My local Walmart had Pennzoil Ultra 5w30 back towards the end of last fall. I figured I would try it in my 99 Camry 5S. I noticed the car ran slightly quieter in comparison to Mobil 1 Extended Performance. However, the biggest difference was how light the oil was on the dipstick. After 2200 miles I had the valve cover gasket and numerous seals replaced. My mechanic went ahead and changed the oil, which wasn't a bad idea. But, I would have really liked to have kept that oil in there since I can't seem to find it anywhere. I did find the 1quart bottles of SRT 0-40 at Auto Zone for $2. That went into another car that consumes oil. I beat myself up for not buying some 5quart jugs.
