Hi, Need some info. just made a 619 mile trip with my xcal 89 tow program in and got 14.80 miles to the gal. Is this normal. What can i do to get the gas economy back up in the high teen at least. Any help would be helpful.

You are going to hear this one alot. Slow down. I read somewhere that driving at 60 mph uses 10% less fuel than driving at 75 mph.

My current average is 16.

I noticed a nice little jump in mpg when I replaced my upstream O2 sensors. How many miles are on your o2 sensors?

Ever use SEAFOAM on your engine?

How about plugs? how many miles on your current plugs?

Air filter? how long since it was changed or cleaned?

Tire pressure?

Nag nag nag.

 

01 s'crew with 1715 tunner on 91 perf, 17.6 mpg

 

06 Lincoln Mark LT 87 perf - 16.0.

70/30 interstate/surface streets - drive about 70 mph on interstate. Reserved driving habits - not getting into the throttle.

 

Just drove from Md to Nc 460 mile trip and got 19.3 at around 70

 

87 perf or 92 perf driving like a granny all city driving I get 11mpg. Period. 5.4 with 3.73 4x4
It sucks.

 

87 perf, Airraid, Magnaflow 05 4x4 S.Crew.......12.1 if I drive it normal.

 

15-mpg combined freeway/street, not gettin' on the throttle a lot but definately not gandpa'ing around.

Gotta nice 2600-mile trip coming up in about a week, so I'm really interested how it's gonna do with mostly freeway/cruise control.

'05 Lariat 5.4 4x4, 3.73, Edge EVO level-3 (92 octane), Magnaflow, K&N, Mobile 1

 

Just under 12, in the summer it will go up to about 14. 4x4 5.4 145wb. Banks exhaust. Have a tuner, fans and af1 coming.

I find it hard to drive below 80 at times.

 

14 all the time. Half freeway, half city. 03 4x4 5.4, bone stock..........but not for much longer!! AF1 in route and on waiting list for X cal 2.

 

14 here no more but sometimes less , mixture of highway and around town.

 

I average 14.8 driving 80-85 for 20 miles each day with 5 miles of stop and go city traffic at each end. I dont beat on my truck but I do drive it Hard!

 

That Ain't Bad Numbers ATS!
