Change it now ASAP.
Factory oils not good most of the stuff from the bult comes out innthe first few miles of running.
Running is should be done hard anyway.
I don't think so otherwise it wouldn't be called running it in and it wouldn't say in the manual to keep under 3 1/2 for 625 miles. If you want to ask Renault to see whether they'll change their running in term to thraping it in go ahead lol :lolup:
After you've ran it in and gradualy built the revs up it's best to keep driving it at the top of the rev counter for a bit to loosen it up (when it's not cold). If you don't drive it hard after you've fully ran it in it can be just as bad as not running it in properly, agreed, because the engine needs to loosen up (especialy sport engines becuase their designed for going fast so if you don't loosen it up after you've ran it in it will never be as quick as it should be) but you need to run it in properly first.
Renaultsport engines are partly run in before they go into the cars so you shouldn't get as much sh*t in the oil as some cars.
I've not changed my oil becuause if there is a problem because I've not changed my oil Renault should fix it under warrenty as there the ones that have told me and stated it in the handbook not to bother until the 12000 mile service. I've not heard of anyone having a problem because they've not changed the oil in a Renaultsport car (correct me if I'm wrong though).
If you really do want to change the oil I'd ask Renault first though because there very funny about people doing things to cars under warrenty (I know it sounds silly as it's only changing the oil but it's worth a phone call I'd say).
