I did a good bit of wrenching for a couple of dealers and a local independent in the mid 70's.
We found that local driven short distance engines had more sludge buildup than ones belonging to those that drove longer distances.
At that time engines with Valvoline would have a dry ashy sludge that at times would completely fill the valve cover and lifter valley areas.
Engines that ran Pennzoil had a gooey tar like sludge.
Engines that ran Gulf oil had a shiny waxy sludge that was hard to clean off of the valve covers.
Quaker State wasn't a popular brand in our area at that time so I can't comment on it.
Personally I used Chevron oil in my engines back then, it would leave a black oily sludge but didn't seem to build up as much as some of the other brands. but then it may have been the way I drove.
Todays engines run much hotter and are driven longer distances, one doesn't see sludge buildup like we saw back then, I'm sure improvements in oil has also helped reduce sludge.
