At the risk of sounding a little anal-retentive or suffering from a mild form of OCD (which could both very well be the case) I just wanted to put this out there and see whether anyone else knows more about this.

Here's the thing, I've bought an Alfa Romeo 8C recently and fully tuned it, after that I gave it an oilchange before driving it like I always do, then after doing about 200 kilometers (or roughly 120 miles) I gave it another oilchange (again like I always do) and a 3rd when it reached roughly 300 kilometers (yep, you've guessed it) since 300 kilometers (or roughly 180 miles) seems to be the point when any car reaches its peak amount of horsepower.

It's just a pattern I more or less use automatically on most cars when bought new and seemed logical (although the oilchange straight after reaching 300 km is just to see how much power it's going to end up with).
The 8C finally reached 658 Bhp using this method, yesterday someone online offered me another 8C for a new M3 and since this seemed like a good deal for me I decided to take it.
Again I fully tuned it (and a first oilchange), set it up exactly like the first one and jumped in the online open lobby and had tons of fun racing it and totally disregarded the mileage (like you would) and when I had done about 270-290 kilometers I decided to give it an oilchange and again about 20-30 kilometers later to get it to its peak.

Turned out it had 650 Bhp after that, 8 less than an otherwise completely similar car with almost completely similar mileage.
Is this difference going to be temporarily or permanent, can't do an engine-rebuild right now since the mileage apparantly isn't yet high enough for that.
Maybe someone can shine a light on this matter, maybe after rebuilding both engines eventually it's going to be evenly matched again.

And to be clear, I actually really like this aspect since it apparantly pays to maintain your cars properly, just wanted to point out it does seem to make a difference, 8 Bhp on this car, maybe much more (or less) on others.

What is the difference in mileage between the 2 of them? One might not be broken in as much as the other, I doubt PD modeled the cars to have different HP depending on how you break them in.

As I said, the mileage is near-identical (both around 310 kilometers), both are tuned the same, set up the same, etc.
The only difference is that one received a second oilchange after 200 kilometers whilst the other received a second oilchange after doing roughly 70 kilometers more.
In the name of science (and because the 8C isn't a punishment to drive) I've even bought a 3rd one (note to self, try less expensive cars for experiments...) and gave it the same treatment as the first and again it eventually achieved 658 horsepower.
So the frequency of oilchanges does really seem to affect how the car's broken in (as in the performance figures).
Again, whether this is permanent remains a question for me.

Update, I remembered I "abused" a F430 Scuderia (which means it didn't receive the usual "timely" oilchange after roughly 200 kilometers) and bought another one, again completely similar in upgrades but using my usual method and after "breaking it in" and achieving similar mileage it has a whopping 3 (...) horsepower more.
Again this might be perceived as trivial but I think it proves there's a difference depending on maintenance.
I only coincidentally discovered it due to having similar cars (don't have many similar models) and some of my other cars probably could've been more powerful if I "treated them better".
There are a few which have entered enduros and only received their second oilchange after doing much more than 200 kilometers.
Maybe it only affects certain type of cars ("fragile" exotics in this case) and may be irrelevant on more ruggedly engineered ones.

Nascars all reach 892bhp and I have almost 10 of them, now if different model cars all get the same respective power what sense would it make to have different power in two exact same cars?

It takes 200 miles to break in a car which is around 330-340km so it's highly likely one isn't broken in yet.

I've got all NASCAR cars and all are fully "broken in" and they all have exactly 905 bhp so you still have some way to go I guess (or using a different method........).
It's not a question of making sense that exactly the same cars have different horsepower levels due to randomness, my question was whether PD implemented a system whereby carefully maintaining your cars isn't just a pointless exercise like the carwash for example is but it's worth paying attention to the mileage and regularly change the oil especially in the beginning stages of ownership.
Both 8C's and both Scuderia's are "broken in" exactly the same, since they both have almost identical mileage (otherwise why bother finding out) and yet still have a different amount of horsepower.
I may ofcourse be wrong and it's due to something different (God knows what however) but it isn't the difference in mileage, and I'm not sure it's the same for each single model or type of car.
 
The engine re build and chassis rebuild are broken in this game...you fix them all up..and do 1 race and dont hit anything at all. and it need chassis repair..


in a race car its even worse! chassis and engine all new..1 race...500,000 for each.....

WTF. i ignore this feature becasue of how stupid it seems to be.
 
How did you come up with the mileage figures to change your oil at? Do you think it could be different if you changed it earlier? I myself have only done the oil changes on cars right when I buy them. I haven't kept up with when I do my second oil change. Most of my cars out of the 100 or so I have have only one oil change.

