1981 Pheonix....I remember those cars well. At one of the houses I grew up in, our next-door neighbour had a 1980-81 Pheonix...2-tone blue, 5-door hatch. He was really careful with maintenence, and washed it a lot. It was always very clean, I thought it was a nice car.
Anyway, more on-topic, at the WM TLE I worked at, all the 'old timers' hated the Pennzoil we pumped into cars. One said it was 'watery junk' that didn't help an engine live. They all used Valvoline. I've used mostly Pennzoil in my cars over the years, just b/c I worked at WM for years, and could get my oil changed while I worked, and it was the cheapest change going. Never had a problem with it.....
