MPG observations

[hectik1]

Just got back from my first road trip with my MS3. Started at 6600 miles on the clock. 600 miles from my door in IL to Harrisburg, PA. 32 MPG home to Ohio. 29 MPG from Ohio to Pennsylvania (this included some mountain/hill driving). On the way back, 29 MPG Pennsylvania to Ohio. 30 MPG Ohio to Indiana. The way back couldn't use the cruise as much due to the additional traffic. MPG definitely go up on the highway using the cruise control at every chance. That seems to be the major factor.

Just thought I would share.

bleh, im averaging 25.5 to and from school. in all actuality it's around 23 up and 27 back due to the uphill downhill factor. not only that, there are a lot of lights and traffic, no hwy here. but im glad to see that ppl are getting to the 30's at some point

Pretty consistent 22 mpg city or short highway trips (under 20 miles), 24-26 long highway (about 25+ miles at a time)

i would have to say that is pretty much where i'm @ right now. my car is still relatively new ....less than 2k miles so I guess i'm enjoying the novelty of having a quick car, so driving spiritedly often gives me that type of mileage...prolly a lil worse. the best i've gotten so far was 25 mpg for a tank with a mix of highway & city prolly about 60/40 -- that was babying it like crazy and using cruise all the time (just wanted to test out what i could get)

Mixed driving (sometimes hitting full boost) I average about 25 MPG.

Speed, or lack there of, has a lot to do with good highway mileage. If you keep it to 60-65mph, I bet you can get 32+ mpg, but since the norm seems to be in the 75+ range these days just to keep up with traffic, everyone is burning a good 10-15% more gas then they would if they drove the speed limit. We did a road trip with our MDX yesterday, kept the cruise control on 60-65mph the entire way and averaged near 27mpg with an SUV. Not shabby. Of course everyone was flying around us doing 80, but that's ok. They can get to the gas station before I do. Since it's costing me $70+ to fill the freaking tank on that thing, I'll leave the house 10 minutes earlier to get where I'm going without having to drive like I'm on the Autobahn.

I'll get a good gauge on the MPG my MS3 can get. Going from Concord, CA (SF bay area) to Grand Junction, CO., it's right at 1,000 miles each way. HWY 80 is a pretty fast road and pretty straight when you get past Reno, NV all the way to Salt Lake City, UT. A long stretch of HWY 80 is posted 75 mph through NV, still only do 79 mph. I figure anything about 80 mph and you're looking for a ticket. I've been told since they give you 75 mph already, they don't let you do a lot above that. I usually do about 72 mph in the 65 mph zones around here, never had a problem. It's about 16 hours to make the run, probably won't do it all in one day, getting to old for that. Will report on my MPG, not going until 8/2.

I got the 32 MPG averaging between 70-75 MPH.

Round trip to Baton Rouge last weekend. Trip over was still breaking her in, so much varying of speed. As slow as 55 with many top-gear accelerations to 75, 85, 90 or so. Max speed 98.6 according to the GPS. 30.4 mpg, hand calculated. Return trip was more my style, since she now had over 2 kilomiles. That mileage was 28.8. Absolutely satisfied with her road manners. Really cool to be running around 80 in 6th and get 100 with just a nudge of the loud pedal.

$70 a tank?? that's nothing.. i'd be happy to fill up my 08 Superduty for that.. it costs a good $135 per tank in my truck... that's why i bought the speed for my daily driver!! Diesel fuel is almost $5/gal now.. But i do love my Speed!

I hope you use that truck for work!

Visited California last month -- saw diesel @ $5.61 If I were to fill my Ram from "fumes" here, it would be about $105 or so. Filled ('bout 12 gal) the Speed last weekend -- $52

 

[Smokin08]

my '08 F250 is my "pleasure" vehicle now on my insurance.. I love it and would drive it everyday if diesel was still 3.00-3.50/gal.. but she is only used to pull my 74 bronco to and from the trails now.. and the occassional trip to Lowes or Home Depot or a nursery for landscape supplies... it sucks but i'll never get rid of it!! My silver speed is a great daily driver.. and i've already put 3,000 miles on her in a little over 6 weeks.

I average 26 mpg.


Definite decrease in MPG between 60-65 and 75-80. By definite I mean the difference between averaging 26 and averaging 22 on a tank.

29.7 with mods

I got the 32 MPG averaging between 70-75 MPH.

How are you computing that?

Do you look at your Car's computer or are you doing the Odometer and Receipt method and using your handy cellphone's calculator?

Unless you had a really good tail wind, I find 32 MPG at 70 MPH hard to believe. Seriously.

Was your A/C on?

I get the Cruise Control Method. But that's down right crazy MPG for this type of car at that speed, not that it's fast, but still. Pretty good. You're obviously a very disciplined driver. I couldn't hit 22 MPG highway to save my life.

 

[jwdp54]

i try not to look at that information since i bought the car to go fast lol
but it is good to know our cars can get good mpg on trips. thats honestly the only time i would worry about it.

Doing it the old school way with the calculator.

Well IL and IN are pretty flat. I didn't have the A/C on, and used the cruise control almost the whole time. Yes it takes discipline. I average about 25 MPG driving to and from work too.

Why would anyone drive TO Harrisburg?
I'm constantly looking for reasons to drive away from that town!

So far on my journey from Harrisburg to Miami, to Key West and then to Sarasota, the trip computer says 28.4.
I've been trying to keep the revs under 3K. I notice that the mileage suffers once the boost increases the demand for fuel.

I haven't done a long trip on the highway to empty a complete tank yet since I've had this car, but I drive 75% highway, 25% stop and go to work. That's about 60 miles on the highway and 20 stop and go per day and I've been averaging about 25-26 mpg. When I'm on the highway, I set the cruise control at 70 unless I need to pass. I notice that the current mpg reading reads between 33-35mpg on a level surface. However, I think that gauge is bout 2mpg optimistic from my calculations after fillups. The average mpg reading is always at about 27-28mpg when I fillup, but I've never gotten more than 26. On a level surface, no wind/tailwind or with drafting, it may be possible to get 32mpg on the highway doing 70, but I couldn't see myself getting more than 29-30.

I'm not quite sure what you're doing to only get 22mpg on the highway. You've obviously got a heavy foot.
