Am I doing the math wrong or did I just get 40 something miles to the gallon? Topped it off when I left the lot drove 450 miles and put in 11.3 gallons.

To get your gas mileage fill your tank all the way up. Keep track of how many miles you drive. Normally this can be done by setting your Tripometer at zero. Next time you gas up fill up all the way. Take your miles driven on your tripometer and divide it by the gallons of gas you put in the tank. You'll then have a idea of your MPG.

Hey LULU, what are yo udriving? I have the GT and just got 31 MPG and that wasn't while trying to conserve gas. So, you very well could have!

I'm averaging 12.5-14.5 km/l, with a high(straight hwy) of 15.6 km/l.1mile=1.6km you do the math.

I have 7000 kilo,s (4340) miles on my base 5 speed Vibe. My best mileage has been 40 mpg( Canadian gallon) all hi-way at 70 mph. This is about 32 per US gallon.

I've been getting 19 mpg with all city driving and the A/C on. Plus I have a heavy foot. That's about 1-mph better than my '93 Sunbird got. I expect to get a little over 20-mpg once the motor loosens up.

Wow!! At 6.4l/100kmm that's 44mpg!!! That is actually better mileage than the Honda Civic Hybrid and The Toyota Prius. That's even better than the Golf TDI. Almost unbeleivable! Unless there is a conversion factor I'm not getting. 1 litre = 4.54609 gallons, right?I'm getting about 9.8l/100km. with my GT. That is with about 80% city and 20% highway. IT's getting better with every tank. I have 5000 kms.Ryan

See http://oee.nrcan.gc.ca/autosmart/fcg/20 ... nGuide.pdf {acrobat required}The toyota and honda will get around 4.5 city and 4.7 highway (the honda isn't listed but I saw somewhere the results were similar). The VW TDI's get 5.6 city and 4.4 highway. The Vibe is very efficient but not in their league. On the other hand don't ask those cars to pull a camper or a jetski.

I was using the numbers Motor Trend got in their last issue. They did an article on both hybrids and there was a small side note on the Golf TDI. In their real world tests (not the epa's) they managed 43 mpg if I remember correctly. You could imagine why I was surprised at those numbers compared to what he got with his Vibe!Ryan
[Modified by Ryan, 12:29 PM 7/30/2002]

American Gallons are smaller than Imperial. Multiply mileage figures from american mags by 1.2 to get the mpg we are used to. So 43 x 1.2 = 51 which sounds low to me as the transport canada sez 64 MPG for a TDI. I don't imagine Motor trend was easy on the throttle on their example.

i have been drivin my GT since the end of march, and i am a loon when it comes to seeing what my gas mileage is. i always reset the trip A on every gas stop, and trip B on every other. I drove it from Florida to Michigan, all freeway driving at 75mph for a full tank, now that means that the engine in overdrive should be running as efficiently as possible, and at BEST, i only was able to get 33.6mpg (us gallons) this figure was repeated to be around 33.5 on highway consistently. I know many of you are thinkin but what about AC, well quite frankly since its not all that great in the Vibes anyway, and it really screws with my sinuses, i dont use it ever. im a strick 4/70 man. 4 windows down, 70mph keeps the car nice and cool.yogi

quote:Wow, I didn't think a Vibe would get that kind of milage! The good news just keeps on rolling!!I consider the Vibe to be quite efficient. It gets better mileage than the Protege 5, Focus and Subaru wagons that I compared it to. I didn't consider the TDI because of the hauling and camping I plan to do.

I have 10k miles on my Vibe GT. Mostly Interstate miles, all 92octane gas. I am getting 30.2MPG.

I've kept track on the last 3 fill-ups for my Vibe GT. I have not tried to influence the mileage at all. One was a 325 mile trip with a fully loaded car, the return trip with half the load gone, and regular town driving. All three have resulted in 30 mpg. (By the way, I have a lead foot and can't resist either running through the gears or the "lift" at 6500 rpm) Compared to the 21 mpg I use to get with my Mustang - I'm ecstatic! Just a quick update. I started playing around in the "lift" section of the RPMs and there was a distinct difference in my gas mileage. Both fill-ups during that time period came back around 23 mpg. After that, I purposely stayed away from the 6000rpm range and the next fillup my mileage was back at 30 mpg. I guess that's the price we pay for the extra "fun".

