Prolonged Idle Periods

[AL427SBF]

I've read several recommendations on idling etiquette, and some from very reputable performance motor builders. What has been said is that it's not advisable to let the motor sit and idle for extended periods of time, give it a quick rev once in a while. Interestingly, with that sage advice comes no explanation why, just do it. I'm thinking has to be oil pressure, need to keep the oil circulating for a lot of reasons, particularly on hot days in stop'n go traffic. Don't know about the rest of you, but there are times when I'm not looking for attention with repeated quick revs at a stop, sometimes that's perceived as an invitation for a 1 block blitz to the next red light, no thanks. There are some electric aircraft oil pumps out there that are reliable, small, light weight and give you 50 psi steady state pressure at the flip of a switch. Just thinking that would be an option if oil pressure is the only concern with extended idle periods.
