Run in engine?

Manufacturers usually advise that cars should not be driven hard for the first couple-of-thousand miles to allow moving parts to 'bed-in' - the running-in period. The guy who wrote about his car still being run in at 100,000 miles simply means that his car runs sweetly, is one well-known for long engine life, and that he fully expects it to do another 100,000 miles without trouble.

I would have thought that *any* engine that is looked after as the manufacturers recommend could qualify for 100K easy and 200K probably.

Probably, but then other things outside of the actual engine might fail where people can't justify to fix and so the car's goes in the bin etc.

Saab? old Land Rover?

I was being silly. Do have some sense of proportion, Peter.

As long as it doesn't start pinking.

You weren't the only person who said it though, or did you say it twice? Somebody else (or maybe you) said something about most new cars not being run in until after 100,000 miles.

Years ago, manufacturers used to advise 'running in' for the first couple of thousand miles. Not using maximum revs, allowing the engine to spin without overloading, gradually increasing its workload. This helped running parts to bed in -particularly the pistons, rings and cylinder walls. Treat it harshly during this period and you could end up using a litre of oil every thousand miles due to excessive wear on those parts. (Got this from Homest John) VAG fill their engines with a long life 'running in' oil at the factory. If people read the handbook they would see the instructions about running in and wouldn't be back complaining about excessive oil consumption. You have to work the engines harder and harder over the running in period. It helps to break down the glaze on the finely honed cylinder walls and piston rings. Treat them too gently, nurse them along, don't work them too hard and you could end up using a litre of oil every thousand miles. RTFM as they say. DaveK.

A lot of people now say that it's not needed, but others aren't so sure.

What does pinking sound like?

I said my Montego's got nearly 180,000 on the clock so it's hardly run in yet.

Ah it was Connor lol, "115k is just about run in for alot of engines."

Sounds like Peter getting his knickers in a twist.

What's "lol" about Conor? And do try to spell his name right.

(petermcmillan snipped-for-privacy@yahoo.com) gurgled happily, sounding much like they were saying :

Yes, and?

When I got my Fiesta they said it wasn't really too important any more, just drive normally for the first 1,000 miles. i.e. Don't trash the living crap out of it ;-)

Most engines are run in well before that aren't they?

Well yes I agree with that, but the OP said "engine" specifically.
