Electric Oil pump
It only seems like driving an oil pump is easy, in reality driving an oil pump is very hard. The biggest issue is the viscosity of the oil especially when it's cold. The second issue is, the oil pump is the most critical component of the engine. A bad oil pump leads to engine failure 100% of the time. A bad fan or a bad electric water pump or a bad fuel pump don't lead to immediate engine failure. A mechanically driven oil pump is guaranteed to spin when the engine is spinning. The ware effects of dry engine starts are exaggerated for daily drivers. Overnight the critical components retain enough oil to allow the engine to build oil pressure before engine damage occurs. When engines sit for weeks at a time a shortening of life from a dry start may occur but it is hard to quantify. I think a good compromise might be to have an electric pump for priming but a mechanical pump for general engine operation.

2003 Hyundai Santa Fe will start then die. Then it will not start. After pumping the accelerator or holding on the floor and returning later it will start. Nothing codes out. This happens probably 15% of the time. Any ideas?

A friend has an older Miata that was improperly stored for at least three years. Most of the time, it was not garaged. The gas is old, the battery is dead, it has not been started. It was probably parked without an oil change. He is looking to do the minimum to get this sellable, so the primary concern is the initial startup and the brakes. What would be recommended , especially regarding that first engine startup?

I’ve asked a few mechanics and DIYers this question and so far no consensus. Let’s say you’re 1000 miles away from next SCHEDULED oil change, and you’re about to leave on a 2000 mile road trip. Would you choose to change your oil 1000 miles early before the trip, or 1000 miles late after the trip?
