check the top of the master cylinder
dot 4 or dot 5
You shouldnt mix the two...
I have dot 5 in my 05 which is silicone based
my '12 has dot 4 which is not, so don't spill it on your paint
As far as engine oil, I run synthetic in everything, I consider it cheap insurance as it gets incredibly hot here.
Don't worry about checking what it has had in it.
Get it hot, drain the oil and change the filter
Put in whatever oil you think is good enough
Plenty of info/arguments on synthetic vs mineral oil, pick one
dot 4 or dot 5

This is all correct, but just let me emphasize, DO NOT mix Dot 4 and Dot 5 it will render your brake system useless.
Make sure you get the right fluid.

Yeah, I was going to mention also and I could be wrong that there are different internal components, that is rubbers and seals that need the correct fluid, dot 4 or dot 5

That may be true on some systems since I have seen aftermarket units that say DOT 5 ONLY.
