sorry mate i dont think i can use 0w-40 my car is 28 years old, that would leak for sure. Plus i have 130k miles. Engine requires 10w40 or 15w 40 only, must be semi
15W-40 used to be spec'd for my BMW and even 20W-50 for my 27 year old Porsche but all European made cars no longer spec' these dino grades, nothing heavier than 0W-XX and 5W-XX oils are now spec'd and have been back spec'd at least three decades.
0W/5W-40 are not necessarily lighter at operating temp's vs 10W/15W-40 oils and therefore I wouldn't automatically assume oil leaks will crop up that weren't already present.
I appreciate the culture with heavier than necessary motor oils in OZ; I'm just providing a technical answer to your assumptions.
yeah we like to use thick oils,down here. Just checked 5w-40 costs $65 for 5 Litres. Any oil under 10w is $60 plus. We also dont have full dino's under 20w 50, only semi synthetics and full synthetics