I've already posted this in the general discussion group, but I think this forum is a more appropriate place for this post.I got my Vibe (base, automatic) on July 20/02 and after returning from my vacation, I've driven over 4,000 km. since the purchase. Perhaps you're interested in my fuel economy between my fill-ups (converted to mpg):25.68 (mainly city driving)30.67 (mainly city driving)33.84 (mainly highway driving)38.43 (100% highway driving)28.86 (highway, country roads)29.44 (higway, country roads)38.56 (100% highway driving)24.44 (80% city driving)By the way, I quickly wrote a conversion program on my Excel--I hope I do get correct figures--for example, 10 liters per 100 km. equals to 23.52 miles per gallon.One more thing.... according to the Vibe's specifications, my fuel tank holds 50 liters. I was quite surprised when I managed to buy 50.102 liters and I even enquired about this here. Last time--at a different gas station--I bought 52.075 litres--and of course, my tank was not completely empty. So, I wonder how much gas would my tank hold if I ran out of gas?

Makes you wonder about those curbside bandits. If they are charging you for 52 litres and giving you 50 or 49 that would be one way to make a couple of extra bucks. Reminds me of the matchbook or toothpick people that short everyone 1 or 2 and make up another box every so often with ones they hold back.Take a jerry can with you some time and see how much they say you can put in.

Well, I think the tank must be bigger than 50 liters. After all, I'm buying gas at well-known companies and despite all the business scandals and frauds we so often hear about these days, I can't belive gas companies would so openly cheat us. I wonder if other users have had similar experiences? By the way, my Corolla also has a 50 liter tank and in my 9 years of owning it, my fill-up 'record' was 46 liters.

quote:I can't belive gas companies would so openly cheat us.Sorry to burst your bubble. We can travel 3-4 hours and find fuel 10 20% cheaper in the same jurisdiction (same taxes). The gas stations all monitor each other's prices and stay within $.02 per litre of each other. Once in a while the public get's pissed at them, the government investigates and mysteriously the prices go down. No collusion? You decide.Wouldn't suprise me if they short us a litre or two.

Hi Jack!Did you ever heard about "AUTOMATIC TEMPERATURE COMPENSATION" ? A lot of gas station in Canada uses this equipment on their pumps and this is legal. The volume of gas that you buy is referred to a 15°C temperature. It is not a good thing for consumers... A few years ago, when gas stations didn't have it, in winter, we were able to have more fuel than in summer for the same price !!!! I believe that is the explanation of your problem...You can find more information there: http://strategis.ic.gc.ca/SSG/1/lm01094e.html or http://strategis.ic.gc.ca/SSGF/1/lm01094f.html Bye !

So far after 6 fill ups and 2200 miles (in Two weeks, Thank god I didn't lease) I'm averaging 30 mpg. Mostly highway miles at about 80-85 MPH. IF I slow down to 70-75 will this improve my mileage figures, or can I go as fast as I want? I have a base vibe auto.

The faster you go the more HP the engine has to make to over come wind resistance. Your using alot more fuel to stay constant at 80 to 85 MPH than you would if you were to drive 60 to 70. Plus your RPMs are higher up the RPM band the faster you go meaning the engine is using more fuel. (more power strokes) This isn't good to do on the highway or interstate but I have read serval places the best gas mileage speed is 40 mph. After that the vehicle starts really pushing against the air.

quote:This isn't good to do on the highway or interstate but I have read serval places the best gas mileage speed is 40 mph. After that the vehicle starts really pushing against the air. I've read in mid 80s that BMW did a test. to get best mileage: to upshift at 2000rpm, with full throttle and lug the engine. this gives maximum efficiency. don't know if this is true anymore.

Generally low RPM lugging is best for economy (but feels awful), as for example Corvettes with the infamous "CAGS" (Computer Aided Gear Shift), which forces you into 4th instead of second on a moderate RPM upshift. You end up at about 500 RPM in 4th! Also, in any fuel economy contest where it's legal, the contestants use full throttle in a very high gear up to about 15 -20 MPH, then shut off the engine, coast down to near-zero and dump the clutch to restart then repeat. Impratical for sure, but they can more than double normal driving economy!

I also have the base 5 speed with 6400KMS now. My last three tanks were 70%highway:36.5MPG41MPGNow this last tank is at 600KMS with a fulll 1/4 tank left, I should beat the 41 easily. I'm not embelishing here either, these a pretty accurate calcs. (Canadian gallon used)quote:I have 7000 kilo,s (4340) miles on my base 5 speed Vibe. My best mileage has been 40 mpg( Canadian gallon) all hi-way at 70 mph. This is about 32 per US gallon.

