New Spark Plugs + No Speeding + Clean Air Filter = 41 mpg
 

Finally... Just need to maintain your car, right? I think this is the right forum.

Got the elusive 40 mpg last tank. Hopefully I can replicate this in the times of $3+ pump prices, eh?

I cleaned my K&N, changed out the old Denso plugs (50K miles on them), changed the oil and didn't bring RPMs past 4K and kept speeds below 65 mph.

I figure the plugs will pay for themselves in about 7 or 8 fill-ups because of the 5-7% gain in mileage. :rockon:

Nice man...Keep shooting for more though! I've got a catback and intake with stock plugs and I get 44 on the highways usually. Gotta love Hondas...

I love gas mileage posts. I also love saying that I'm k-swapped and still get 35mpg!

Re: New Spark Plugs + No Speeding + Clean Air Filter = 41 mpg
 

what did u replace your plugs with? denzo iridium? also i wish i had a 5-speed so i could rack up the mileage...

Re: New Spark Plugs + No Speeding + Clean Air Filter = 41 mpg
 

I have AEM short ram, Borla Cat back, two 15's in the trunk and I run atleast 80 mph for an hr a day. 30 min to and from work, in an auto ex (D17). I still get about 32 or 33 mpg. So I am happy with that.
I run Mobil 1 5w 30 tri synthetic oil with a K&N oil filter. Change it every 5000. NGK plugs every couple years and a tranny service every 6 months.
