I know I am beating a dead horse here, but I am looking at my fuel mileage and wishing I could get a couple more. Pretty sure I am around 14 mpg right now. I see posts about Uprev, exhaust with headers and cold air intake might help. If you had to chose 1...which one would it be and why? I am only looking to gain MPGs.

Thanks in advance fella's!

Yes, you are beating a dead horse. The best way to improve your fuel mileage is to get your foot out of the pedal.

 

[Smokeeater163]

Thanks Captain Obvious.....I don't have a heavy foot, I am new to the Titan and looking to upgrade the truck a bit. But since you are a Superior Moderator, I guess you are the all knowing. Unfortunately, you didn't answer the question. So anyone else?????????

The search function works great here, and your original post said nothing about wanting to upgrade your truck. I'm also going to caution you about tossing out insults, you'll find it has a negative affect on your posting capabilities.

Yup. 14-15 is about right. Nothing I did changed the MPG. Nothing. I tried a CAI, Bully Dog, Hypertech, all kinds of stuff. Nothing helps MPG. It's the biggest reason I didn't return this year when I was looking for a new truck. I really wanted the Cummings to get above 20 MPG, but it gets 17 if you're lucky.

And, he wasn't trying to be snotty. Those of us that have been here a while have dealt with these threads for years. There's thousands of threads involving MPG. Nothing helps it. Sorry.

 

[Smokeeater163]

Thank you for the sincere replies fellas. I was unaware of a search option on the forums. I am sorry for the initial reply, but was kind of taken back when that was the first reply.

Thanks again,

So let's say you get headers, UpRev, exhaust, CAI. You're out the door for roughly $2300 not including install. You might get 1-2 MPG's more.

Let's say 2. Let's say you use 25 gallons and get 14 MPG to start. Going from 14 to 16 MPG you'd go from 350 miles a tank to 400 miles a tank. Let's say gas costs $2 a gallon and you drive 15k miles a year. At 14 MPG's you fill up 43 times a year and at 16 MPG's you fill up 38 times a year. You'll save $250 a year in gas. So in 9 years you may recoup your costs best case scenario.

If you're averaging 14 don't do anything to it, you're already in the upper average for gas mileage. I'm happy if I average 13 with headers, UpRev, exhaust, CAI.

Thanks for the break down...didn't really think of in long term. Would there be any other benefits of doing any of those mods?

 

[REDRUM]

smh.. Im at 11-12 mpg with exaust and drop in k/n... and ofc big lift n tires.. haha
uprev , headers on the list tho!

 

[JohnnyMac]

Yeah, I am super happy with my 11... I was averaging 10.2 forever but recently started running Mobil1 0-30 and it's up to 11 now. Woo Hoo! I'd be pissing myself if I got 14....

 

[seymore4]

I say Uprev tune, hands down. By me of course. (I am a bit biased tho)

Oh don't do it for gas mileage. Do it for speed. You can add more horses doing all of that. Just don't tell the wife that you're going to save MPG, cuz you won't.

[Smokeeater163]

Well I just filled up and double checked my mpgs....and it came up to 11.6 mpg. I disappointed myself with my first calculations....forgot that the wife put a little gas in it when I wasn't there. Bummer....well I guess Ill be saving for some upgrades for S's & G's. Still looks good with my boat behind it.....:devil:

There's not a whole lot you can do about mileage on these trucks. I have found the basics still work for me, though.

Keep your tires aired up properly. A 3-4lb drop in tire pressure on my truck carries a penalty of .5-.75mpg.

Keep your speed down on long highway runs. My T gets almost 1mpg better at 65 versus 75.

Use good oils and good gas. Pure synthetics, for sure.

Don't carry extra stuff when you don't need it. A hundred pounds of extra gear will rob your mpg.

Get the lightest appropriate tires. I'm paying a bit of a price for my tire choice, but I wanted E load rated, with extra sidewall plies for durability off road. At roughly 65lbs, they're 15lbs heavier per corner than the oem in the same size. All that costs mpgs.

Don't forget to clean your Mass Air Flow sensor with appropriate cleaner at each air filter change. I run 5 extra pounds in my tires at the expense of wear. Also, O2 sensors age, (are a normal wear item), which slows them down in response, which in turn makes the computer call for rich AF ratio results. Heated sensors (4 and 5 wire) have a normal life of 80K with good gas.

From experience.....towing costs extra....a lot extra.

 

[SHROP]

What i'd give for 14mpg. I'm averaging 9.5-11 depending on how much highway driving i do.

 

[Smokeeater163]

Luckily, I only have about a 1/4 mile tow to the lake from the garage. I am running 45 lbs in my tires...(what the tire recommends) I just purchased the truck less than a month ago. It has 118,000 on it and I have no idea when or if the O2 sensors where ever changed. Is there a way to check, or would it be easier to just replace them? Also, what cleaner do you recommend for the Mass Air Flow Sensor?

Thanks,
Smokeeater

 

[mulletcutter]

I get maybe 250ish per tank. 34s and a V8 so dont expect to get great gas millage

I do a fair amount of business with NAPA and that's where I get CRC branded Mass Air Sensor cleaner. I'm sure that Autozone and others will have the same or similar products. MAF systems are fairly delicate and you don't want to use brake, carb or any other cleaner not specific to the job.

The 'important' O2's are the ones before the cats since they have the A/F reporting job. The ones after cats basically only tell the computer that the cats are doing their job. An O2 would be fairly easy to spin in the bung if they had been replaced within the past 20K or so, given the miles on the odometer you have. If hard to remove and they appear ancient and crusty on the exterior, then they are. If you pull one and there's anti-seize on the threads, then it's a replacement, but without some other info, you won't know when. If you remove one from before a cat and it's sooty, then it's another sign of running rich. Vacuum leaks can also cause the rich running, which in turn screws up the O2s. If the sensor of the O2 has what looks like a silver gray fingerprint on the sensor projection...it's shot. That means someone touched it during installation...a no no.

A black or brown crust would indicate oil contamination....which will destroy the O2 performance in a heartbeat. Usually, but not always, the cause for that is a bad PCV valve. I pull those and replace at 40K since they're so cheap.

Truck bed cover and cold air intake gettin around 17 mpg now
