What MPG do you get with your 4.0? And what improved it?
Mine went as low as 10 last winter but around 16 in general. Nothing (tuner, CAI, exhaust, headers, throttle body spacer) improved it yet as far as i can see.
do you stay on one tune or switch it up a lot? also do you manually calculate your mileage or go by the cars computer mileage? lol I stay on my 93 octane hybrid tune for the most part. I would think changing tunes & octanes a lot might screw with the system
no, i kept my 91 octane tune since april but my battery goes dead often and that might be similar. i would go 93 too but in Europe (where i'm from) gas is at least twice the price in the US so i don't bother. i use the car's mpg calculator but i think it should be quite accurate. by the way, is your city hilly?
I just purchased a 2009 V6. i also get about 11-13 in city. no hills. lots of stoplights. clean filter. 87 street tune by bama. and no other added mods as far as i know if.. frustrating because i should be getting much better. anybody have any advice?
It you literally just put the fuel treatment in you have to give it a little while to work through the tank and system but hell I've never had that bad of mileage driving the dog **** out of mine
I have a 2007 with close to 50,000 miles I have a ford racing cold air intake, headers, dual exhaust with x pipe, and for the most part I run the 87 octane street tune from Bama. My fuel mileage doesn't change when I change tunes it seems to stay about the same. If I am real froggy with it I get 16mpg . for the most part I average 19 mpg. On a road trip I get 21 almost 22 mpg and that's doing mostly 80 to 90 mph.
This may be a dumb question but have you changed tire sizes on your car and if so did you reprogram the speedometer for the different tire size? If you have a smart phone you can check your speed with your gps.
i've seen that at the automatic, it really helps to take your foot off the acceleration pedal and let it go by inertia instead of keeping the speed with the accel pedal. also at about 40mph mine gets the best mpg. i'm waiting for those retrofit hybrid kits to add, it really should be interesting other solution i can't find
X1R is still in business?? I used this stuff in highschool and haven't seen it since. I used the friction reducer in the PS pump on all my Fords. Made them pretty quiet.
Power steering pump. Lol. Our older fords have a kind of noisy pump so it helps. But I haven't seen X1R anywhere around In a long time so I hope it still works for you.
aaa, nice well i don't see much of the difference but i used it in the engine oil, power steering, transmission...:lol: the fuel additive did do some improvements on my pollution so i could pass the car's inspection

Put sea foam in a vacuum line. But do very little. Pour slow. And if you do it right you will hear the engine struggle for a second the rev a lot higher. Keep pouring a little bit more in and the rev the car. If you see blsck smoke comming out of exaust pipe you did it right. It gets rids of all the carbon build up
yup, it's overdrive and it gets into a higher gear to improve mpg and reduce engine temp. but you need to turn it off when you have a trailer or go up a hill. with OD it shifts at around 1500-1700 rpm and without at 2500-3000
well... if you turn it off, then you have higher rpm so more hp which if you keep stopping and going could help by not running rich, i think. but from a certain speed higher, definitely hurts the mpg
You guys are so lucky. All of you. Lol. I get 9 mpg no matter what I do. City. Highway I get 32! But 99% of the time I drive in traffic so horrible mileage. Tried everything n given up already. Bone stock auto, 39000+ miles on the clock.
