Default 2nd gen 3.5 ecoboost, long crank on cold start??

when I first start my truck up in the morning it seems like it takes more cranks than it should to fire up. its not terrible all the time but today seemed to be getting worse. anyone else notice this? don't notice it at all if the truck has been restarted within 3-4 hours. only on an overnight cold start.

I needed to start my truck the other day when we were in -40 weather. I was unable to plug it in where I was parked. I used the "flood clear" method, of holding the accelerator pedal to the floor, & cranked it over for a while to try to build some oil pressure before starting. I cranked a few cycles this way, until it seemed that my battery was getting weak, then removed my foot from the gas pedal to allow it to start.
Oil pressure gauge was up immediately. I had a lot of cranking power I thought. I am sure it would have fired up with out an issue, but thought it might get some oil circulating through the engine before ignition.
I also do this after completing an oil change, to prime the system before ignition too.

I like to park in my garage when I am at home but was forced to park at a location where I couldn't reach the outlet with my 30 foot cord.

Iíve noticed mine getting a bit slower to start hot or cold. Like 3 seconds vs 2. Turn over rpm seems fine and no change.
Havenít noticed definitively if gas grade makes a difference, but have my suspicion it may be slower with 92 vs 87 octane?? (which sorta makes sense)

sounds normal to me...but if you think its not right

take it to the dealer and let them deal with it, make sure you let it sit there overnight
