Rock

So, first the old post below in brown followed by the new post in green

(contamination of the results talk after green):

New 8/12/2012 off the lot with 40 total miles (driven over from dealers other lot).

8/15/2012 341 total miles so 300 miles fillup at 12.4 gallons = 24.2 mpg

8/20/2012 648 total miles so 307 miles fillup at 14.4 gallons = 21.3 mpg

8/23/3012 920 total miles so 272 miles fillup at 12,4 galons = 21.9 mpg

8/27/2012 1273 total miles so 353 miles fillup at 16.0 gallons = 22.0 mpg

9/1/2012 1472 total miles so 199 miles fillup at 9.0 gallons = 22.1 mpg

Average = 300 + 307 + 272 + 353 + 199 = 22.4 mpg over first 1472 with OEM air/oil filter/oil

12.4 + 14.4 + 12.4 + 16 + 9

Will post again after next 1500, see if any diff in investment:

K&N air filter $40

K&N oil filter $6

Valvoline Synpower $30 for 5 quarts

9/9/12 1868 total miles so 396 miles fillup at 16.9 gallons = 23.4 mpg

9/14/12 2135 total miles so 267 miles fillup at 11.8 gallons = 22.6 mpg

9/22/12 2506 total miles so 371 miles fillup at 15.7 gallons = 23.7 mpg

9/27/12 2700 total miles so 194 miles fillup at 7.9 gallons = 24.6 mpg

10/9/12 3036 total miles so 336 miles fillup at 13.8 gallons = 24.3 mpg

Average = 396 + 267 + 371 + 194 + 336 = 23.7 mpg over next 1564 with K&N oil/air filters & Valvoline Synpower 5w20.

16.9 + 11.8 + 15.7 + 7.9 + 13.8

Looks great, that I got an increase in gas mileage;

a couple probs with the comparison, though.

My schedule changed to odd hours having less traffic.

Always have bout 10 miles of 35 mph zone lights going/coming out,

but that can be jammed or completely free, depending on time of day.

For the 2nd 1500 miles, I got to pretty much avoid clogs,

so cannot generalize until I get back same prior schedule.

Only can say city driving tanks mpg; Journey Hwy mpg is good.

don't know of exhaust mods, but I looked in mopar's site and they listed a CAI for the journey at about $400

(but was made of metal, so it looks, so don't know how much colder than OEM setup- which looks good).

Also (best after warranty period) hypertech lists a tuner for Dodge Journey also, to increase Hp, mileage.

Searched and decided on the 2.4l for economy reasons (purchase & mpg few gallons diff)

Here are the records for first 1500 miles, prior to K&N air/oil filters & Valvoline 5W20 synpower.

Will doc later after 1500 miles of the above, to let you know if any diff in mpg.

Should be about 3 weeks

And if anyone should know, would be good to know the OEM oil;

was pretty dirty when I changed it; glad did at this time.
