Guys, changing your oil is a great way to get a few extra horses (Only 250cr!!!). Any thing between 5-10Hp can be got.
When you drive your car you actually run in your engine
& your Hp increases!!!!!!!
I've noticed my cars increasing 1-2 Hp per race up to about 10Hp.
I change my oil every 100K or after every endurance race just to be on the save side.
Your car will eventually start losing some Hp because of wear but it will stop after so many K's are knocked up & you won't lose anymore. :thumbsup:
