im sorry im asking so many questions, but im finally getting my car this week, and i just want to make sure everything goes right.

How exactly should i break in my car?

-what should be my max RPM?

-how many miles is a good break in

any other info would be great

 

I've never followed break in periods. All my friends that build motors never follow break in periods and a lot of them swear that the harder they run them from the start the stronger the motors are. Now these are usually N/A motors, I don't know if turbos would differ.



But as far as break-in. It's not what max RPM. The key is to fluctuate RPMS and not keep a constant speed. 500-1000 miles should be more then enough.

 

i never broke in my sl55's, and both of them had major problems. they both ended up being lemons. i drive my cars very hard, and i think that may be the problem ... i dont want to take any chances this time

 

The manual says 2k miles for under 4800 RPM... I would just go 1k

 

I followed the manual recs for break in period for the first 1000 miles then I limited revs to ~5000-5200 for the second thousand miles. My oil usage has been much lower than what others are reporting (1 quart/5000miles). I dont know if there is cause and effect though.

 

I have always followed the manual's advise on break-in. My theory is that the people who design and built the car know what is best. Why would porsche advise a 2k break-in if this was not in the best interest of the buyer of the car?

 

Break your car in for 2k, keep your RPMs 4500 and under for the first 1k then gradually increase it from there on, vary your speeds and roads, shifting, etc.

 

thank you

 

shoot me in the ***

 

Hey SOON,

you say you don't follow break in periods, I'll bet you would if you just bought a $120,000 porsche........

 

I bet.

 

I spent over $135K and did not "break it in" according to the factory specs.

See this link and let me know your reaction.

I have used this technique on all my cars and my Ducati and have had no problems whatsoever. In fact none experience any real oil consumption (contrary to what I have heard posted here and otherwise). This may account for that.

 

i was also going to link that article here, but of course this raises a big question: If breaking in an engine is about ensuring a good piston ring seal, and if this is supposedly accomplished by running the engine hard when it is brand new, then why do manufacturers tell us to do the opposite?

The theory seems sound, but I don't know the author's credentials. And it is awefully hard to make the decision to go against the manufacturer's recommended break in when it could make or break your $130k car.


deeroff: have you ever NOT broken in a vehicle using the suggested method in the article? and if so, have you noticed a difference over time?

 

I used to baby my cars according to manufacturer's guidelines and - subjectively - I think there is a difference.

I had a 2001 and a 2002 E55 and babied the first one and killed the second and it was noticeably quicker and had zero oil consumption. Of course, that could just be the standard variation. Same deal with my Ducatis -- that is the end of my "experience" however.

Of course, instant gratification is worth something as well.

NOTE: I do take it easy on the running gear for the first few hundred miles (brakes, gearbox, etc.) -- maybe that is the REAL reason the manufacturers say to break it in -- they figure that you will do it for all components -- but if are not given that directive for the engine, then it is likely you will beat on the brakes, gearbox, etc. including the engine.

Thoughts? Comments? Questions?

 

i only broke in for first 1K...FYI - some cars are taken off the line at PAG onto the Atuobahnd and FLOORED to the limit as part of QC...
