WHAT IS EVERYONES ACTUAL MPG, I FIGURED MINE OUT ON THE LAST TANK OF GAS, AND ITS A FLAT 14 MPG, DOESNT THAT SEEM LOW?

14-16 so far for me...

14 for me then added the k/n kit and last tank checked was just under 16

which kn kit did you ad the filtercharger or just the filter

the full kit pd 208 for it

To gr8ntr did you notice any more power or throtle respone and where did you get yours

Thanks

i got mine from the local napa parts store
as far as the power maybe abit more not alot
i got mine tryin to get better mpg
it does make it alot louder

I've gotten between 15 and 17.89 took it off roading in the snow guessing I got about 13 there lol

where did you take it off roading in the snow

How is everyone driving (city, highway, what speeds, etc.)?

I'm thinking about buying an H3 before the end of the year BUT the gas mileage is something I have to think about - especially city driving.

Thanks for any info.

BTW, 14 mpg? Ouch. I do understand and can appreciate mileage improving over time. My current ride, 2004 Mazda RX8, got horrible mileage the first 17k miles. I was getting about 14 mpg with mixed driving. Now it's up to about 18 mpg mixed (75% highway/25% city). I purposefully use cruise control at 68-70 mph on the highway though.

Stickshift mileage???

I am curious about the H3 stickshift. Every stick I've ever owned always made the EPA estimate and bested the HIGHWAY estimate.

Is this true for you manual owners? Can you best 21HWY... especially on long road trips?

Thanks

RE: Stickshift mileage???

I am getting about 16mpg to 16.5mpg so far, so probably a bit over 16 an average..... I thought it was bad but I see I was mistake :/

RE: Stickshift mileage???

Only been through about three tanks, but about 15 1/2 city and 16 1/2 on the road.

You guys realize that by installing this kit ur voiding your warranty on the H3 ? not sure if all or on the engine itself. This is what my dealer told me.

Hello all,

I'm new here but as a self-proclaimed car guy, I've been around the block enough to know that your dealer is lying to you. Your dealer cannot void the warranty unless he can prove that the aftermarket part caused the issue. Sounds like he wants to charge you to install the part himself. Intakes and such are pretty straight forward in terms of installation. Here's a link to the legal Mumbo Jumbo:

Magnuson Moss Act

Tell him you know better or find another dealer. My 0.02.

I just asked him if it voids the warranty if I get one, I never said I would. He went to the parts guys or whoever deals with this stuff. if I did buy it I would probably go and isntall it there anyways. He did not say anything about bringing it there, just that it will void warranty once installed. And once you install it and something goes wrong with the engine, they can always say it was your messing with it that caused it, and it is more your problem to prove otherwise then theirs to prove anything

um... no. I'll make it easier for you.

US Code - Title 15, Chapter 50, Sections 2301-2312

Legally, a vehicle manufacturer cannot void the warranty on a vehicle due to an aftermarket part unless they can prove that the aftermarket part caused or contributed to the failure in the vehicle (per the Magnuson Moss Warranty Act (15 U.S.C. 2302(C)

Regardless of what he says or the assumtions you are making, they cannot void your warranty if you have an aftermarket modification. Now, if you go out and suck a bunch of water into the intake and you hydrolock the engine, that is your fault - but I'm sure you could do that with the stock intake as well - take your H3 through several feet of water and let us know what the dealer says about a fried computer or locked up engine.

An intake and exhaust are minor modifications at best- little power gains = little risk. Sure, throw the bottle and a cam on a car, have a problem, and you are on your own - but that's the risk you take with aggressive modifications. But even then the modification has to be related to the issue and if it is, oh well... you knew that going in. The law is the law despite what they are telling you. If you want to overpay for the same part and then get raped on installation, go for it. They'd be glad to charge you $75.00 an hour to drop in a K&N filter. Maybe the extra money can be justified as insurance in the very slim chance an airfiler will cause a catastophic engine failure. I say no - I don't buy extended warrantys at Best Buy either. My other cars are modded and the dealers never say a word regarding warranty - but in the event they do I know my rights and if it is related to the part in question, then I'm willing to take the hit. Trust me, they just want your money but if you want, be safe, leave it stock and you know there will be no future warranty issues. My 0.02

Thanks for the info, I will be advised :)

That's BS..I looked a new H3 in New Mexico and the Dealer installed a Cold air Intake, Dual exhaust and CHIP programmed the engine and all was still fully under WARRANTY..No problems[sm=trust_me.gif]i

Just an Idea..

I haven't read all the threads on this subject..But at least let the car go over 2000 miles before you start tracking the Mileage..The drivetrain is still new and stiff to get anything accurate measure with less miles.

I am getting right about 17 mpg maybe 16.8

also i added the K&n intake kit, I have noticed more power , but not more ,pg,, probably because i drive more aggressively

2006 Black H3 with Luxury and Adventure Package.

a whopping 12.8 mpg. first tank though and all stop and go. I assume they have the speedo programmed correctly for the 33s on the adv package.

13.5 mpg. (city) average, and I'm getting about 17 mpg. highway, I have mine since July '05.

I've driven 2100 miles in mine and it's averaging 15 in mixed traffic and 16 on the hwy. I'm pretty careful w/ my driving habits... ie, I don't rabbit off the line and accelerate smoothly.
That's about what I got in my '03 Tahoe Z71 w/ the V8!
I love the styling, the ride, the handling, even the interior... Everything IMO was done perfectly except the marginally adequate engine that also gets bad gas mileage. Is it the 33" tires on the Adv Pkg that hurts the mileage perhaps?

JUST TURNED 3000 MILES AND 1ST OIL CHANGE, WITH AUTOMATIC AVG MPG IS 16.5, AT THIS POINT.HOPE IT WILL GET A BIT BETTER -- SOME HAVE GOTTEN 20 ON HIGHWAY AFTER 6K MILES. THOUGHTS?

I checked this carefully the other day and I am getting 13.5 with a 50/50 mix of hghway / city...

18.3MPG...Light footing it around town..Oil has been change at 1000 miles, the ODO now has 1800 miles.
