I recently bought a new car and have put around 800KM so far on it. The manufacturer recommends that I "break in" the car's engine properly by driving gently for the first 1000 to 1200KM.
I have been doing just that, driving it very gently and making sure not to go over 2500rpm, but last night, I parked the car and kept it on idle for around 2.5 hours with the AC running inside.
I guess my question is whether I did any damage or "disrupted" the break in process since the piston rings may have not been "seated properly" yet during the first 800KM that I have done so far on the car.
FYI - I have to take the car for its first service and check up when it hits 1000KM as part of the "new vehicle" check up.. I guess they will be changing some fluids there.
Thank you.
