Electric fuel pumps to pre-lube engine before a cold start?
It is said that most of the engine wear comes from cold starts when the oil is in the pan and the metal parts grind themselves dry.
It is also said that many NY yellow cab engines lasted many thousands of miles because they only had one cold start per day.
Also Formula 1 engines need oil and coolant to be pre-warmed and pre-pumped before starting otherwise the engine will grind so badly it will be ruined.
I remember some electric pre-lube oil pumps were sold at JC Whitney years ago.
Are they worth it?
If OEM automakers were to adopt them, Would they allow closer engine tolerances thus improving engine efficiency while reducing emissions?
