Ok so it's the cold winter months and i know that a lot of you (my whole family does it) probably start your engines about 5 mins before you set off in order to get some warm air flowing. Plus i always thought this was good for the engine to get some oil going and getting it a bit warmer.
However i was just flicking through my astra care and maintenance book thing that came with the car and it says a couple of times.
"Do not let your engine idle to warm it up, always drive off as soon as possible and allow the engine to warm by travelling at a moderate speed for the first part of the journey"
Or words to that effect. I mean yeah idling the car uses a little bit of fuel before you're even moving but i'd have thought it would only be like 20ps worth or something. Anyone able shed any light on this?
