Many Folks when start car in the morning, and most of them either push the accelerator again & again to make it warm 'or' will start driving after just couple of seconds from start. Both of these them bring bad results for Engines, but later.
Ideology for increasing RPMs (pushing the accelerator) is, to let the engine oil quickly circulate and lubricate each & every part of the engine. But these folk don't know that if they will NOT Push the accelerator so hard or again & again, even then the oil will lubricate each & every part of the engine. But it depends which kind of oils is being used.
Ok one more time,
....these folk don't know that if they will NOT Push the accelerator so hard or again & again, even then the oil will lubricate each & every part of the engine. BUT IT DEPENDS WHICH KIND OF OILS IS BEING USED.
Because every engine oil has its specific time to reach every part of engine & lubricate it, since cold start.
(again expecting many -ve comments, as usual, but lets see.)
