I was wondering if cars such as the Peugeot 308 Turbo, Ford
Mondeo Ecoboost and Ford S-max, together with some Volvos with
turbo, all of which claims giving more mileage/power with less
fuel consumption, last as long as the normal (family) cars
without turbo ?
Will the turbo cars driven in a hot tropical country like
Malaysia, break down more often (given that turbo cars produce
more heat) compared to turbo cars used in cooler temperate
countries ? Have the manufacturer tweaked the turbo cars sold in
tropical countries in order for it to withstand the more severe
1. It used to be assumed that just because an engine was
turbocharged it would wear out faster and also because the
stresses were higher things would break fast. This is not the
case as engineering has progressed such that there are better
materials now which have better wear properties.
Lubricants have also improved to such an extent that even
with the additional stresses, lubrication is not affected.
In fact cars with turbos are actually running more
efficiently as a higher percentage of the fuel in the fuel
mixture is burnt for energy.
2. Despite the ambient temperature, the operating temperature
of the engine is the same whether in the tropics or in a
temperate country. The main difference is in that in a temperate
country it may take longer to get to the operating temperature.
Of course in the tropics there are small tweaks such as
tropicalised cooling systems with larger radiators and
differently calibrated thermostats, but the engine still
operates at the same temperature. therefore i would say that
there is no difference in the wear rates of the components.
