Hey Guys what can I reasonably expect to get as fuel economy.

I have a 2001 4.7 4wd QC and I am getting 12.2 average mpg. Is that low or normal?

It seems low I used to have a 74 Bronco 302 headers and 3/4 cam and 650 holly on 37 inch rubber and I was getting about 10-11 mpg.

Thanks

 

thats normal for my 5.2 but yours should be at least 16

 

yeah im pretty sure you should be gettin 16-17 mpg with the 4.7.

 

im at 15 ish over the winter. now that its getting warmer and the winter blend gas is going away im getting 17 ish as of the last few weeks. i have the 4.7 awd quad cab.

 

No way a 4.7 QC is going to get 16 at least in the city. I average 12-13 in the city, and upwards of 19-21 on the highway. Turn off O/D in the city that may help a bit

 

Plus it depends how much stopping and starting you do in the city. If you live in a congested city with a lot of stop lights you are going to get worse mileage

 

all of my 150 miles a day is hwy miles, except for 20 miles to get me to the freeway(10 miles each way to the freeway) i have gottin 18+ in the past as well.

 

You should see around 14-15 no problem. I see around 11-12 with my 5.2. In the city with lights and what not I burn through a 1/4 tank in about 10-20 miles.

 

So a tank should get me about 400 kms 200 miles? Things like a o2 sensor will have an effect I think the cats are original 214000 kms they maybe getting clogged or no?

 

With my bad mpg I see about 250 miles out of a tank, on a 4.7 you should see 300 miles at least.
