what kind of MPG for the 4.6

[mrltd]

Looking at a 98+ marq's. What kind of milage are you guys getting highway?
I drive about 80% highway on my commute...the commute is almost 200 miles a day.

Well my vic doesn't get the best but it is the P71. My dads old 2000 GM got 29-30 MPG highway, it had single exhaust and 2.73's. My dads new 03 GM LSE gets about 24-27 MPG highway cause it has 3.27's. If MPG is what you are after get a granny geared one. Good luck!

:stupid:

My dad's old 96 Vic with 2.73s got between 26-33mpg

On the road trip last year I was pulling a best of 27 with 3:08s.

My 2000 got 29.3 mpgs with a K&N fipk, the factory dual exhaust, and 2.73 gears. When I use 3.55 gears, I used to get around 22-23 mpgs with the dual exhaust and K&N fipk. On the last trip I made, I had also added 2 Flowmaster 50 series SUV mufflers and mileage increased to 25.4 mpgs.

That's crazy. My protege 5 with the friggin 2.0L 4 banger gets 27mpg on the highway on trips and barely gets 30mpg on my commute....

Guess I'll just go and get a 98+ marq and commute in comfort...

26 @ 93 octane but thats only if the roads aren't clear and straight
Last noted range using trip meter was 390 Miles

your protege! d00d my 6 gets a whopping 18.5!
Hows the house?

Heres the STRAIGHT UP TRUTH. Assmuing a 2.73 RAR you can expect total all highway MPG 24-27. With a 3.27 RAR 21-23mpg. I drive a 3.55 geared P71 vic, This is my 5th CV. You name it, I had it. I currently average 16-18 mpg in a 99 P71 CV at 85mph average speed. My driving style did not change, my 97 with 3.73 got the same mileage if not better.

My '97 CVPI (with a 3.73 ratio) gets right at 20 - 21 MPG at highway cruising speeds.

I have a 1992 Vic LX what can I expect doing once I put it on the road?

[evillally]

My HPP actually did great on gas. My average was 24 MPG overall with 3.27's! That was probably the most fuel-efficient vehicle I ever owned...

With a good tune (and stock rear differential ratio) there isn't any reason why you shouldn't get 25+ at highway cruising speeds.

Of course mileage will vary depending on how 'hard' you drive the vehicle.

My 87 vic with 3.73's got 24 mpg...the wagon running really rich with 3.73's gets 19-20.

390 to a tank isn't too bad. Better than the protege...and that has a 14 gallon tank.

House is good... The 6 gets 18.5? Man mazda sucks. I'm driving 180 miles a day though.... The wagon can make 1 day on a tank of gas. Then there isn't enough to make another complete commute. Ran out of gas last week 30 miles from home, luckily I coasted into a gas station. 25 bucks a day on gas...

My definition of highway cruising speed is 85mph
