After I have done 186 miles do I do the oil change or an engine rebuild. This is not my first break in but I'm just wondering which one is a better option. I normally do engine rebuild. So what is the better option??

Thanks.
 
I let my car to be broken during the night on B-Spec Endurance race like Indy 500 or Nurburgring 4h, after this i do an oil change, chassis refit and engine overhaul. I don't remember exactly because i do this like a robot now, but it seems that it's possible to do both. What i don't know is if you change oil first and engine overhaul after you have a gain of power , or if the game deduct that engine overhaul only include oil change of course and sum it automatically.????

CyKosis1973 , i don't know if it's better to wait 1500 miles, to make a rebuild. If the game offer this possibility earlier ,it's because it must be enough with less than this and waiting more time or more miles do not increase the power after the rebuild....

If somebody tested all this already and have some reliables results to share , i'll be glade to know about. Thanks.

Have a good day everybody.
 
That wasn't his question...

@OP I'm not sure sorry.


The answer was indeed relevant unless you are too thick-headed to figure out this post recommended an oil change.....

To OP - I agree with ImprezaAddict that an engine rebuild is not necessary until a couple thousand miles (unless you like to bang off the rev-limited for long periods of time in races)

Rebuilds are only necessary when an oil change no longer gives you back your peak power - which is AFTER break in. A couple hundred miles you are still gaining power from break in.

I believe the recommended rebuild distance is around 3000 km or 1500 miles...

Just because his question was poorly punctuated, doesn't make it any less of a question. I answered his question, you just wasted internets...

Hi Praiano, how's life in Suriname?? You're entirely right my good man, the distance is likely to be different for each car.

For OP - There have been a few threads that have studied both oil changes and engine rebuilds. The net result being that engine rebuilds are required less frequently than oil changes 👍

This is one part where the game fails IMO. Oil changes in race cars should be done pretty frequently but full engine rebuilds aren't always necessary, especially not after only 1,000 miles or so. Part swaps sure but not an entire engine rebuild. When you can drive one clean race where you don't hit anything and you drive in clean air with a brand new car and it wants you to do an engine rebuild even though you've only driven 30 miles or so... there's something wrong with that system.

There is no life in Suriname , only work and frozen fish :ouch::indiff: , but good GT5 sessions by night and during the weekend.:):):dopey:👍👍

December back to Brasil till march = Less GT5 and + beach +surf + my young surfers kids ,and myself the old beach boy tuner of fake cars. :):) That means my garage will enter in hibernation during this time.👍 just the time to refill my battery pack.
 
To me, rebuilding an engine after performing a break in seems to defeat the purpose of a break in. I haven't tried this out in the game, but enough times in real life. You perform for example a 50 hour engine break in on a new engine after installation on a dyno and then you change the oil. That ensures all the friction surfaces are broken in (and engine friction stabilizes). At that moment the engine is ready to go and gives a consistent performance until of course its starts to wear. If you rebuild it, you have to break it in again since the friction surfaces from new pistons, bearings and so on have changed. Makes sense?

You do a oil change the second you get the car and HP will start going up. Once you get to around 150-180 miles and you will notice the HP has slightly dropped. Which than you do a oil change again and the HP will continue to climb until around 300 miles. After that I wouldn't worry about an engine rebuild because it won't be until the thousands and thousands range.
 
i do the first oil change on a new car before i take it out.. i send them into a endurance race on the suzuka 1000km as close to stock (just exhaust) takes about 6hrs and they usually will come out around 620.miles an have flat lined on dropping hp, do a oil change, modify as i want then ill do a Nur 4hr or next oil change around 1000.miles
some cars peak around 800 miles(street car) some around 1000(race car). i find doing it in these steps i get more miles after its fully tuned on peak power before it startes to loose hp or need a oil change.

this is only my method and can only say theres no book on this.
