    BREAK IN | What is The Strategy?

    Now that cars will start showing up next month, what is the break in strategy most prudent to follow?

    To be safe, follow the guidelines in the car's manual.

    Re: BREAK IN | What is The Strategy?

    First of all... Same procedure like every day with any car - never Rev high until the oil is warm. Second, First 1500 miles avoid high revs and aggressive driving. For myself - I stayed below 4500 Revs the first 500 miles then more and more often Rev it up. After 1500 I was using it for the full extend. Breaking in engines means also to ride NOT in a simultaneous Rev....try to drive roads which gives you the pleasure for going slow/fast and drive different gears.


    Re: BREAK IN | What is The Strategy?

    Be quick, not a lot of noise. Put it in neutral, roll it out of the garage and slowly pull away before the owners notice.

    There is no try. Just do.

    This is actually rule NUMBER ONE. Smiley

    Same here, staying below 4500 rpm the first 500 mls is a good advice, I usually try to follow this up to 1000 km (625 mls).

    Yes, country roads are much better for breaking in the car (not only the engine) than highways at a constant speed.

    I would also avoid driving on the track the first 3000 km (1875 mls) because you never know if something went wrong during production (screw not tightened well, etc.).

    Many people don't seem to know that the break-in period is not about the engine (the engines are actually one thing you really don't have to care about much as long as you respect Lars' recommendation with the oil temperature, especially on the GT3 and Turbos) but mainly because of the fact that IF something went wrong during production and/or if a certain part malfunctions because of possible manufacturing issues, it usually happens during the first 3000 km.

    Also don't forget that the brakes and tires need a break-in too, so driving at 100% from the start on a brand new car can be dangerous.

    Luckily, modern cars really don't need a perfect break-in period anymore but just keep in mind to take it slow for a couple of hundreds of miles, ALWAYS have a very close look at the oil temperature (no kidding here!!!), keeping the rpm figure under 3500-4000 rpm and then raise the speed and pace you're driving at but do not track race or drive at the limit during the first 3000 km. Then, you should be fine. Smiley

    Re: BREAK IN | What is The Strategy?

    Meh, just drive them however you want. Car companies don't make cars that can be broken while under warranty just because you drove in the wrong rev range too long initially. The tires need more breaking in than the car.

    I wouldn't worry about the car braking down but about worse performance and a shorter lifespan of parts (engine, drivetrain, tranny, etc.). If one leases the car, maybe not really an issue but for buyers, well... Smiley

    Another problem is safety. Like I said before, not everything always works out as it should and if there was an issue during production and they didn't catch it, well... Smiley Usually, problems occur during the first couple of hundreds of kms but it could take a bit longer.

    I'm afraid this report is not accurate.

    ALL Porsche engines are "cold tested" (pressure) and only one in 100 engines is tested warm on a dyno.

    The engine alone isn't the issue regarding break in but I think I explained it before.

    So basically:

    Warm up the engine properly, do not rev over 4000 rpm the first 500 mls, try to drive at changing speeds (= changing rpm figures below 4000 rpm) during that period and do not track race or drive at the limit during the first 1875 mls (3000 km). Also avoid prolonged full throttle situations during that time.

    Again: This isn't about the engine only but the whole car (drivetrain, tranny, chassis, etc.).

    You are a lucky guy my friend..... three hard weeks try to find a lot of sleep. Once that car is there you will not be able to sleep anymore because of constant smiles and Adrenalin shocks!


    Re: BREAK IN | What is The Strategy?

    You are talking from experience, don't you?  Are you still enjoying your new ride? I bet so.

    I actually sleep quite well at night but I'm not so sure about my son. He is so crazy about this car, you cannot even imagine. Kids...

    Re: BREAK IN | What is The Strategy?

    HAHA.... I think you are right with your son. When I was kid I would have been exactly like that. Especially on such a ride!

    Yep.... the car makes a lot of fun - I never thought I would be happy without the convertible. But being honest, never ever missed it, not even one minute. Funny - it seems that there is some truth with the sentence "only a coupe is a real 911" :)

    I had a lot of fun in the 991 Carrera S Cab I drove for a weekend, why should I lie. The weather was very nice (hot) and it was a wonderful experience. However, we only have a couple of nice weeks in Germany and I'm not the type of guy who enjoys driving a Cab at 10°C or when it is cloudy and below 20°C. So yes, you are right, I never missed the Cab again, not even my 997 Carrera GTS Cab and this was also the reason I didn't choose the Turbo S Cab, it just doesn't make much sense in Germany. My wife thinks differently and she may get one when her X3 lease runs out but I'm really not a Cab type of guy, never was.

    Now back to topic before we hijack this thread completely. Smiley

    Re: BREAK IN | What is The Strategy?

    Next week I have to drive some 1.200 km, mostly highway. But not only straight line, and traffic will probably bother me for at least part of the trip. Hence the Rev change is pretty guaranteed.

    The car now has 500+ km (almost 200 of which driven by Porsche mechanics to fix it!) and I'm not sure I'll resist pushing it - for just a few seconds -.

    I used to drive motorbikes since I was very little. At that time they always told me to break in slowly, but every once in a while give it all to "train" the engine to high revs. I never knew if it was an urban myth, but my bikes (several) always performed perfectly, also when compared to equal ones.

    I'm hoping you'll all comfort me that I can break the rule here and there ... or I'll go crazy during the trip! heart

    What if I happen to encounter, say an M5 or a Maserati or ..., how can I possibly resist the challenge!?! 


    Re: BREAK IN | What is The Strategy?

    Over my last trip, some little birdie who works for a company with a shield and a horse on it told me modern car engines have a lot tighter production tolerances, and each engine that came off the line go through a pressure test on the whole rpm range and that's when the components are bedded in, or 'broken in'. Years ago when they can't make parts with such tight tolerances, the engine do need an extended time to break in the parts.

    Having told me as much, the birdie also said common sense also rules. Don't let a new engine sits at a constant high rpm for an extended period of time and gives the engine time to warm up to operating temperature first before opening the throttle big time.

    Re: BREAK IN | What is The Strategy?

    Proper warm up is key - I've not run-in particularly any of my cars BUT when I start it up I drive the first miles as low rpm as possible until not only water is up but oil too -   Never had a issue with Diesel or Petrol engines or Oil-consumption kiss


    Re: BREAK IN | What is The Strategy?


    Re: BREAK IN | What is The Strategy?

    I never ever push the car if it's not properly warmed up.
    Not even rental or courtesy car, I just can't do it. I feel bad for the car surprise

    +1. 

    I don't go over 3000 rpm until the coolant temperature is halfway to normal, and gradually increase the limit until oil is up to operating temperature. However, these days with the low viscosity oil used in the motor, I wonder if this is too conservative...
