Hi all,

(don't sound bad) had I look in here and I find horror story's :0

I change the oil and filter every 5k, outside of that nothing special.

Thats up to you and several people deride me for doing so but others on here, who really do know their stuff agree its the single biggest thing you can do to safeguard your engine.

Regular oil changes will make very little difference if any to inlet coking.

However the THP in both the DS3 and MINI has a famous/infamous timing chain as well. The best way to keep a timing chain happy is make sure it's well lubricated, the best way to do that is clean, fresh oil and the best way to do that is regular oil changes. It also can't hurt the turbo bearings either, your car at the end of the day people mocking you aren't going to pay your garage bills if it goes bang and aren't paying for your oil changes either.

Nobody said it would, the OP asked "how much do you guy services your thp ?", my answer was "I change the oil and filter every 5k, outside of that nothing special".
