Okay, I’ll bite. Working on engines all day, you get a real feel for what they like and don’t like. My “if you know, you know” thing is all about smoothness, especially on a cold start. Most folks just fire it up and go, but giving the car just thirty seconds to let the oil circulate before you even touch the throttle makes a world of difference for long-term wear. It’s not about revving it high, just letting everything settle. Anyone else have a tiny habit like that that pays off big down the road?