I've only started to see permanent power loss on one of my vehicles, and it has 5000 miles on it (Nissan R92CP used for B-Spec money earning when I have to clear my DVR). Seems pretty realistic to me, given that those 5000 miles are being run all-out.

You can't make the argument that real-world cars don't need an engine rebuilt to restore lost power until they have several hundreds of thousands of miles, since those miles aren't being accumulated in an racing situation. Many race teams will rebuild a motor after each race.

No. Do one race and you can do the repair because it isn't 100% perfect anymore. It's probably something like 99.98% perfect but not 100% so the option is available. Much like in real life you have a freshly painted car which you take for a drive and it gets one miniscule stone chip under the rear bumper - you can get the entire thing resprayed. Nobody says you have to.

It's just something I more or less instinctly got used to doing on most cars, not that consistently but after about 200 kilometers I figured the initial power increase of the first oilchange might have perished and after I found out most cars didn't increase their amount of horsepower after doing roughly 300 kilometers I performed another oilchange mainly to see the "final" figure.
There's hardly any technical logic to it I guess, just a pattern I got used to.
Was just curious whether I stumbled onto something and if someone had any clue if this could be true or not (and the examples I gave earlier do seem to illustrate at least a temporarily difference).:)

I don't make that argument, the game simply won't let me rebuild the engine (chassis, yes, engine, no) at this point on those cars, which to me suggests they need more mileage before they need a rebuild, not according to me but according to PD.;)

Update, a few miles later and the engine rebuild now does seem possible, will get back on this issue later.

Okay, first sorry for the double post/bump but I promised in my previous post some time ago I would get back on this nagging (albeit minor) issue.
I was puzzled for some time as to why similar cars (with completely similar tuning upgrades) achieved different amounts of horsepower after having done exactly the same amount of mileage (the 'break in' period).

The differences were very small (a few hp) but present and after doing some more miles in the cars with less horsepower they eventually achieved the same amount as the other cars.
Why these cars took significantly longer (as in more miles) to break in still wasn't clear to me but then the penny slowly dropped.

I've been using those cars with less horsepower online during their break in period, unlike their counterparts which I broke in offline.
Which leads me to conclude (I think, not sure ofcourse) the mileage done online doesn't affect the performance increase over time as much as the miles gathered offline.
By which I mean, to achieve the same results (eventual peak power) you'd need to drive more miles online than offline.
Whether this is correct or not I simply don't know, nor do I know whether it also affects other aspects like engine/chassis wear, etc.
Anyone else who could confirm/explain this or experienced something similar?
 
I remember trading a car away and then getting it back and it wasn't running at peak performance again until I overhauled the engine (just an oil change was not sufficient). I don't know why that happens. Though, an engine should be able to be restored back to full HP up to 6677.33km (4149 miles).
 
Sorry, wrong.

I have also used a few cars online, some with a double-digit 'swtiched to' stat, that still show zero miles. So instead of making such a stupid post, why don't you go into some detail? Do you have an alternate theory as to why these cars have zero miles? Or do you think he and I are making this up? Or maybe you're just trolling? If that's the case, then bugger off.
 
Online mileage only accumulates during races and not from just lapping in a lounge. That's how its always worked for me anyways.
 
Do you guys do an oil change as soon as you buy the car? In some cases it can give up to 50bhp, depending on mileage etc. Its worth the few credits it costs.
 
Interesting thread.
I'm not to fussed personally if the car loses a few HP but I'm sure some people like to keep their garage all fully powered.

I do. The Gran Turismo "performance" oil is always better than the fresh premium oil and the boiled up chocolate juice in the used standard vehicles.

This, mileage is only gathered online during actual racing (sometimes it doesn't though but that's probably just a minor glitch or connectivity issue, in theory it should).
But as I mentioned before, this mileage doesn't appear to be exactly the same, as in the effect it has on the car, than the mileage done offline.
The results may differ very slightly but it might be something people like to be aware of.
It doesn't affect the eventual peak power, it just takes longer to break in a car if you drive it online it seems.
So my initial theory that some (or all) cars being 'high-maintenance' can be thrown out of the window, online miles just seem to be shorter than offline ones.
 
Hehe, my X1 has been hard at work grinding, after 47,976 km's, and oil changes(no engine rebuilds) the car can't get into the 400's.....dang it.

That's just engine wear which has nothing to do with this issue, apart from maybe taking longer to wear out an engine if you use it online.
