Re: Best way to run in new engine?
I read somewhere you should run in the car in the same way you will drive it in the future.
If you run it in gently, the parts in the engine will grind to smaller tolerances. As a result, the car will have higher top speed (marginally), slower acceleration, lower oil consumption, the engine will not be so "wild" and will not rev so easily but it should last longer.
If you trash it from new, the parts in the engine will wear more from the beginning and have larger tolerances. As a result, the car will have better acceleration, lower top speed, higher oil consumption, it will rev very easily and the engine will be very ďlivelyĒ.
Anyway, it seems not a good idea to start trashing a car that has been driven gently since new for very long time, and you canít get the above mentioned pluses from car trashed from beginning.
Thatís what I read.
I think its good advice to treat the car from beginning in the same way as you plan in the future but I would still avoid redline for the first 2000 miles.
For the first 200-300 miles, donít forget that not only the engine, but tires and breaks have to run in. Donít do a lot of hard braking with new discs and pads. I agree with symonh2000, if any part has some hidden build fault or quality issue, it would most probably fail in the first few thousand miles. So donít push the car to the limit.
