High mileage oil?

[jprins23]

So does anyone here use high mileage oil? I've been using full synthetic and was wondering if high mileage oil would suit better in my trucks old age. Any knowledge? 167k

Just keep doing what you’re doing. If your truck is running good with whatever oil you’re using, stick with it.

I started using Royal Purple when she was new in '05, then moved to Mobil 1 High Mileage Full Synthetic a while ago. I haven't had to tear her apart yet, so I can't really say much about it's effectiveness (then again, maybe not having to tear her apart is testament enough!).
