I'll be using Mobil 1 again next time, and that should help me sort out whether the consumption is due to the Platinum or 102,000 miles.
I am using 0W-20 Platinum in a Vibe with no oil consumption.
And the answer to that is.......

I stuck with it and just did the second change last thursday, so we shall see what happens.
Voilà
Sometimes when using a brand consistently when you change brands the new oil cleans off the previous oils anti-wear layers and thus opens up little gaps that weren't present before.
Once the new oil lays down its additives the consumption should cease b
As a data point I use a different brand of oil in every vehicle i own at every oil change. I even mix brands and grades and I've yet to see any consumption in any of them.
I really don't know why other than perhaps mixing oils makes the anti-wear layers more resilient because of the different additive packages(guessing).
So op I'd not worry whatsoever. Give it a few intervals. If it continues try something else.
