I think the oil cooler is built to withstand serious oil pressure too, and not just 100 PSI

I once pushed the warm up because I was late on the 210, it’s oil cooler on the 520 was bolted directly to the engine, it blew its gasket, blew as in just a small leak.

I do believe coolers can take pressure in the hundreds, and I think especially straight grade cold oil can get there without trying too hard.

15W-50 Aeroshell as it’s a 15W oil isn’t going to go nearly as high pressure wise, but suppose in very cold weather even it can get like grease.
