Anyways, at one point someone told me that stock is considered with the oil change boost and I couldn’t wrap my head around the reasoning behind that statement anymore. I had once naturally assumed that this was correct while I played GT5 because everyone is always saying go get an oil change as soon as you buy a car. As far as I am concerned now, since playing GT6 and having put more critical thought into it, the oil change upgrades the car with a temporary, rather magical, 5% HP boost.



Cars from the dealership come with stock / OEM oil and HP levels. These stock HP levels are the ones listed in the dealership.



This stock HP level is also the one that corresponds to those of real life cars: e.g. the HP, before applying limiters, on a real NASCAR car is roughly 820 to 850 HP. The stock NASCAR car which you buy from the dealership in GT6 comes with 849 HP. The new BMW M4 Coupe is listed as having 425 HP in the dealership: both in GT6’s dealership and in the real world.



The oil GT Auto uses is super exaggerated, almost enchanted, high-performance oil. XP



Therefore what should be considered stock? A stock car with stock HP is a car between 0 and 5000 km that has NOT had a fresh oil change to boost HP in the past 300 km.





2 – Are oil changes worth your time?



Unless you are absolutely set on increasing a car’s HP, no…oil changes are a great waste of time. You can completely avoid them by performing an engine overhaul every 5000 km since the engine starts to deteriorate at 5300 km (300 km after the oil begins to deteriorate) and the overhaul includes an oil change. If you are one of those who think that stock includes the 5% hp boost and you are not allowed to increase HP permanently via an upgrade, then you will have to change your oil every 200 km or so which means up to 25 times per 5000 km! Wouldn’t it be simpler to install an ECU (over similar small upgrade) and apply power limiter? Yes; but then your car definitely wouldn’t be considered stock. Funny how a permanent 5% HP boost is not considered stock, but frequent magical oil changes is still considered stock.
