine. The concept of running normally around 4000 is not foriegn to
me, but it is not normal for the vehicles I am used to driving.?
