  1. Yep, just got off the phone with my mechanic and he told me the same thing. Lol
  2. So, @riverbanks, I saw that you mentioned that my truck is finnicky. I think you're right. Fueled up at one of my preferred gas stations last week and right aways my CEL came on. I'm not engine savvy at all, but would this be an indication that by o2's may need replacing?
  3. I've thought about trading in for a diesel, but I really don't want to go through another 7 years of truck payments. Even if I would cut my fuel costs in half it would take many years to make up for the extra $40,000.00 or so that I pay out on a diesel.
  4. No, my CEL isn't on. The only time it comes on is when I use bad gas. And I know which gas stations to stay away from. Even when I use this stations' premium fuel my CEL comes on.
  5. Yeah I definitely intend to do a catback, and thanks for all the advice guys. I'll be checking a few things out.
  6. That's decent economy. My crew cab empty, not towing gets around 18L/100kms.
  7. Has anyone tried an exhaust system? I've researched and found out don't do anything with the exhaust except maybe a catback. Which will only give you better sound. Would anyone agree with this?
  8. I have almost 90,000 miles on it. I've run a few tanks of high octane fuel through it with no better results. I've come to accept that I'm stuck with a gas guzzler.
  9. Oh it's definitely worse in winter. Those were my summer numbers I posted. Winter numbers are high 30's. I've considered a ½ ton but I'm worried about how long a ½ ton would last towing something 95% of its life. Never the less, something to consider all the same. Thanks for the input.
  10. Hey everybody. So I've owned a 2013 2500hd 6.0 for around 5½ years from new. I tow a cargo trailer everyday with 6 ladders on the ladder racks which creates a lot of wind resistance, and right from the get go the fuel economy has been terrible, 28L/100km(8 mpg). On top of that it's been getting worse year to year, and I also feel like it's lost some power as well. What would be the best way to improve fuel economy? Should I do something to increase the power? Or would that give me even worse economy? Please help.
