I just now got my oil changed with Pennzoil 5W30 (10,750 mile maintenance).
Afterwords on the ride back I couldn't tell that my oil had been changed at all
(car drove just as if I didn't get an oil change).
With my 7,500 mile maintenance I did get Nissan Ester Engine Oil with my oil
change (as with my 3750 mile maintenance). I *was* surprised that I could
tell the difference after the oil change. The felt renewed and ran much more
silky smooth when accelerating and shifting.
Based on this, I'll probably spring for the extra $60 to get the Nissan Ester
Engine Oil.
