Does it make sense to create a slight pressure differential within an engine before doing a cold start to move the oil around? Something as simple as a hand pump connected to the oil cap would do the trick. But I don’t know if this would have any benefits?

Probably minimal benefit my guess, a block heater would be what would be advised from my life in ND

There is benefit. But not pressure to the oil cap, that does nothing. A pre oiler, commercially known as a Accumsump, can be used to store a bit of oil under pressure that can be released before starting the engine to reduce wear. There are also electeically driven add on oil pumps that do the same…

[image] Mustangman: Considering most modern engines will run well over 200,000 miles simply with proper maintenance, doesn’t seem worth the trouble or cost. You beat me to it! A modern engine that is well-maintained can be expected to go 200k miles–or more–with no need for internal repairs. …

I’ve read that while most engine wear occurs at startup it does not mean those first few seconds for oil pressure to build. “Startup” means the period before the engine warms up. The pistons and cylinders expand at different rates with the rising temperature. The mismatch plays havoc with clearan…

Why not just crank motor with ign/fuel off?

The proper multi viscosity oil greatly reduces the wear at cold start up. Possibly more than pre-lubing. Pumping up oil pressure to a cold, still engine will not lubricate the cylinder walls, piston pins, and various timing components while the freer flowing modern multi viscosity oils can quickly b…

Click and Clack went down this road 30 years ago… [image] The "pre-luber"...to buy or not to buy? I've heard that someone makes a device that lubricates the engine with a separate oil pump before the car is started They claim that it will save significant wear and tear on the engine Have …

They make pre-lubers for turbo engines.

These supply pressurized oil to the turbo prior to starting the engine, and supply pressurized oil to the turbo after shutting down the engine to cool down the bearings.
