Says the guy who has driven the snot out of his Porsche Boxster. Now with 128K miles on it and no major repairs EVER. Oil changed according to the manufacturer recommendations, and routine maintenance done by me. So I’ve never treated mine “badly” I guess. Although I have treated that skinny pedal on the right badly at times.
For purposes of this discussion, as soon as my oil pressure idiot light goes, it’s in gear and rolling out of the garage. Been doing that for 128K miles.
I said “more than to” up there. I know there are still genuine aficionados in the mix; they are among the first to pull up alongside and grin when I’m driving my summer car.
Point being, even the upper-tier Porkies are engineered to get in and drive away, day after day. (Maybe not the uber-exotics, and on those, you really should check the tires at least every five years. RIP, Paul Walker…)
The old two cycle detroit diesels all had blowers on them, a gear driven supercharger. This was in the 1970’s and a warm up period was recomended. Not so much to warm op the engine to operating temps but to make sure the oil had reached the blower. A lot of the early supercharged cars were using detroit diesel blowers. This may be where it started.
Oil can and will drain down from passages as parts wear. You can hear this when an engine is started and the hydraulic lifters collapse causing the followers to rattle.
Some older engines used gravity feed to lubricate things like cams.
