Hi everyone, first time posting. I've noticed since I purchased my 2015 5.3l chevy suburban that the average miles per gallon is low. I dont rev my engine, I always keep the screen up to monitor my fuel economy as i drive. I seem to always avg 15-16mpg road and 17-18hwy....
Does this seem normal???
I put in regular unleaded from krogers and costco.
I have 43k miles on my vehicle
Live in an area without high terrain. Regular suburbia.
Something just does not seem right.
Any input, help, modifications, changes required to improve?
- yours truly
A concerned chevy owner!
Thank you!!!!
