Fluid capacities are like speed limits, theres a good reason they are posted and expected to be followed. Just because you can go down a road exceeding the speed limit way beyond posted limits, and everything comes out the first time doesn't mean that if you keep doing it that nothing will happen. Bad habits can and will come back to bite you in the ***. They actually have many similarities, speeding uses more gas, overfilling uses more oil, both costing you more money, speeding may get you somewhere 5 minutes faster in the short term, just like some misconception that overfilling your engine'* oil pan can lengthen your engines life, speeding raises your chances of being killed, just like your unfortunate misconception will kill your engine.
Same principals, and if your smart, you respect them, and if you don't, you pay the ultimate price, in what ever form it decides to rear its ugly head.
Your choice I suppose, but I imagine its the same as telling someone they should go drive 100mph down a curvy blind-cornered road just because its fun and then you don't warn them about the consequences of it, but are recommending it just because YOU haven't had a problem with it. Its NOT good advice, its NOT to be followed, its your right to do whatever you like, but you hold responsibility for the advice you give.
Terribly sorry for getting so off topic.
