i've managed to find a great deal on 30 litres of motul 0w30 motor oil, i realise that this is VERY thin and my motor is starting to age a bit now (140,000kms). reckon that weight oil would be safe to run in this motor??

i'm guessing it may leak a bit, but i'm not sure, just wondering if any of you guys have had experience with similarly rated oils. thanx!
