I posted about the tire wear bug earlier, I might post about the oil change bug too.

Any car you win or buy, new from the dealership or used, will gain 5% HP from an oil change, even with no mileage and the oil has the pristine orange-yellow color in GT Auto. BE AWARE. The DLCs don't have this bug.

PS. We need an official bug thread stickied and updated.
 
Not a bug, this has always been the case with GT games

EDIT:
Taken from the Apex book you get with the CE and SE

High-output engines put immense strain in their components, particularly their internal parts, so high performance engine oil is absolutely essential. Engine oil functions as a lubricant, a cooling agent and a barrier maintaining an airtight state. If the oil is not able to coat surfaces properly, the cylinders will not be able to maintain pressure and the engine will lose power

So I guess what PD is going for, is that you chance the stock oil with some high performance oil...

Didn't know it always been that way, I never really played GT3 and 4 seriously, 1 and 2 are too far back, tho I doubt a Ferrari comes with cheap organic oil. Well if it's not a bug but by PD's design it's even worst then.

Worse, how so?

Though I do agree with you that the likes of Ferraris undoubtedly comes with a high performance oil already, but that is hardly the case with ordinary cars...

Have you noticed the power increase of your new cars as you drive them the first couple hundred km?

:sick: really?

Are they kidding or what? So i never know if my hotlap is rellevant and if my car is the same as when i did that previous time etc... please tell me you are joking? Is there something else we should know?

Well, just as for brake fade and brake upgrade in GT5, GT5 doesn't simulate engine heat first and foremost, and cheap and high performance oil have a negligible friction coefficient difference between the two under optimal temperature, racing grade oil wouldn't change the power output.

That's actually completely realistic, engines have a break in period. I dunno how I feel about having to change oil on new cars though, that seems kind of unnecessary. I'm going to start doing it now, though :P

A stock car from any manufacturer would contain oil that would not restrict the car from making its optimum horse power.

Infact its not about the grade of your oil its about decent oil and regular changes to keep an engine healthy and up to its optimal performance.

Oil will not rob an engine of horsepower the way this game does.

It's called the "break-in" period.:rolleyes:

And to simulate it the have cars gain some power over the first 150 miles, (rather than a more life-like 2000) because we don't drive most of our cars 2,000 miles.
The power gain after the first oil change, is to simulate the final stage of the break-in, and also, the small gains found from putting pure racing oil, (such as royal purple) in an engine over whatever may have came stock.

All cars have less than advertised power from the start - surely someone posting in here has noticed this. And coincidentally, the "break-in" puts them right there.:)

Long story short, to go the "realistic" route, you're not supposed to change the oil on a brand-new engine. (life-like would hurt your performance as most high-grade synthetics can prevent proper engine break-in)

Tell that to the SAE tests done. For example, Castrol Edge leaving 1/8th the cam lobe wear as Mobil 1 non-synthetic. Go Figure, they actually do perform Differently.
 
Man, some people are wondering about everything. What´s the matter with oil change in a new car? It doesn´t hurt and its part of the game design.

Anymore questions?

It matters ffs.. when a friend tells you "i did 1:05.334 on Tskuba", you have to wonder if he changed the oil, if he drove it 2000 miles, etc.. :yuck: 👎 And it will always be in my head that my car isn't always the same.. it's stupid design, i'm always for realism but there's no room for this! Stupid stupid..
 
^^ So you wnat the game where you don't ahve to change your oil? too much realism to do so?
or am I missing your point?

It isn´t stupid. It is design to get most normal cars with standard oil and you can add performance oil to increase the performance. Works in real life, works in GT5.

And I think that even Ferrari doesn´t sell its cars with high performance racing oil.

By the way: if you think your friend changed the oil, you should do the same...too easy to talk about it.

Yes, it's not too much realism, it's unnecessary realism! For time-trialing you always need perfect conditions and same conditions for everyone.. it wouldn't be bad if you only had to do this for the "career" but not online and in time-trialing..

Well at first I tought it was a bug, but it seems it's intended, this is somewhat annoying, I have to "change car" and change the oil for every car I buy and win. I like changing the oil after hundreds of miles, but straight from the dealer?

Then don't change the oil on new cars if you don't want to have the extra boost in power?

Ive not tried it with new cars but any second car you buy will also benefit from a Engine overhaul. Dont bother with the Oil change its thrown in. After the overhaul a second hand cars power increases by about 11%.

I think 11% is the maximum power a car can loose but I cant prove it yet. When I get to B-Spec endurance im gonna buy a second hand car and get bob to kill it in some 24hr races and see if I can get below 11% but I doubt it.

It's hardly the difference between a Stage 2 and 3 Turbo kit, is it? Do some back to back tests that prove changing the oil has any effect at all on a Tsukuba lap time, or even a longer circuit like Suzuka, and then I'll apologise.




And in the same sentence I'll tell you that 250cr for an oil change isn't exactly breaking the bank.

Finding something you don't like about GT5 then blowing it out of proportion must be the 'in' thing this winter.


Oh and of course your cars will be different, that's realism; Have you read about how varied the power outputs of the R35 GT-R were when they put a selection of randomly picked customers' cars on a dyno?

I'm doing 370z on Suzuka these days.. i'll change the oil and check the difference in lap times.
It's not blowing out of proportion, it's just stupid. Can i at least check how much horse power do i have etc?

You're suggesting that a car with an oil change will be noticeably faster than the same car without around any circuit. I've just changed the oil in my newly acquired 0 mile Evo Super Rally car, it had 312bhp before the oil change and 324bhp after. It's really not a big deal, stupid or not, it's not going to be the difference between winning and losing, and if it does translate into decreased lap times you're talking in the region of 0.01 second, if that.
