If you say so.

and my 6.2 gm is better on fuel than my 5.3 was.
For 2012...

The 5.3 is rated at 15/21/17.
The 6.2 is rated at 13/18/14.

Pretty significant difference in ratings for your 6.2 to do better than your 5.3....assuming they were about the same year truck. However, if you had say a 2005 5.3, that one is rated at 14/19/16....very similar to a 2012 6.2. Then again, kinda silly to compare a 2005 5.3 to a 2012 6.2, but I digress.
