I have always had some engine oil consumption. No leaks (beige carpet on garage floor, under engine), no sign of smoking, no problems with emission tests. It is well within the 1 litre per 625 miles than Honda says is acceptable.
I have used 5w-30 since purchasing the car, but the last couple of times I topping up with 10w-40. Now, I find that I am not using any oil at all.
Any thoughts?
