Theoretically in a properly maintained engine most of the wear happens during startup as oil fills the passages.
We have a new Mazda3 Carbon Hatchback that we want drive for a very long time.
We just found out that on pre-start up if both the brake and the accelerator pedals are fully depressed, the engine will turn over pumping oil but not starting.
Is the engine not starting because the fuel is withheld, or because the ignition spark is withheld while flooding the cylinder walls with gasoline?
In either case releasing the accelerator pedal will result in immediate engine starting,
In the first case allowing full oil circulation before fuel introduction could be quite beneficial.
In the second case having excess fuel on the cylinder walls and in the crankcase would be very bad.
Can anyone verify if the fuel is cut off,

 

No one is going to go to the trouble to carefully and methodically do that procedure to attempt the Guinness book of record of having and engine go a million miles from a street driven what should be calorized as a daily driver.

At some point the ridicules gets posted....

If your dry store a vehcle there are things you can do to preserve and reduce the effect of its environment location of storage to reduce the chances of a prestart engine damage. But then there is also a very carefully thought-out service to perform on an engine after a long storage period to reduce the chances of engine dames. But to reduce the chances of tiny amount of engine wear but performing a startup procedure every time to start the engine which is what would be needed to reduce the very low % of possible engine wear is ridicules. And it not the first time it has been posted on a vehcle forum on many platforms.

 

Wrong. Engine oil is thick film lubrication and requires speed for the molecules to wedge between moving parts. Even though your method may produce oil pressure it's in the danger zone for lubrication.
