Check this out... my highest single-tank average thus far on my GT. I'm pretty pleased with that!  Title fixilated for fat fingers.  -FB (Message edited by Swordsman on June 17, 2008) (Message edited by ft_bstrd on June 17, 2008) | ||

Heheh, thanks!  ~SM | ||

Even my 93 lx 5.0 wasn't bad when you short shifted and didn't drive it like a mustang. | ||

The new Corvettes can pull low 30s if you drive them easy on the freeway. | ||
| Swordsman |
Yeah, the MPG for those Corvettes is pretty impressive. Granted, they're shaped like a wedge, and my Mustang is shaped like a brick! Pretty impressive what they can do with 8 cylinders these days. ~SM | ||

Swordsman...  I want a Mustang! | ||
| Simple |
i had a 6spd '97Z28 and i made 30-40 trips from IL to CO (~1140 miles each way). she would routinely pull down 31mpg's. 6th gear cruising ~78mph at about 1800rpm. then i modded the hell out of it and knocked it down to about ~20mpgs  what year is your mustang? how does the computer mileage match actual receipt calculations? | ||

My 08 Charger RT gets 25MPG's so I am happy with that seeing as it has the aerodynamics of yes a BRICK! and weighs over 4,000lbs. but that hemi is a GREAT engine.. Mustang was my 1st choice, but could not "easily" fit two children in the back seats... | ||

They're trickling down the cylinder deactivation from trucks and SUVs into passenger cars more and more - I don't *think* the Mustangs do it, but doesn't the Hemi in the Charger? My little 3 got over 32MPG on the way to PA and back the other day. Considering it's only listed at 29 highway I was really damned happy...guess it's finally getting nice and broken in at ~6500 miles. I'm about to break the Ram out again to make some Home Depot runs and go camping in August. It needs a new battery and was put away with MAYBE a gallon left in the tank...I'm not looking forward to that fill-up. | ||

Darth, Ford does not have any engines with cylinder deactivation. GM has had it for years, starting with the V8-6-4. It didn't work well back then, but modern technology allowed them to bring it back. GM showed it in the Cadillac Sixteen and Cien concept cars, and then it started appearing in 2005 with the 5.3L Trailblazer and 3.9L Impala. It has trickled down into most of GM's pushrod V6 and V8 engines. With the Dodges, it came with the 2005 5.7L fake "Hemi" engines in several Dodge/Chrysler cars and trucks. The 5.7 is the only one with it. Honda has it on a few 3.5L V6 cars, but there system has a rougher transition, and requires active noise and vibration canceling to make it less perceivable that it's not in V6 mode. | ||

Sword - what kind of driving was that? City? Highway? Combination? I can't figure out how the EPA gets their MPG figures. Maybe all my cars are freaks, but I also do better than the rating. The car I own now claims 21 city, 29 highway. I usually get 26-28 around town and 31-32 highway (and have gotten as high as 37.7 over a 600 mile trip). | ||
| Froggy |
XL1200r, I noticed the same thing, my 3.4L Monte Carlo is rated for 19/29 under 2008 standards, yet my lowest take ever was 28mpg. I average about 33mpg and a all highway tank will get 37+. | ||
| Swordsman |
Simple, a friend of mine had a slightly older Z28 that did nearly the same... the RPM at 70 mph was crazy low. I use the computer calculations. If it knows exactly how far I've traveled (odo), and exactly how much fuel has been used (which it does, or the EFI wouldn't be worth a flip), I figure the calculations are more accurate than mine. To answer the question, 85% of my driving is open highway. I always do my calculations per entire tank. ~SM (Message edited by Swordsman on June 17, 2008) | ||

That's what I thought, Froggy. Ford's big thing is turbos at the moment - 'next step up' power without the attendant gas consumption. V8 power from a V6, that kind of thing. To my knowledge, that particular engine won't hit dealer floors until the 2010MY. Starts in the MKS and trickles throughout the rest of that platform (Taurus/Sable, Flex, and my program). They call them EcoBoost or some goofy @#$%. I'm pretty sure they're working on a I4 version as well, but may they're just stealing the Mazda 2.3 turbo and using that rather than starting from scratch. ...on second thought, that would make way too much sense for Ford. Oh, and Swords - at least on my 3, the onboard computer underestimates by about 3-4%. I was actually rather surprised, but I consistently get a little over a MPG more than it's reporting.

