Honestly, id much rather find that then a motor that was drained and sat on a concrete floof for 25 years.
That all will clean up nice.
STOP POTATO HATE!

You would be surprised how often I see this, and on fairly new cars.

My aunt had a 69 Olds Cutlass she insisted got Quaker State oil changes ever 6,000 miles. Around 50,000 I had to replace all the rocker stands. The motor was so sledged up, the rockers left an imprint in the crud stuck to the inside of the covers. I had to do the whole deal again at around 70,000. I finally convinced her she needed to quit using Quaker State, and she needed to change her oil at 2,000 miles instead of 6,000 miles. After following my advice, she did get over 100K miles out of that poor Olds before she traded it on something else. Gene

Had a '72 318 with a spun rod bearing years ago that, when I pulled the intake, I was looking at an impression of the bottom of the intake. It looked like it had a valley pan the way B/RB engines do but it was in fact solid sludge. I'm not 100% sure but I think the engine still had it's original oil filter on it and this was around '91.........

Saw that a lot in the 70s with regular oil changes of quaker state and z7 pennsoil. Oldsmobiles were the worst, cylinder head drains would plug. We used to pour 3 gallons of kerosene in them, run them, and change the oil to valvoline or texaco, never a problem after that. Ive seen this exact same thing happen to engines even with proper oil changes . The company I used to work at back in the 80s used nothing but Valvoline, And after pulling the valve covers on one truck and I couldn't see the rockers arms, Ive never used Valvoline since

All my stuff had valvoline or phillips 66 and looked like new with 3000 mile oil changes. Cold weather state. Who knows?

Kerosene That sure would LOOSEN IT UP but then it drops into pan THEN blocks the pickup Never a problem, scrape out what you could, jack the front up on the rack to about a 30 degree angle, let it drain overnight, chunks came out. Never lost a motor, one olds went another 100,000 after that. 318s had an issue with the plate on the bottom of the intake, oil would coke on the intake after the heat riser stuck shut. I saw one so bad that you could not see the cam and the plate and 2 rivets were laying in the motor. Same deal, clean, kerosene and a few oil changes and it never quit till it went to the junkyard.

I remember rebuilding many cylinder heads that came in the shop that looked like they still had a valve cover on them. The mechanic had to dig out a hole to find the head bolt.

I wouldn't doubt that some oils would tend to leave more deposits than some others. But my personal experience is that the vehicle's daily operation is much more of an factor. For instance, I began my Mopar experience by using the engines from retired police cars. Never have I pulled an ex-squad down that had those kind of deposits. And all of them had a ton of miles. But they had spent nearly all of their operational time at full operating temp. But I have been into many low mileage engines with that kind of sludge. Most of them were primarily driven around town, running errands, stop and go from home to the store and back without the opportunity to fully warm up. I have read that when oils are slightly heated and then allowed to cool, that the parafins in them tend to separate out and deposit. While getting the oil up to operating temp and kept that way for a sufficient amount of time, keeps the parafins suspended in the oil. Modern oils resist that better than earlier oils, but sludging is still possible. And then engine design plays a role too. Think the 2.7 from 20 years ago. In other words, there are a lot of factors beyond simply the brand of oil that plays a role in engine deposits. And although I haven't done it for 40 years or so, we used to flush engines with kerosene. I was actually taught it in auto mechanics class in high school.

Makes sense, seems the people that had us change their oil never had a problem, same brand oil all the time. I wonder if using various brands would maybe cause the problem. They used to sell motor flush, but kerosene just flat worked every time.
