Royal purple XPR 10w40 question

Hi,

I'm almost due for my oil change and one of my friends friends... has Royal Purple XPR oil for sale, he'll give me 10qt for 100$ which is similar in price for regular PR or amsoil (I don't pay tax and shipping to this guy)

I have a couple of questions..
1. Is it good for my boxster? XPR is racing oil.. I don't race, my boxster is a daily driver to work and back

2. I'm worried about leaks.. car is 10 years old.. I have zero history of work done.. I'm worried that RMS could start leaking (I read that PR clean it out very well) I don't have 2k for RMS and clutch now I'd rather have sludge keeping it from leaking for time being

Should I get RP XPR? or should I just stick to M1 0w40 that is in the car now?

Thanks
Sasha
