Ive always heard that idling isnt good for a car engine, yet there are UOA on here from vehicles that idle and they are decent. Are the UOA just not picking up on excess engine wear or is idling really not that bad? I know at idle you have low oil pressure, would a thinner or thicker oil aid in regards to this? Would a thin oil aid in easier pumpability and make its way to the cams and valves at the top, or would thicker be better. Just wondering, Ive been doing more idling in my car lately and it got me thinking, how bad is it really? Also, is your engine properly cooled at idle, and what parts of the engine suffer the most from idling? Thanks for any and all help!
