Not in the 272 but it's the getting up to speed. Car will changed around 2-3000 revs working up to speed and if you are going up hill the load on the car will make the box drop a few cogs and joining moving traffic, sometimes you got to give it a boot. As I said there's a million variables to oil consumption. Not warming up is just one of them. The first 1000miles(break in period) is pretty critical as well as that will determine its future.
