That was a correct answer, because "bedazzled" means the oil has tiny metal particles from blown bearings.Seriously? The poster may have a serious engine problem and this is how you answer?
Oil is oil and we all know why VW changed their oil specs.Point of order... VW recommended/recommends 5W-40, but required/requires oils with the VW 502.00 specification.
The oil that OP used is 5W-40.
The Mobil1 European Car Formula (meeting the VW 502.00 spec) I've used for both of our Mk5's for 14 years now is 0W-40. Not a hint of oil usage between changes.
But then we've always lived in the Norther Tier -- Maryland, Ohio, and now Colorado.
Where do you live?
You may not be familiar, but "bedazzled" refers to when bearing wear has started to leave little metal particles in the oil filter.Idiot reply!
No, I am saying that if you reduce the viscosity, then you have to increase the slipperiness of the oil.Well respectfully, we don't all know why. Are you referring to 502.00 as the "new oil spec"? As of 2005?
Please understand, what you're saying makes sense. If you understand more about this stuff than I do (which wouldn't be tough to do), by all means make your own choice. I mean that.
But for us lay-people, I think sticking with the recommended spec is the best choice.
Again not to put too-fine a point on it, but the Mobil1 ECF I've used for almost a decade and a half is 0W-40.
