[QUOTE="absidian, post: 216345, member: 4356"] I'll happily throw a spanner into the works here about engine warm-up and idling... the "time spent idling at lower temperature" versus "driving below 2.5k immediately" is not entirely correct either. There isn't a perfect answer, there is only the best compromise to choose from. The main argument here is in [b]engine load[/b], more specifically load on the crankshaft bearings. At idle, there is minimal load/stress, but when you drive you are loading it greatly whilst cold. So it's not just getting the temperature up, but what you do with the engine in getting there. In today's modern engines, the cylinder wall selling-point that you see in adverts is not as important as the crankshaft bearings in terms of oil. Look at highly stressed engines or race engines (e.g. M-cars) the bearings are more likely to fail before any cylinder wall issues. Interesting eh? [/QUOTE]
