ANY modification that make your truck look or sound better will significantly DECREASE your mileage as your foot will be consistently closer to the floor.

As to a serious answer to your question, rest assured that for the most part, they come from the factory at peak mileage capability. It will get a little better as it breaks in, but with mileage standards requirements as they are, the manufacturers do their best. I am not aware of any mod that will SIGNIFICANTLY improve mileage. Most truck owners around here seem more motivated to improve "off the line" and "rumble" almost exclusively.

If you find something that is truly of value, you will be a hero on these boards!

Approximately how many miles is considered broken in? I just hit 2,000 miles on my truck and took a long road trip up to NJ this past weekend. 400 miles trip mostly all highway I only was getting 18 mpg. I would have liked to see 19-21 but I'm hoping the reason to this is because the truck isn't completely broken in yet.

You can change all your fluids to synthetics after the initial break-in, and it will help very minimally. I know people are going to say the MPG gains are'nt even going to come close to the cost of going full synthetic, but I think going full syn is something that should be regardless, so just look at the minor MPG increase as a slight return in the investment. Keeping your foot off the go pedal as much as possible is the only way to truly get the best MPG's in these beasts! When the tuners/tunes become fully available you might be able to get a decent MPG increase there, but as with the fluid swap, the initial cost of investment is pretty substantial, and would take awhile to get your money back.

Only way I can break 20mpg on the highway is to drive 60mph or less, with a 70mph speed limit around here that doesnt happen. As mentioned if the manufacture could safely get 2 more mpg with a tune they would do it, gas mileage sells trucks these days.

18-19mpg is about it, exact same with my old 2010 4wd CC hemi, and i'm OK with that, its the 13mpg hwy/city average that hurts. I'm sure a 2wd regular cab would do a little better.

If you want to get 19 - 20 you will need to keep your speed down to around 55mph. As your speed increases so the loss of mpg. My Sport is rated 19mpg, I can achieve 20 - 22mpg if I only drive 55mph. However if I drive 70 mph I end up at approximately 17 -18 mpg depending on if there is hills involved or not. The difference in time driving slower is just a few minutes anyway if you are looking for mpg.

Your highway "sweetspot" will depend on what rear end you have on it. I have a 3.55 on a regular cab and my sweetspot is right around 65-67mph. I just broke 3000 miles and I got 20.7MPG(hand calculated) on a recent highway trip. I had cruise set at 65 the whole way. Route only had a handful of stoplights. My truck is a 2WD Reg Cab and the only "fuel saver" mod I have is a tonneau cover.
