Mentioning Quaker State, my favorite story on that was when I was
working in an independent foreign car shop in Michigan in the `70s.
Two old ladies had identical Honda Civics (in the days when the
water-cooled Civics were fairly new, no parts available, and had,
essentially, throw-away engines). If one had something done to her
car, the other had to do it, as well. One decided that she should
use Quaker State, and the other wasn't to be outdone.
A year or so later, both engines had a valve train and valve cover
full of sludge. In the next years, Quaker State had a widespread
reputation for sludge formation, which they mostly countered with a
massive ad campaign emphasizing reformulation.
Sludge is oil-borne ash, nothing more. Pennsylvania oils have a high
ash content, as do the coal formations in that area.
