Not knowing where the OP lives, it is difficult to offer an opinion, but I would think it is the recent very cold snap that has caused the increase in consumption. Also very pertinent is how far the trips were. If the ICE does not have a chance of reaching optimum temperature, that would affect the consumption detrimentally.
Lord Voltermore may well be correct. When I worked for Shell Retail Lubricants all manufacturers factory filled with a fairly basic oil to aid engine 'bed in'. (improved technologies may have changed this, of course)
We produced a a very high quality semi-synthetic diesel engine oil and it wasn't long before a well known truck manufacturer contacted me saying that they had received complaints of excessive oil consumption from users of new vehicles. We joined forces with the manufacturer to discover what caused the problem. The result was that the oil was TOO good for initial fill and the bores had 'glazed', causing excessive consumption. They went back to our more basic mineral oil and the problem was solved. Once the engines had bedded in they recommended the semi-synthetic grade and there was no problem.
