Why would it being on tickover not push oil around same as driving it. I can see any reason that being sat on tickover for 2-3 mins does anything different in terms of getting the oil up to temp and round the engine any less or more than driving it off? If the oil is moving round the engine then the oil is moving round the engine, be it when driving at 3k rpm down the road, or at 1200rpm sitting on the drive the oil is still being pumped round by the fact the engine is running (surely the pressure in the system just builds a touch slower than if your driving, but if the revs are lower anyway the slightly slower increase in oil pressure will be offset by the lower engine speed causing less wear anyhow??? Wont it???).
I don't know enough to argue the point. All I know is its bad to rev above 3k until the oil is nice and warm/fluid. My choice for ease of things is to pop 30 feet away and leave the car ticking over for a minute or 2 to let the revs settlle down and the fueling to sort itself out before setting off at a nice gentle pace and revs before nailing it a few miles later.
I have done this in every car i have owned and I have had none that have suffered major engine/gearbox (if it has shared oil like on the classic mini) failures at low milages. Having taken many classic engines apart and several others like Rover V8s I have never seen any sign of premature wear on the engine.
I will post 1 thing up that might make a difference if the whole start from cold idle/don't idle arguement. I don't leave my cars out in the winter. They are stored in an insulated garage, so that could make a big difference in the initial thickness/temp of the oil in the car before start-up, thus meaning its at a consistency thats fluid enough to get round the engine fast enough when idling?! |
