Please run a test for me.
Remove drain plug and wait 1 minute. Then place a separate catch basin under the hole and wait 14 minutes. Then measure the oil captured in the last catch basin. Report that here on this thread please?
Thank you!
My next F-150 oil change is due in January.
What would your experiment prove? Is not as if you asked for a Blackstone sample of the first oil vs the last oil.
On one hand "experts" say to drain oil hot.
On the other hand you seem to be challenging Ford's instructions to drain for 15 minutes, not just "until it stops dripping."
Is my observation that Ford is making effort to keep oil in the galleys for instant lubrication with start/stop system. That the oil filter needs to be opened first to let air in for the most oil to drain.
