Today i couldn't resist myself and i hit the gas hard a couple of times on my brand new abarth reaching 4000 rpm and then changing gear. It has 160 miles on the clock and with all these information about the proper way to break in an engine i feel a bit worried. Will this have a negative effect on my engine in the long run or should i just stop worry? The manual says that excessive use of the car during the first period of use should be avoided. Thanks
