Engine Break in
There are a few methods of breaking in motors.
One is to beat on it as it is supposed to help seal the rings better, the other is to not drive about 4-5k rpm for about 1-2000 miles. using dino oil for 500 then switching to synthetic. Any thoughts on breaking in a new 135? |

Since no one has given an opinion yet, i'll start:biggrin:
MY engineering backround tells me that everything should be worked in gradually, and that's everything. Put the motor into all rpms and all gears at all speeds. Don't floor it right out of the showroom, let things loosen up a bit then push it a bit farther.

I have done the 'beat on it from the start' break-in on one new BMW and burned a quart of oil between 4000mile oil changes. I tried following the recommended procedure and had no oil problems on 4 new BMWs. I'll be following the 1200 mile <5000rpm varied speeds break in procedure. |

This isn't a very good war...no action and excitement and flaming. I'm disappointed

When I received my 135i I didn't revved it past 3,500 rpms during the first 1,000 km (621.37 miles), 4,000 rpms during km 1,000-1,500 (621.37-932.06 miles) and 4,500 rpms during km 1,500-2,000 (932.06-1,242.74 miles).
It was the greatest exercise of self-discipline I made in my entire life. Apart from that, I never rev the engine it too high when it is still cold and I never stop it just after "pushing" it. |

i don't have a strong opinion either way but when bmw drafts its recommended break-in procedure they aren't interested in getting the last drops of HP from your engine ... they are interested in minimizing their warranty claims. the two don't necessarily go hand-in-hand...but maybe they do in this instance.
another example would be the extended oil change recommendation it all comes down to how they are affected monetarily.

I've never heard "beating" on a new engine recommeded by anyone, but many suggest steady state rpms arent ideal either (like on the freeway). I read putting the engine under 2-3 second short bursts of heavy throttle every few minutes or so during the first 500-600 miles helps seat the piston rings. (After its up to temp of course.) I did ths on my 06 TSX and it was very stingy on oil after the first few hundred break-in miles. (some oil cosumption is normal when a motor is brand new.)

Well it shoulndn't take too long to warm this engine up, considering its history of overheating. Not sure what I will be doing, might depend on if I lease or buy.

Seems everyone I know who went the more aggressive break in has a car that dynos stronger than the average. I have no idea what their oil consumption is like.

+1 i have broken in many of my cars by beating the snot out of them from day 1 and they have ultimately performed better on dynos and on the street than their babied counterparts. Thats just me.

I don't nessesarely beat on the car but i do a systematic series of % rpm and throttle pulls in the first 100 miles to seat the rings always had very good dyno results.
