My 2011 vogue se with 106000 miles use`s about 1.5 ltres of oil for every 800miles traveled there is no smoke and the engine runs very smooth with no rattles when cold would this be right.

No.

Mine was using a bit of oil. Leaks found at the bottom end of the engine. One on the dipstick tube/sump drain and one on the passenger side turbo.

Since these have been fixed it hasn't used a drop, was services at the same time and that was 4000 miles ago.

Also check the condition of the water in the expansion, and check the oil/water cooler in the V as these can leak oil into the cooling system. There is nothing that can't be fixed with a hammer😜😜
