I've read a million posts on MPG for the 8. I saw one post where the guy posted great MPG, and only 1 quart of oil used in a bunch of miles.

Please post if you get bad (12-14), ok (15-18), or good (19-23), or GREAT (24+) MPG and also how much oil you use. How often do you go through a quart of oil.

I am curious if there is a correlation between seals, MPG, and oil usage.

I get 17-19 (ok-good) around town, with about 23 HWY doing 75. I used a quart of oil by my 1500 mile mark.

17 mpg average over 3,200 miles. One quart of oil in that time.

 

I get 13 miles to the gallon never more. I used 1 qt of oil in 1500 miles. I am a little disappointed in the gas usage as most others seem to get better. I have 3000 miles on the car now.

 

16.5 hyway 1/2 quart oil every 2000 miles.
I drive pretty easy 8000 miles

15 Highway 12 City and I've put in 1 quart in 1500 miles

 

17-19 around town, 23-25 highway, and a quart of oil very 2000-2500 miles. 17,000 miles and counting...

 

Average 18.5 mpg mostly city (89 octane), 1 qt of oil every 2000-2200 miles (currently at 18000 mile mark)

 

I get betwen 18 and 25 mpg depending on type of driving in 5000 total miles & less than a quart of oil.

 

1500 Miles - 1 quart oil; 17.0-17.4 MPG (driving 90-100MPH, rev 6000-7500) and 17.8-18 MPG (driving 60-80+MPH; rev 3000-4500RPM - kinda granny driving).

 

16 to 18 city
21 to 23 hwy
1 Qt every 2000 mi.

 

- Averaging 16 mpg city, 22 Hwy (fairly agressive driving)
- Consumed 2 quarts in between 3 oil changes (every 2500 miles)
- 9800 miles total, and running stronger than ever :D

 

20 mpg suburban driving, 24-26mpg highway. Shell 93. June 2004 build, stock AT.
1 qt. oil for 3k miles. 6k miles on vehicle.

 

Um, you forgot...

MT v AT (VERY IMPORTANT)
UK v US (gallons are different sizes)
Octane rating (makes a LOT of different to mine when I put Optimax or Ultimate in.)

For the record I get over 20+ to UK gal consistently on long journeys, and I use a litre of oil every 3000 miles or so. I use the range of the engine, so I neither granny shift nor screw it, something in between.

On a track day I got 9.5mpg and used a litre of oil in 100 miles.

 

6MT, 1200 miles, 1/2 quart of oil, 15-18 mpg city

 

6MT, 1700 miles, just topped up the oil with 1/3 quart. Every tank has been right around 19.5 w/Mobil/Exxon 91. No extended highway trips yet, but I expect near mid 20's

 

automatic, 12-13 mpg never more, i dont know my oil level, i have 7,000 miles
i dont think i have the M flash. i'm bringing it in on thursday to get it done, lets see if it improves my gas miles

 

Much like you sir, 17-19 mpg. 5,000 miles, two oil changes at dealer, and almost
1 full qt added on my own in the last year.

 

6MT, 4500 miles, 15-16 MPG (driven pretty hard), 1 quart per 2000 miles

 

About 18mpg on my AT, 2 qts. and 2 oil changes, now at 10,000 miles. See my mileage log in my signature for the details.

 

6MT
1600 miles w/ no added oil needed yet

14-14.5 mpg about 80% city/20% freeway. Granny driving mixed with a little aggressive driving. Granny being shifting before 4K rpm, more aggressive shifting at 5-7.5K rpm.

15-15.5 mpg about 80% city/20% freeway. Granny driving.

17-19 mpg 60% freeway/40% city. Granny Driving.

I use Shell 91 vPower.

 

3900 miles, one oil change, one half quart added. 18 mpg in town, 20 - 22mpg mostly w/ up to 24mpg once on the highway. (75-80 mph) Easy driving. 6 speed, U.S. gallons.

 

thanks to all who have replied.

With 24,000 miles on the Odo, she averages 22.3 MPG, and since I change my oil every 2,500 miles, there is no oil added or needed inbetween changes. 85% Highway, using Shell or Texaco 87 octane, M Flash.

 

Keeping a check on your oil level will improve your mileage for sure!

(And, will also stop your engine melting as a bonus.)

 

12-15 mpg in the city 20-23.5mpg on the highway big difference for some reason. i use a quart of oil every 1000 miles. 6mt
