I think it's like a pinging noise when it's under load. However, with MAF sensor cleaned, that noise went away under load. I think I might here it sometimes, but not nearly as bad as before.

Piston slap won't be fixed with any cleaners, flushes, or additives.
Yes I understand. I can't be sure if Kreen did anything to the noise because I have never put mobil 1 in this car, so there's no reference for comparison. Filter wasn't the same either (got a bosch almost free with coupon before changing to purolator classic now). So I guess the only thing I can do to see if Kreen did anything is by checking if the oil burning problem is reduced in any way.
Kreen keeps cleaning after oil change? Is it with the residual kreen in the crankcase? I noticed that the oil burned quite a bit faster, dropping to half way on the dipstick within the 1200 miles I drove with Kreen. I assume it either was thinner and thus got past the rings more readily to be burned, or that it simply evaporated. It'd surprise me a little that there's still cleaning effect after flushing, but all the better!
The thing is: why didn't I get a really black and sooty drain? The oil was pretty clear even with the pretty high dose of kreen+pistonsoak. Does it mean it didn't work all that well, or the engine is actually pretty clean (i doubt it unless MMO really did wonders).
Thanks guys.
Pinging under load is different from an engine knock. I have two owners manuals for older vehicles which state light pinging under load is normal.
I found in my test mule Kreen kept cleaning after the oil was changed. I don't think it was the residual Kreen, I think it was just more junk that was softened up coming out.
As far as why the oil didn't come out sooty black. It depends, sometimes it comes out deep brown, sometimes it comes out the same as it always does. Maybe you had nothing out of the ordinary. Maybe the MMO did the cleaning. Maybe you had nothing to clean. My point is some people never establish their engine is dirty, and clean it. You can't clean something that's not dirty. Others use different products and have no idea which product to credit with the success or failure to clean, or for different sounds coming from the engine. Others are quick to point fingers of blame just to stir the pot. I try and ignore them.
