Oil burning?

[whacked]

I was just wondering if anybody has trouble with there truck burning oil? I have a GMC 04 and all of a sudden it started burning oil and no leaks. I have about 4000 miles on the oil change and it was down 2 quarts. I am using 15W40 amsoil and never had any trouble before. I just noticed it today and didn't get a chance to look it over yet. Next week when I get a chance to look at it I will check out a few things I was just wondering if anybody would have a good starting point. I almost forgot it has 57000 miles on it and it acting out of the ordinary.

Thanks in advance Eric

Not me. I have over 10k on my Amsoil 15w40 with 50% to 60% towing and I am down just a bit over half on the dip stick. This is on my 05. I have never done that well with Rotella T synthetic or Mobile Synthetic. Sounds like something is up.
