Has this been covered before?

Has anyone use this product to flush their engines before oil change?
I've read many good reviews on it, I am considering doing this on my next oil change

if you are regular on your oil changes it will be snake oil.. if you have sludge and other bulky contaminates it could be a potential nightmare for your oil system.. in most cases with "newer" cars when properly maintained you will not need a flush.

Agreed. I change my oil every 5k.

+2, run away from that.

agreed

I agree with all your statement, I also changed my oil every 5K miles.
But does it hurt to use Liqui Moly Engine flush once in a while,
I've read many reviews claim engine run smoother after the flush.
Lately at 101K miles, I notice engine idles very loud.

It would not hurt.... But you would probably waste your time.... Loud idle is probably injector related or cbu

My car has a loud idle right now and I am contributing it to cbu
