A used car dealer tells me that when dismantling car engines, he finds that a car engine with, say, 100,000 km on the clock is considerably more worn if the owner has driven mainly short trips, spread over a long time (e.g. . 5 years) or when he has always made long journeys (eg on a motorway) spread over a short period of time (eg 2 years). Is this claim correct? Why or why not?
Answer
hi peter,
studies have shown that 90% of engine wear occurs during “cold” running of the engine, because the oil has not yet reached the desired viscosity.
So it makes sense that a car that makes a lot of short trips wears out faster
