Does mileage affect full potential?

Today I wanted to do an experiment and modify two identical cars in the exact same way to see if the outcome would be the exact same. My choice fell on the Mitsubishi GTO Twin Turbo '98. The first one has a mileage of about 16.000 km and the other has driven about 60.000 km. In GT Auto I gave both cars an engine and body overhaul and fresh oil. In the tuning shop I purchased every little piece that increases bhp and performance including the three stages of engine tuning. The outcome was that the car with a mileage of 16.000 km had 701 bhp and the car with 60.000 km only reached 694 bhp. So my question is if the high mileage on the latter has affected the full potential of the car? Same model and same amount of modification.

Well, first off, oil change comes with engine rebuild, so you should stop changing the oil first if you are, you'll notice after a rebuild you cannot change your oil until you drive the car.

I never though of your question tbh, I just assumed the rebuild's restored brand new performance, so I'll have to check to make 100% if you're using identical models, no offense.
Which specific Mistsubishi GTO Twin Turbo '98 model is it exactly? Or is it exactly that?
 
Yes. After (apparently) 20.000 km permanent power loss creeps in - meaning that even an engine restoration doesn't give full power anymore - and gets worse with more mileage. No idea about the mileage of maximum power loss, if there even is any.

If that's true, you could guess maybe 353,000kms. (trophy)
 
I know it would be in the 200k mile range for sure. As for when you start seeing power loss it depends. If you leave the car stock then you can see it in the UCD with the difference in PP between two cars of the same model with differing mileages, the one that's lower will have a higher PP and that difference starts occuring at 3000km. 👍 When it's rebuilt, then you usually find Greycap's comment of 20,000km/12,500mile to be pretty accurate. My Accord from the FF challenge has 11,378km (over 7000miles) and that still has full power, and I rebuilt a GT No Stripe with 6000 miles on it and that had the full 874hp. 👍

Ok, thanks for the oil tip. It's exactly the GTO Twin Turbo '98 model, not the MR.

Thanks for confirming that.

This is correct, just over 20k and the hp starts dropping. Permanent loss progressively.

Well, over 13000 miles the hp doesnt get fully recovered according to certain people. I havent tested myself, but i only aim on low milage cars.
 
I just confirmed 20k shows permanent HP loss. I buy multiple editions of cars I like and do mileage/HP checks on them. 20k and the HP goes away. 130k is most probably where maximum loss is reached, where they stop loosing HP, but that I have not tested and cannot confirm.

Oops did you mean 13k? In that case, maybe, could be where the first HP goes, ill confirm after work. I've only noticed as of 20k.

Yeah 13000 miles, check it out so we all know for sure.
 
Be carefull with your car you are not useing tho.

I have a corvett that I love driving. It was one of the first cars I build on the game. Its a full RM maxed out car. I have since replaced it with several other vett's for specific track setups, however I kept my original because I cant seem to let it go.

That being said.

I parked it with 15k miles on it, it had a fresh rebuild and wash.
Numbers were 900hp give or take.

It had not been used in 6 months and its down to 840hp.
I have noticed the same thing with other cars Im collecting.

Rust I guess.?
 
Mileage does affect full potential, you are not wrong. Use the 67' BDay ticket or any vintage ticket for that example. You will get a 0 mile car, now max that out. Drive it around Daytona for approx. 60 laps & reoil. Now take the same car thats not 0 miles & reoil. Look at the power difference in PP & HP. I have seen a Cuda with 300,000miles max at 824hp but then my 200mi Cuda (just broke in) hits 972hp. And I always oil before I rebuild, I don't care if it appears that you don't need to waste your time or money. But this game is full of flaws and I'll spend the whooping 2500cr to do so.

You mean HP loss from collecting dust? Weird..

Can I be your lube tech?:lol:

So the only thing that I'm wondering is at what mileage does an engine rebuild fail to bring a car back to its peak power and does this vary from car to car or is it a fixed mileage for all cars?
 
I've got about 14K miles on 1 of my FGT, and permanent powerloss is starting to set in. I ussed to be able to get 936Hp out of it. Now with a rebuild I'm lucky to get 922hp.

I think it varies car to car. I know a NASCAR never loses hp after a rebuild no matter how many 10K's or 1000K's you put on it.

Yeah that makes sence, i think around 13k miles you dont get full power back.

Wow I was starting to think that this only applied to Street Cars. As my NASCAR has never dropped off.

I don't have much to say, just reading on what people are saying :-) I'm starting to have this problem too with some of my cars. but I have 2 Tony Stewart cars one is the one I bought when I first put GT5 in PS3 that one lost HP it was 892 now its 891 and yes I did oil when I bought it then overhaul when it needed it. I'm not sure how many miles are on the car but I think it's around 9,000 to 10,000 miles maybe more.
 
As it has been suggested earlier it seems that cars can loose HP while being stored in the garage but I can't confirm that. However, I just bought four cars in the OCD that I already won in some of the events. To be precise I refer to the BMW 2002, Lancia Stratos, Lotus Elan and Mini Marcos. When I won these cars I did perform an oil change and I have never driven any them so 0 mileage on each one. As mentioned, these cars are in the current OCD with 0 mileage and I bought the above mentioned models again and performed an oil change on all four of them. The weird thing is that those I won in the A-Spec and B-Spec events have slightly less HP than those I just bought in the OCD. Can someone tell me what causes that? I'm puzzled as something else must affect power loss besides mileage.
 
The ones in the OCD are preset to go to max hp. My Veyron that I won in the GT World Championship needed to be broken in to get it's 1256hp, but the other one's I've bought from the OCD have gone to 1256hp with 0 mile. However, they don't gain any extra hp after driving them.

What's with the prize cars with 0 mile? They need to be broken in, right?



EDIT: What an unnecessary question........:banghead:
