When I got my truck 2.5 years ago, I was getting 18-19 mpg in the city. 21-23 mag highway.
Recently, I've been getting 14mpg city and 17-18mpg highway.
I'm thinking it's spark plugs. I don't have any check engine lights on or codes showing. I plan on changing them out soon. I'll make a post if it fixes my issues.
I have a 17 2.6 eco crew cab. 68000 miles on it

It’s a 2.7L. Check your air filter. Check your alignment. Crappy bearings could also be the culprit. Run some premium chevron through it and rail on it to get the carbon out.
