Ours uses a little, but not what I would describe as an oil burner.
Keep the level between the dipstick marks, not right up to the top, as it will use more.
Just back from Scotland, did just under 1500 miles in five days, no issues at all, ran on gas nearly all of the time, which tends to make oil consumption higher. Used about half a litre of oil, but it was over the full mark on the dipstick, due to the 'dipstick' overfilling it!
Shell Helix 10W-40 Fully Synthetic, but only because of the gas, would use semi-synthetic if on Petrol.
