wifey said the same thing about her 01 HOe. it has been cooler lately so... but next oil change ill put mobil 1 in both. hopefully that helps. her truck has like 60,000 or so..well see.

i use mobil 1 and still get it. turn up the radio and let it idle a good 30 secs before you go.

Started using Royal Purple and it cut back on it dramtically, all of my buddies with the 5.3 and even me sometimes when its real cold have it so no worries

It's was in the low 30's for a few days so I have to let the truck warm up to defrost the window anyway. When I get out of work and it's still only in the 40's I hear it for about 20 sec when i'm driving. 80kmi on the clock.

I've used Royal Purple since day one and still have the same problem. GM put out a TSB saying the piston to cylinder head is very tight and carbon forms on the piston. After you run it for a bit the carbon is broken up and everything if fine until it cools down again. They say if you get a fuel injection service done periodically it will quit. Most repiar shops should be able to do this. They use a tool that vaporizes a cleaner and sprays it into the intake while it's running.

Try the "Engine Flushing" a couple of changes...don't be shy.

U'll thank me latter...just related to the noisy morning start with a kind of lifter uncharged sound.

Not the piston Slap from the Gen III, that has no cure hahahahaha
