I took back the Pennzoil Platinum I purchased the other night as I found Pennzoil Ultra Platinum today for $8.00 dollars less a jug (5ltr). I was a bit concerned not seeing the green Dexos sticker/logo on the front but when I checked their site, it says it meets/exceeds that standard.

This oil is likely overkill for my wife's 3.6 Chevy Impala, but for the price, it was a no brainer in my opinion, and, IIRC, the Ultra flows a little better at colder temps than the Platinum does? I assume I am OK running this, but am all ears if people think I purchased the wrong oil?
