Not to much i check it weekly and dont have to regularly top it up but no i couldnt give you an exact amount lol, i had an RX8 before this and that used oil like it was going out of date soon XD
It only smokes when at stand still or pulling off in first and its only a poof not like a big diesel cloud. I can be in 3rd doing lets say 3k rpm then nail it change at 5k and nail it again but no smoke ( it was a test i dont usually drive like this)
just got a compression tester so i will do that this weekend see what i find.
Thanks for the correction NeilP lol
