Whenever I read forums on oil changes, I never hear anyone mention the other important thing after changing your oil when it is warm; priming the oil filter. More damage is done to an engine in that first 15 seconds that an engine is started after an oil change. All that fresh oil is sitting in the crankcase, waiting to be drawn into the pump. When that engine is cranked, all the crankshaft journals, all the springs, valves, camshafts and other parts that need to stay lubricated are dry! Those few seconds of dry turning are destroying those bearings. Always remember to take a few minutes to pour oil into the filter first. Since the filter has a back-flow stopper, you need to pour a little, let it fill, pour some more, let it fill, ect. Most filters will take up to a half a quart in them. Since that is done, now oil can get to the pump almost immediately, since the filter is usually the closest thing to the oil pump. When re-installing the filter, turn until you can feel the o-ring touching the filter, then turn it just about 1/8th of a turn more. You don't want the filter too tight. Finally, if the car has a turbocharger, it is important after driving it to let it idle for a minute to give the oil a chance to continue to lube the turbo as the blades slow down. This isn't a problem in a supercharger, because it runs on crankshaft motion.

Good advice. But that doesn't work if your filter is mounted sideways or even further past horizontal.

Letting a turbocharged engine idle for a minute prior to shutdown is simply a waste of fuel in 99% of the cases. That said, if you've been blasting down the highway at high speeds and quickly stop in for a tank of gas, then yes, letting the engine idle for thirty seconds or so is a very good idea.

that's my read on modern turbos...just ignore cool down unless you have just come off a freeway ramp at 80 mph in 100 degree heat...in other words, extreme situations.
