Even if you can't fill the filter completely, just saturating the filter element helps a lot!
I do not prefill the oil filter. Never have and won't be doing so in the future.
If the engine has been ran in the near future it has oil in all the parts it needs to be. The term starting an engine DRY is bunk. Oil doesn't just disappear from the bearings. An engine will run for quite a long time (at least a minute or so) before having any problems.
Ya, about burst pressure. You wouldn't need any burst pressure if the oil was sucked through the oil filter. Really???
I do agree the engine has no oil pressure for a few seconds though.
As a mechanic for the last 55 years or so I have made a mistake or two.
Changed the oil on a car and forgot to put the drain plug in. Added all the needed oil, But, it went on the ground under the car. MUST HAVE BEEN DAY DREAMING
Proceeded to start the car, backed it out of the service bay, drove it out onto the street before I noticed the oil pressure was ZERO (no light). Drove it back to the bay to see the problem OOOPPPSSSS !!!! no oil, Put plug back in added oil needed and started it up. Worried Worried about damage. That particular car was in service for at least the next 60,000 mile that I knew of....
Had a race motor blow the filter gasket out more than a quarter mile from the pit. Driver drove to the pit and we changed the motor, Because we thought it would be toast running at 7,000 RPM. NOT TRUE.
After tear down I found everything looked like new. NO damage anywhere. WE actually put it back together with same bearings, rings and just new gaskets. Ran fine and never blew up like we were afraid of.
I could tell more stories but you get my drift. Then again maybe I'm stupid for not doing so.
BUT my luck varies FIXIT
