Rep: 64 S D will become famous soon enough

I run Pennzoil full synthetic 10-30 in my jeep with 177k miles on the odo. My dad runs Quaker State HorsePower full synthetic 10-30 in his truck at 235k miles on the odo. My dad regularly runs a year or so and 8-10k miles before changing his oil too, so I'm sure the stuff works pretty well.

We run regular Pennzoil 10-30 dino oil in our fifth avenue and other vehicles.
Simplify, then add lightness
