Hello I have 2002 GMC Denali pickup with a 6.0 engine. I expereince some noise at start up, but I also have noise @ about 1200-1300 RPM when the engine is warmed up. I have tried M1 5-30 and PP 5-30, but the noise is still present. The engine still runs strong, but I do not like hearing the engine noise. Do you think a 10-40 or high mileage oil would help eliminate the noise?

Have you tried different oil filters yet?
Yes, I currently have a K & N filter on.
Unfortuneatly we have been seeing a lot of cam and roller lifter problems with the LS engines.
Is the noise something to worry about? How do I address the issue if it is causing problems?
when it come to something like this, Castrol German 0w30 quiet down the noise. many ls have this problem and this oil quiet it down.
I would try valvoline high mileage 10/40 semi syn

Have you been getting metal on the oil drainplug magnet? They also have piston slap noise. The heads have to come off to replace the lifters. Since the replacement engines have a reasonable price and given your mileage I would probably just ride it out. If the mileage was less I would repair what you have and that may be an option for you, it just depends on how you feel about it and if you can get someone to do it for under say $1900.

I am not the original owner, but I believe the truck was serviced well. My guess is the oil was changed between 3 and 5 thousand miles.

No metal shavings. I guess I will just keep trying different oil and keep my fingers crossed......Thank you for your input.

I have read that these engines are noisy at start up, but last for a long time. Mine is not that noisy @ start up, but makes some noise @ low RPM. I am hoping that a different oil will help.

I`d try a 10W40 dino like Pennzoil or Valvoline.
+1 i would try a xW-40.
I'd be putting Valvoline 10W-40 in that truck so fast it would make its hood spin.
