I change the oil regularly (every 3,000 miles generally) on my 2.2 petrol estate and I am using approximately 1 pint every 2,000 miles.  The car has now done 102,000 with the first 4 oil changes at the dreadful 20,000 mile interval (ex fleet car).  Despite this the engine runs sweet enough and the oil now stays reasonably clean between changes, I am just wondering if the oil consumption is a bit excessive.

It does sound quite excessive unfortunately

My old t5 with 288k (ex plod) never needed a top up.

Are you sure it isn't a small leak somewhere? Does the exhaust smoke?

There is no sign of any smoke from the exhaust and the car still feels quite pokey for an automatic 4 pot even with a heavy load on.  Wonder if the valve seals are on the way out as I had an old CVH Sierra years ago and a new set of valve seals cured oil burning on that, dead easy job too with the correct tool!

As far as I can see there are no oil leaks.  I replaced the cam cover gasket with a genuine Vauxhall one just after I bought the car and the engine still looks very clean with no drips on the garage floor.
