The argument that a CAI and other upgrades will pay for themselves is not an instantaneous one. They will pay off in the LONG RUN. If you don't keep your vehicles for but 6 months to a year then ya there is no point to an upgrade but that isn't just for mpg upgrades. If you plan to keep a vehicle for a few years or till it dies on you then it is worth it. No one claimed you will see your money back from the upgrades with a snap of your finger.

 

No doubt. Not saying anyone shouldn't. just a perspective on the ROI of upgrading.

Or sometimes it's just screw it I want to MOD something and thats cool too.

The bug was a POS, I keep cars 10 years

 

I have a 2012 screw with Ecoboost and I get about 14.5mpg on average over the course of a tank. Should I have it looked at? I would think it should be much better than this as I don't drive hard and have a flat 18 miles to/from work each day.

 

I have a 95 F-150 L6 4x2 Automatic.

My last MPG check was 13.25mpg ....HORRIBLE...and that is with an empty bed - not even a tool box. I drive mostly highway, in slightly hilly terrain in western NC.

I have done a full tune-up: New plugs, rotor/dist, air filter, oil change, fixed some vacuum leaks, Sea-Foamed the intake, rank Fuel Injector cleaner thru it, and cleaned the throttle body with intake cleaner.

The only thing that can be hurting my mileage is the tires...they're 275/75R -15

I'm getting new tires on it today 235/75's hopefully that will give me a couple MPGs back.

But still, I can't see the tires dragging down my MPG that bad for a L6.

I'm thinking with the new tires I should be getting around 16mpg.

Anyone know what I should expect to be getting, or if the larger tires can account for that much reduction in MPG?

Can you guys offer any other suggestions to help improve my MPGs?

With this kind of mileage makes me think "Wow, I could of had a V-8"

 

An air filter doesn't increase the volume of air. A naturally aspirated motor can only draw so much air in per stroke. The stock system and any paper filter isn't starving the motor of air. This is why there is no difference. The "power" is very minimal and is usually just a felt throttle response difference.

 

I'm seeing the exact same on my truck, it's driving me nuts. The dealer said "mileage will vary" and as long as its close to the range on the sticker then it is what it is. I went to complain but the service manager got fired and I'm moving right now to the east coast so ill deal with it then. Let me know if you find a solution!

 

Only getting about 13.9 to 14.1 in town on 4 Wheel drive constantly because of the snow with only 1000 miles on it. I used a half tank of E85 to try it out and I was getting 14.4 before that. I dropped to 14 on the highway on 2 wheel drive using E85

 

Hi Guys,

I just got a 2013 F150 XL RCLB, 3.55 Axle Ratio. I was looking for a truck that would enable me to haul and tow while still getting acceptable MPG. I've enjoyed the thread and thought I'd post what I'm getting at 1000 miles. I added a TonnoPro Tri-fold cover and a K&N air filter as soon as I got the truck (100 miles). Most of my miles are freeway. My family lives outside St Louis and I'm stationed at Ft Knox, so I commute about 280 miles each way most weekends. During the week I drive very little, but its never above 35 mph with lots of stop signs. I took the advice I found on this thread and keep my max mph to about 65 and I accelerate and brake smoothly. The in dash computer shows that I'm getting 21.4 mpg lifetime. I did the math at my last fill up and it came out to 22.66 for that tank of gas.

I'm really pleased. It seems that, in real driving situations, it's tough to get the advertised mpg. In this case, I'm just about dead on. Because of my weekly commute, my wife wasn't crazy about my decision to buy the truck. She drives a Honda CRV and gets about 26mpg. We're both pretty impressed that the F150 is getting such good mpg, while offering so much more utility.

 

When do the MPGs start to improve? 5-10-20k?

 

What kind of settings do you have on your evo chip? i just bought one for my truck and im looking to improve my mpg's.
