Just wondered if I can get some advice, please. I have had my 64 plate 2.2 I-DTEC Auto for around 4 months now and as part of my weekly maintenance check, I have been keeping an eye on all the fluid levels. On checking today I note that the car has used approximately half the tank of oil in just over 3k miles since I bought it. Can is used mostly on motorways and never thrashed though I do regular (weekly) runs of 60 and 90 mile return trips. I bought that car with 20300 miles on and it's just touched 24k miles. I am aware that some cars use a little oil between services but that to me seems a lot. If I fast forward 3 months until its next service then it will have used the entire tank in little over 6k miles - I have never had that on any car I have owned before and I have owned many cars and all diesels. There are no leaks. Is this normal or something to be concerned about?
