unfortunately, my old fuel mileage spread sheet got corrupted, but I think I have lost a bit of fuel mileage over the last couple years. It seems I used to break into the 20 mpg range regularly, not im about 19-1/2 most of the time.
Im sure my alignment issues aren't helping. Tires are a bit larger and heavier than stock. I carry around some crap that could go in the barn, maybe Ill clean it out this weekend.

just get you a MAF adapter, it's about 10 bux.
Buy a 3" inlet Cone filter,20-50bux
Remove the airbox.
attach the MAF adapter.
attach cone filter to adapter.
same as this. EBay Link

If you want the aluminum tubed one, heres a $70 one.

id honestly rather get one from nismo or k&n where they have put the time in engineering and testing them. usually the homemade ones pop a CEL. and the aluminum ones arent as good because the aluminium piping gets hot and heats the air going into the engine more than the plastic tubing does. but thats just my .02

This last tank I got around 18mpg. Kinda sad, but that's the best I've ever gotten.

If you drive like a grandma you get better gas mileage, too bad it takes the fun out of everything.

have you had your truck scanned for the knock sensor issue lately?
In town, I accellerate a bit slower than everyone else, on hte highway, I drive flow of traffic or a bit faster. These trucks are really forgiving on how you drive them. they will get similar gas mileage either way, short of racing from one light to another in rush hour traffic.

Fronty noob keeping this alive, I've searched for gas mileage threads and could not find any.... So it seem's the 3.3l v6 with the knock sensor thing fixed avg's about 18mpg... that's not bad, I'd LOVE 20mpg, but I would take 18...

I assume the few people who said they get 14mpg may have not fixed the KS?
I'm really looking forward and getting into the 01-04 fronty's, but if it's 14mpg I'm looking forward too, maybe I'll have to change my mind... HOPE NOT =)

I have a 2010 PRO-4X, have had only an OEM replacement K&N filter, and changed the tire air to nitrogen with a 2 psi gain of 37. After 3 tanks I get a solid 18 mpg around town and 21.5 and have hit 22 mpg on hwy.
Around town I try not to allow my RPM's to get above 2.5k from a stop / start. I have had to punch it now and then around town and I see it go down to about 16.4 mpg. However within a few miles it's back to 18.0. I run the sweet stuff, 91+ octane per my owners manual. Was running 89 proof, but I did not get the mpg I am now. So for now I'm leaving things as they are.

Mine runs right at about 24mpg average. Best was about 26, worst was 20 over the last 6 months (blackberry app. tracking every fill). That is after most all of my mods including conve filter intake, and 2" suspension drop front and rear. Hope to push it up to 25 average after a bed cap!

Bumblebee, that's awesome how much you track your fuel. Really helps me make the decision on getting a frontier, and is a great long term guide.

I normally figure out what mpg I get every fill up but keeping long term track is pretty awesome. I'd be happy with anything over 18mpg, so your doing great!

I get 18 consistently with my 00 fronty. Thats average driving, which nowadays for me is aggressive, with a decent mixture of city/highway. My few power mods, which didnt cost that much, only a total of $250 for intake and exhaust, are helping. Best $250 I have ever spent! I managed to get 20 once last year. If you have a non-sc 3.3 fronty, i would suggest to get the Kool-vue CAI. $50. It requires you to put it together, but 2 hours in your home garage with some simple hand tools will give you a little bit more power and mpgs.

First a bit off the subject:

I have a highly modified 06 Pontiac Solstice, 2.4 naturally aspirated, 143 rwhp and 135rwtq at the wheels. 26-28 on the highway and 23-24 around town. After spending 1/2 the price of the car on modifications (MP62 supercharger, intercoler, 3 belt pulley assy, Exedy stage 2 clutch, header, high flow cat, custom exhaust, custom body panels, custom leather interior) I now have 270 rwhp, 280 rwtq and get 29-31 highway, 23-25 around town. No I will never get my money back, but you can't wipe the smile of a my face. Car is 3 seconds quicker 0 to 60 and all most 4 seconds in the quarter. Worth every penny.

Now back on topic:
01 crew SC (same one MP62) only mod is a K&N CAI. I have had the truck 8 years. In that time it has always drank 93 octane. I see 15.5 to 16.5 in combination or highway did not matter. Over the last month or so I have been experimenting. Removed roof rack .1 to .2 gain to the gallon over several tanks. Then I did the unthinkable, I put 89 octane in it. So far the first tank was 17.2. Second tank was 18.7 but that included a 60 mile trip without a lot of stop and go (saw 20 for about a mile). I am on my 3rd tank of 89, all mixed driving and I am sitting at 17.4 (added a soft cover on the bed) So by dropping to a lower octane that is up to 10 cents a gallon less I have improved my gas milage by 9-10%. Will have to continue and see if I get any knock or if this heat causes and issue, but so far it hasn't
