hi was just wondering

1. do these cars burn off quite alot of oil

2. do they use a bit of water and need topping up quite regular

3. am i right that a t2 is supposed to run at 7 psi which is approx 0.5 bar what could i push it to safely or what do i need to do to run higher boost and approx how high

just like to say any help will be greatly appreciated and anything anyone would like to add that may be handy to know feel free really trying to learn as much about my frst so i dont get frustrated and bored like previous cars as i really do love my frst and want to make it really mint and relatavely reliable thanks again
