I think it may have to do with the summer additives or formula, but I'm getting just over 27 MPG with mixed 40% city and 60% freeway driving. I've gotten this three times consistently since late June. My usually has been 24 MPG just for reference.

 

wow that is pretty good mileage...mine just began improving a decent amount when i started using premium. have your driving habits changed at all or are you driving as you normally do?

 

 

i jus put 400 miles on in one tank and filled up15.72 gallons. oh ya i use 89 octane. so i got about 25.4 mpg, and i felt like that i have been driving fairly conservatively.

 

hmmm...not anymore. Don't get on the highway much, but I also don't fill-up until Egg Harbor NJ from Phila. So that means alot of city driving in-between. Best I can do is about 24, lifetime avg. 24.6.

Took that K&N garbage out and put the factory Nissan back in too to see if it helps. That K&N is seriously clogged after about 55k of use, clean/re-oil every 5 k or so. So dirty you can't see the light through it. They said 1,000,000 but they must have been thinking of a march not miles......

 

i get about 450 miles on a tank using 87 regular

anu

 

I can get almost 30 on the highway. Stomping on it all the time I get between 24-26.

 

20 city
34 highway

 

Lately, I've been getting great milage myself. I was usually getting about 17mpg because I was doing very short trips and also several warm-up's a day.

Now with longer trips, and less warming-up sessions, I'm getting a good 23mpg in 100% city driving

 

i get between 19-22mpg around the town, bot on the highway i get 30mpg

 

no matter how i drive, i cant get above 20...its hard to hit 19.5+..and i do mix driving 50/50 street/fwy...so i basically just gave up...i try to stay under 3k rpms for the most part...i love my car but damn woman, high maintanence...takn all my cash flow
atw

 

Damn...$1.499 for 93 ?!
I think my milage has gone up since I put in the Y-pipe
