Using High mileage oil in a new car ??

[Baveux]

Any advantage or disadvantage from using high milleage oil in a brand new car ?

Just a waste of $$$. Castrol GTX, Pennzoil PureBase, and Chevron Supreme dino oil will work just fine.

The advantage is that they are usually formulated at the top of viscosity range. I.e., xW-30 are usually around 11.5-12. In addition, some use good amount of esters, which is a nice bonus.

These are two things I really like about the high mileage oils. And even though my experience with Maxlife didn't show great wear numbers, it did hold it's TBN very well and it's viscosity. So I suspect that the other high mileage oils would do well in those things too, plus offering good wear numbers due to their better antiwear packages (esp. Pennzoil HM with it having both boron and moly in it)

The disadvantage is that they cost as much as the synthetic blends but have no usual ACEA A3/B3 rating of the blends.
