Hi, I am Daniel
are you with me?>
There certainly is things that will burn off and give you a odd smell. Cadillac has
battled oil consumption for a while and the new 3.6 hasnt any changes in it to reduce
issues. There are some that do very well. And I believe them to be very well
maintained fluid systems. But I cant promise the 2012 will be better than the 2011. I
would get extended warranty if you do get it.
I understand your frustration. The answer to the causes is a bad valve train design that works against its self fromthe start. There are actually two reasons and one or both may apply sometimes. and the rings dont seat. It is amazing to me still that 1 quart of oil is acceptable for 500 but thats what they do say. And they need to stop building engines if they cant do it any better than that. If you dont want to be disappointed I wouldnt buy one.
