I don't think Quaker State is necessarily worse than Valvoline. And if it's made with paraffin, I wouldn't necessarily blame that for sludge, based on one engine. How was the engine maintained? API specs (SH, CH-4, etc.) all have requirements for detergency, dispersancy, etc. Get the latest API spec (S=gas, C=diesel) and do proper, timely oil changes. By the way, Mobil Delvac 1 is some amazing stuff for diesels, I'm told. Synthetics can tend to permeate (leak) a little more than conventionals, but make up for it on the inside where they keep things a lot cleaner. That'll be 2 cents.
