3 weeks and working!

Reviewed By Will A (HATTIESBURG, MS) Reviewed for a 2007 GMC Sierra —1/2/2017 9:05 PM

91K miles on 07 New Body GMC Sierra. I have used the Range for 3 weeks and 1K miles. Product works good so far. It does exactly as stated in description. 16.5 mpg. Have not had to add oil. Been adding 1qt every 1K miles. I have noticed a little rough idling recently. Not sure it's from the Range or not. Didn't notice before I installed. I would recommend ordering.
