when you buy a used car, the first thing you should do (besides getting a trusted mechanice to look things over for you before you buy) is to change all the fluids and ideally all the hoses and fittings... this should improve the efficiency of the engine... and should lengthen the lifespan of the car...Originally posted by viggen:
A friend of mine is buying a new car that has been sitting idle on the dealer's lot since March. Her dad told her that she should get the oil, coolant, and transmission fluids replaced because they have probably gone stale due to the fact that the car hasn't been driven in such a long time. Is he right about this?
