At the rear is the oil filter... kind of in line with where the driver sits, under the exhaust manifold. Id check there first.
However. How many miles are you doing in a couple of months? circa 1000 - 1500 ish? that amount of oil consumption sounds about right for a daily driver, on that sort of monthly millage. loads of different factors for oil usage but that's another matter...
If its not used that regularly, the slight drip isn't going to be loosing you that much, and the usage is down to another factor. I found mine improve greatly when I changed to a different brand of oil for example. simple as that.
hope this helps mate. let us know your findings.
