since when?
if you think Harmlu is barking up the wrong tree why don't you offer some constructive advice
These engines arent oil sensitive. You can use any 10-40 5-40 5-30 oil in them. I would stick to 5-40 or 5-30. Now compare that to some diesels that need LL-01 or LL-04 or vag spec 505.00 or 501 or even merc 229.5 etc etc, If you don't put those accredited oils in then they will get damaged and warranties etc. These cars need oil when run low they damage, Show me one thread where a car has been damaged from using the "wrong" oil.
We can just throw about statements without backing them up. He provided no evidence either. So chill.
Oh believe me, I'm very chilled