I rented stang it got me 12 mpg. According to its on board calc. Maybe it was all the stop'n'go and the top down with the AC on full blast.  | ||
| Froggy |
Barker, the door handles are not pegs! You shouldn't be trying to scrape em! | ||

I use the computer calculations. If it knows exactly how far I've traveled (odo), and exactly how much fuel has been used (which it does, or the EFI wouldn't be worth a flip), I figure the calculations are more accurate than mine. On my car, the computer doesn't calculate when you're stopped with the engine running (burning gas but not moving) - it only does a moving average. As a result, my actual mileage is about 1 MPG lower than the computer reports. | ||

Hey simple, I had the same car. 6 speed LS1 with a six speed, t-tops, sport appearance package and Hugger Orange. That was a damn fun car. | ||
| Simple |
well, my '97 was an LT1 hardtop. last year for the LT1. my '99 LS1 was a white auto with t-roof and it only got about 21/22mpg's. 3500rpm stall converter doesnt help mileage. hugger orange is tits! i would love to have an HOSS 6spd/hardtop!! the 6spd cars are where its at, thats how GM got around the gas guzzler tax on them | ||
| Badlionsfan |
I drove from ohio to daytona 2 years in a row, first year in a 98 ve gti 2.0 5 speed, the next in said 99 z28. I made the exact same fuel stops both years, just made about an hour better time in the Z.  | ||
| Simple |
hahaha i'm not tellin! they like being in the triple digits!! | ||

I've found the best MPG mod is always gears. had a `99 S10 with a 355CI and the engine dyno read off an impressive 404HP/310Ft-lbs. 700R4 with a kevlar valvebody shift kit...I could go on about the mods and stats but my big secret was that I had 2.73:1 gears! 80 mph at 2K on the tach. One time I had just under 50MPG. I'd still have that truck had I not been a tard and blown the engine to show off to a bunch of girls....  | ||

Back in the day I had a new '94 Vette. LT1 auto, sequential FI, 300 BHP. It averaged 28.7 MPG on a trip from Tampa to Knoxville and back at around 80 to 85 mph and a quarter of it in hard rain. It was always doing 21 to 23 around town. My wife has an '05 Mustang V6 auto. We did a trip in the mountains Cherohala, Blue Ridge Parkway and around Asheville NC. It did no better than 22 MPG running easy. Must be the mountains make it suck some more fuel, however there are equal down hills for lots of coasting. | ||
| Xl1200r |
Etunnely - You'll still use more gas going up a hill and coasting back down than if you had just driven on flat land. Speaking of high gears, I had '78 Monte Carlo with an '82 Vette engine in it (was a Crossfire motor but converted to 4bbl). I'd say around 330hp or so. Turbo 350 trans and 2.51 gears. Didn't really do much highway, but averaged 12-15mpg around town. I should have never crashed that car... | ||

Funny this gets posted today. Did anyone see the post on Jalopnik today about the 1981 mustang that runs on "white powder?" Check it out for a good laugh http://jalopnik.com/396208/the-1981-mustang-runs-o n-white-powder | ||
| Miamiuly |
I'm pretty sure we have a LOT of cars running on the white stuff around here in Miami. I think they convert the white stuff to something green and trade it for a liquid at the pump- but still runnng on white. Then there is the sugar industry, the other white stuff. | ||

Long distance cruising on flat land is a friend of good gas mileage. The inertial losses from accelerating and deccelerating kill your mileage. Driving around my hilly curvy area, I get no better than 14 MPG in my Isuzu Axiom with a 3.5 V6. I'd bet that on an interstate in Florida I could wrangle better than 25 out of it. | ||

I could squeeze 25 mpg out of my old 2003 Cobra, and it made 520 rwhp. I had a viper-spec T56 in it, so it had a .5:1 6th gear (just like the Vettes actually). Mind you, it got 13 in city driving. Now my truck is a different story. 15 mpg tops on the highway, and 10 around town. |
