New engine

[jim172mk1]

Got my car back today after cambelt snapped and Renault replaced the engine with a new one. Bloke at the workshop advised me to run the engine in for 2500 miles. As i did not buy the car new can someone who did let me know how far they ran the engine in before driving properly again.



Killing me not going over 4000 rpm.

i thought it was 1k?

altho never had a new car so its just an educated guess

Yer I am running my 16v turbo in for about 1000 to 1500 miles on Mineral oil. Thats all you need to do.

take it to 600 and rag it from there.....

Think therea a lot of debate on this one..

Some 172 drivers advise 1000 miles before you redline it, though I think others have ragged it sraight from new, with no ill effects.

Me - Id take it easy for at least 500.

I think the manual says 625 miles at no more than 3.5k revs. As long as you follow that Im sure youll be just fine (and so will the engine!)

I should think you could run it in at 3-4k rpm for 500-1000 miles on running-in oil (i.e. doesnt contain anti-wear additives) and then it will fly forever after that with some Magnatec 5W-40 in there.
