Time for an MPG update

[M22KLARS]

I got 11.2 out of my last tank. Is that good?

:giggle:

 

[alrock]

I think you forgot to raise your anchor before setting off on that trip.

 

[M22KLARS]

Yeah.........

 

[Mr_Rich]

17 the last tankful, and 16 on the tank before that one. I had a mix of distance driving with a couple of climbs on some steep grades.

A local a gas station started caring ethanol free gas and I decided to fill up last week and compare gas mileage. All the gas stations in a 50 mile + radius only offer 10% ethanol blend (they actually did some testing in the Rochester area and found ethanol levels to be over twice that). I paid quite a bit more for the non ethanol ($4.00 a gallon :whaa but I call tell you gas mileage has improved. By how much? Can't say for sure yet but I can tell you I have gone more miles between fill ups then before and I still have a 1/4 tank left.

16.5 on good Weeks and when I travel out of town it dips below 16mpg.

 

[LEEEZARD7]

16mpg in 08 h3 alpha

 

[4speedfunk]

Hmmm... I'm gonna see what a SAS/SOA and 5.13's yeilds. I'm thinking it might actually be better than before.

 

[Can007]

I would say, 18 to 19 hwy, am on the road a lot when I use it. Thank god for the good old Honda Civic HB 38 to 40 hwy

I get about 15-16mpg in my 08 Alpha; last tank was actually 16.01. I drive 60/40 hwy/city; with some moderate grades when going to work; going 65-70 mph. When I was in Colorado, I drove 45-50 mph to work and got close to 18mpg. I dropped to 14mpg when i got near 55K for quite some time and was stumped. Eventually looked at the air filter and realized it needed replacing. Put in a replacement (std) and went back to 15-16mpg. I'm getting curious now what gains will I see if I put in a K&N; and change my exhaust.

 

[alrock]

I'm barely hitting 13 nowadays. Did get 14 on one recent tank but I think I had a good tailwind for 100+ miles. Roof rack knocked off about 2 mpg.

 

[06 H3]

Last tank I got 12.2 mpg...

 

[Portager]

I got 12.19 on my way to Bishop, but I had the cruise set at 79 most of the way, the AC was on the hole way and I was going up hill.

On the way back we drove up to over 10,000 ft, cruised at 79 with AC on (+100F outside) and got 12.9.

315/75R16, Alpha, cat back exhaust, no PCM tune (yet).

315/75/16 - 13 HWY at 72 mph.
10-12 city.

Ive always thought my mileage was low in comparison.... no CEL tho... I do have the PCMforless tune...

 

[Mr_Rich]

As much as I like the LS engines, I'm glad I have the I5 in my truck. I'm putting in a lot of road miles lately. I checked my log book and my off-road mileage typically drops to 13 mpg overall and I get 18-19 regularly on my runs up and down to Santa Barbara and back. Around town I mostly get around 15-16 mpg.

That's what I get too.

 

[H32NV]

what tires are you guys running? no light bar's or roof racks? do you guys have the PCMforless tune?

 

[H3Hrly]

I'm still on the original 33s (68K on them:woot. I have Gobi Ranger rack on it, but I removed the fairing. No lights on top yet. nothing else on the truck. No PCMforless.

 

[Bigunit]

Gobi stealth (no fairing), OEM roof mounted off-road lights, BA bumper w/winch & 33" Duratracs.

Hi new here.

2005 h2
Street 12.9
Highway 14.5 @70mph
As most current

Before I got my Flow master American thunder kit
Street 11.5 mpg
Highway 13 mpg @ 70mph

 

[TAPDH3T]

Well I have 2009 H3T Alpha torqued 24" w/ 33" tires, 20x9 wheels, Airdoc, superchips performance setting, and roof rack...
Before the SC and AD I was getting about 275-285 mpt before the light came on... This is the result now...

 

[Former User]

2008 h3 alpha, 305/70/16 bfg km2 (33.1x12.3?), h3t steelies, gobi stealth, superchips set on tow mode, magnaflow cat back system, 90% or more a tank depending the time i'm driving all city, i hate running the numbers but i'm generally about 14.5. I go around 275 miles a tank and fill up 19-20g. I also drive with a light foot. The gobi took away 1.5-2mpg, and i think the heavier steelies took a little away as well. Each steelie according to the gm part info weighs 29.87 lbs, each standard split spoke weighs 21.1 lbs.

Stock i was getting about 330 a tank if my memory serves me correct.

Update on mine

Cruise control on highway @64mph I got 17.2mpg
I was shocked.
Crossed checked with my navi for distance against fuel burned too.
I guess I'm going to drive like a grandpa on long trips. Keeped The RPM under 2K too.

 

[BW_Hummer H3]

Wow I only get around 250 miles per tank on a stock H3 with a V8....
