engine: very small roughness on metal surface, will whip off in the first 1-2 hundred miles
oxygen sensor (sets the fuel/air mixture, therefore affects acceleration and fuel consumption): when new, it needs to get "burned" in order to operate to the specs. The hotter it gets, the faster it burns. I'd suggest, passing the first hundred miles, start shifting/keeping the revs higher than usually (above 4000rpm) and drive so 2-3 gas tanks. don't switch to synthetics before 1000 miles, a new engine needs to run on mineral oil |

Hey guys, this is just a theoretical situation. Its not like I did it or anything.
But what if someone got their car with say, less than 15 miles on it. drove it slowly home for 15 miles. Then drove a 100 mile road trip in going some 110-120 the whole way, just because it was the first time he/she could. What kind of problems might he/she need to go get checked for at the shop? |

My Yaris is my 5th new car. I've broken in all my cars by driving them hard straight off the lot. My Yaris has 115 hard km's on it, WOT to redline in every gear. The reason I do this is because cars that go thru a hard break in period will be more powerful than a "normal" break in. All 3 of my SLK's were broken in this way, and was faster than the others at track days. I've never had any problems with engine reliability either.

well, I agree for the first few thousand miles you should baby it and vary the RPM range, most of the breaking in is done at the factory these days, but you can never be to carefull...also, if you plan on shifting at higher rpms and flogging your car, keep in mind part of the break in process is seating the valves, and if the valves seat for the 3k-5k range and you constantly shift your yaris at 6k, its harder on the valvetrain and you wont get as much performance from the engine. I have not verified that on a newer car, but thats how they break in older muscle cars...I think the best way is to drive the car how you intend to drive it, but avoiding keeping it at the same RPM range for long trips (switching from 4th to 5th every now and then to vary the rpms).

if that is not a matter, drive it as you like from the very first mile. it's my advice as a mechanical engineer, two things seems to be important: use mineral oil for the first thousands miles and never rev high a cold engine. rage2: what you are saying is all about the oxygen sensor, the hotter it gets the faster it starts work at his normal range |

I really never gave the car a break-in since they come already tested from the factory. I just droved it hard a couple of times. I just think my engine came with the expected 106hp since we know hp factory numbers are estimated.

No, I'm not talking about a cold engine vs a warm engine, I'm talking about 2 identical engines, one broken in "easy", and one broken in "hard", or drive it like you stole it. The engine broken in hard will be more powerful.

I worried about the break in period as well. I drove mine as prescribed in the manual, varying speeds for the first 1,000 miles. I changed to Mobil 1 at 2,000 and follow factory intervals of 5,000. Now at nearly 15,000 miles, I've never burned any oil and get great gas mileage.

The only time I run a easy break-in procedure on a car is when I'm building a new motor from scratch, for about 100km, to ensure the rings and walls are contacting smoothly. After that is an oil flush, then hard break-in!

Back in USA in days!

When I test drove a yaris it only had like 30 miles (I went home with it that night) I left the lot and waited till I came to the first stop and then let her loose, I chirped the tired shifting into second and beat the hell out of the car for about 15 minutes. Currently have 11,000 miles on car and no problems.

I broke mine in with a combination of long highway trips and red line WOT shifting in between. Currently have just over 3200 miles and the oil level hasn't ever gone down a drop, which indicates rings are well seated and the break in was a success :) I think people (myself included) stress needlessly about the break in. Just think how many cars are out there that people buy new and aren't even aware of the term "break in" and drive their cars for hundreds of thousands of miles.
