Engines with prelube(oil pumped in b 4 starting)will last a very very very long time.I have 03 excursion(my global warming statement).It sits long periods of time.Turn the key...oil gets pumped to vital parts,then it starts.
I have a Pre-Luber, fender mounted electric oil pump, hooked up to a toggle switch. When I get into my van, I turn on the pump, and watch the oil pressure build. When the pressure is in the normal running range, I start the engine. I believe it is a tremendous aid, especially in a vehicle that is used infrequently.
It is also helpful after a long trip during very hot weather. I shut the engine off, and flip the Pre-Luber on and circulate oil through the engine to cool it.
