Hey all!

Am considering picking up a 4.6 Bird, as I have same motor in a Crown Vic and it get's great mileage in that sled, plus goes real good with 3.27's out back! What year is the first of the 4.6 (92-3-or 4?) and what sort of gas mileage are you getting out of it???

Thanks in advance!

The first year for the 4.6 in birds and cougars was 94.

I have a 95 with 3.27s and aftermarket exhaust, and I average 18mpg combined. I've gotten as high as 29mpg and as low as 14. It all depends on how you drive.

95 with 140xxx miles. I was getting about 15-16 but i finally fixed my egr so that should help quite a bit. Last tank was only a 1/4 when it got fixed and i got 16 while my computer was resetting itself. I usually get 14 when its resetting on those first 40 keystarts.

I have a '95 with almost 98,000 on the clock and I am getting about 21-23mpg on average.

I'm sure I could get better mileage if I would quit doing WOT runs to get onto the highway, though.

I forgot to mention that my bird has 182,000 miles on it. I'm sure it would get better mileage if it had some new rings and valve guides. A good running 4.6 would get better mpg.

I have 212,000 miles on my 95 4.6, and am averaging about 20 mpg.

If I slowed down a bit on I-90 and I-87, it might improve 2 or 3 mpg.

I always try to match my speed to the road I am on.

Example: I-90, I go 90 mph, I-87, I do 87 mph.

Route 2 is a real PIA....lol

When I first got the car with 58,000 miles on it I was getting about 26-28 MPG. Of course I had a light foot then. Now a little over 2 years later I'm with 131,000+ miles on it I'm getting about 17-19 MPG with the stock 3.08 gear. My foot has gotten heavier, but if I'm somewhat easy on it I get about 19-20 max. I never do the speed limits except for in town.

With a 4.6 I'd say expect 18mpg city and about 24-5 on the highway as an average. Both can go up or down depending on how you drive and all.

You must be that guy that always slows me up on the 201. I think I would have problems if I followed your rule on that road.

Yeah yeah yeah....but I think the gap has closed a wee bit! :tongue:


Due to an unfortunate lack of music jobs this summer, and an unfortunate second-job mandatory time off (104 hours worth by 9/30!), that gap may widen again...shucks...but I say the race to 300,000 on the original engine is still on! :thumbsup:

OK!!!

Thanks for all your responses!!!!

Looks like 94 is the first year for the 4.6, and mileage depends on weight of the foot!!!!

Youse guys are a hoot! ....and a great resource!

Yep, I saw your mileage and went, "Doh, he's catching me!!!" :D

But don't count yourself out yet. My LSC is stealing a fair amount of miles from the MN-12. :eek:

I usually take the Mark for trips, so now the T'Bird only gets the 110 a day to and from work. :eek:

I average 20mpg on a usual week.

This includes 25 miles of 75-80mph down I-40 so I don't get ran over, and about 2 miles of 50ish down US-70 and two back roads.

196,000+, 3.73 trac-lok, MarkVIII TC.

I used to get around 23mpg on the same trip with my 3.08 open rear end and a stock TC.
