I use M1 10W-30 I am using Mobil 1 10W-30 oil right now on my 95 Z. Would it be safe to use German Castrol 0W-30 for my car? I have a very, very slight leak. Is it alot thinner compare to M1 10W-30 or i wont notice any difference?

if anything, it'll be thicker once it heats up. GC 0W-30 is closer to a 40 weight when warm and the mobil 1's 30W's are extremely thin. you're better off going GC no matter how you do it IMO. only one way to find out though. if it leaks, switch back but i'd be willing to bet you'll be fine.
