Engine flush

Hi guys,
My car a 525i, 2002 with 210000km is consuming 1qt of oil every 1000km, my indy is suggesting an engine flush with an oil change. I am hesitant, any opinions ?
Thanks in advance

How old is your crankcase ventilation (CCV) system?

I'd be a bit leery of engine flushes on any car. I read that it's possible to damage seals or have clumps of sludge clog vital passageways....

Is your engine suffering from sludge deposits? I'm curious why the indy is suggesting a flush?

How long has it been using this much oil? Or have you just noticed it?

The M54 is a known oil burner, but this much seems a bit excessive for the kms on the odo.

Do you drive a lot of short trips during the week?

Yes, my daily average trip is about 15km X2; I agree this may qualify to be a short trip and I keep the engines RPM around 3000 since its a manual tranny.
As to my indies suspicion as far as the sludge build-up is concerned, I haven't got a clue, I think he is sooting in the dark.
Is there a way to check sludge build up in the engine ?

Most obvious point is to remove the oil filler cap. Shine a strong light down the hole. If you see gobs of black, gray/brown sludge, it's time to do something.

A successful treatment is to use Rislone. One or two can loosen up the oil rings, and dissolve the sludge. Even if the engine appears to be clean, a treatment couldn't hoit, like chicken soup.

I would stay away from engine flushes too. A neighbor had one done at a oil change place and the engine smoked worse after wards. Ended up getting rid of the 07 Toyota van with 100,000 miles on it.
I would do a high quality injector cleaner-valve cleaner first. Then a couple of frequent oil changes.
If your valve cover gasket hasn't been changed in a while, now would be a good time to take a peek at the valve train and see if there's any sludge up there.

Thanks for the replies. I'll check by removing the oil filler cap the inside of the hole and take it from there.
