i smelled it as it was draining into the oil change pan and the oil that was on my hands smelled that way. And the oil oil smelled burnt not the new oil after it was put in.

Ok. So last year i got a catalog from JC Whitney. It has a 2003 GMC 2500HD Duramax on the front cover. I have the same truck and want the tires that they have on that truck. However i called JC Whitney and they can't help. I hope someone here has seen the cataolg and can help.