I have a base vibe auto.Most cars (yes, CARS, not SUVs) typically obtain their best gas mileage betwen 50-55 MPH (approx 81-89 Kph). Anything above or below that is going to cost you efficiency. But yes, if you slow down, you will improve your figures - to a point. Not sure by how much they reduce, but over a long period of time, it could add up. When you start going below 40mph, you're MPG ratings go back down again...more gas is used to do less work.Here's some science behind it if you're interested: How Stuff Works: Best Gas MileageBut life is short. Drive fast. It's more fun.

On a recent trip to the Twin Cities from sothern Wisconsin, I was at 39 MPG on the firts tank. All highway around 70 mph on the way there (390 miles). Then city driving for a while (40 miles). From my fill on the way out of town to the first fill was 430.9 miles according to my Trip A. I put 11 gallons in to the tank. The trick I found was to get behind a semi and sit 20-30 feet off his bumper. I was able to do that most of the way there which was about 390 miles of the 430.9 on my Trip A. Had I stopped and filled as soon as I got to St. Paul, I'm sure I would have been a little over 40 mpg. All in all I was quite impressed with both the Vibe's gas milage and it road manners at 70-75 mph.

Just got back from my vacation.Chicago, IL -> Lima, OH (drop off the dog at parents ) -> Jenson Beach, Fl and backHere are my stats for the trip8/08 - 08/18/2426 miles33.14 Average MPG346.57 Average Miles per tank.391 Max Miles per tank$144.35 Total spent on Gas$0.052 Cost per mile(info from FuelLog 1.0, A palm pilot program)I'm really happy with the milage that I am getting. The speeds were mainly 70-85 MPH with the Air on the whole time.

quote:Current running mileageLooking at your numbers its easy to see the correlation between gas mileage and what type of driving, the entries with more city have worse mpgs, which is what I'd expect. The effect of AC is harder to see though. Do you think that running the AC is having much effect on your mpg's?

I was always told that it wasn't much different because the drag from having the windows down was just as bad or worse than having the air on.

It seems like running the AC did hurt mileage, Except for the first entry, the only times he got over 30 was when there was little or no AC use. Also, installing the CAI doesn't seem to have had any noticeable effect on mpgs.

Heya NSimkins,Was looking at your mileage chart... ya know, I was in Ohio the weekend of Oct 25th and founf myself getting about 26 mpg but with about 75% highway driving. I had seen someone's graph where it seemed their mileage fluctuated high to low every other fuel-up. I've found that to be true as well but wasn't too happy about the 25.6 mpg I got while in Ohio (Dayton area). I'll get a 33 then a 27 then a 32 then a 29... up down up downI know there was a posting about different gas brands and such a while ago but I swear I get better gas mileage at certain stations like Marathon (No Ethanol added) and occasionally a Cit-Go if the octane is 92-93. Do you notice mpg differences from different stations and/or different octanes? I'm not talking performance differences as much as the mpg.Dave

quote:Do you notice mpg differences from different stations and/or different octanes? I'm not talking performance differences as much as the mpg.Personally I haven't noticed any differences in gas mileage between gas station facilities. The only difference I can tell and prove is with the type of driving I do (highway vs. city) and how hard I push it during that period.

Just to throw a monkey wrench in the works, I want to put in Arnold's $0.02.Here in Cali we have gas with ethanol in it. This is known as partially oxygenated gasoline. What that means is that the oil companies and the government have been kind enough to burn some of it for you before you've even pumped it!Moving from NYC to Cali, my Vibe took a 3 mpg hit. Putting on the wide sticky tires cost me another 1-2 mpg. In about 50/50 driving I get between 24-26 mpCAg. Oh and another thing, there is no pump gas over 91 octane anywhere in the whole state! All of this is not to mention the $2.10/g that premium is averaging. I know it's worse up north, but are you Canooks having your registration fees triple this year? Ahhhh, the wonders of deregulated utilities?!?!?!?-Burt

I think in Illinois we're supposed to have the Ethanol, at least that's what I had heard. I'm surprised to find a station without it. This station is actually attached to a Truck Stop. I'm a bit concerned that they don't have enough Premium customers and I'll start getting older gas (My car dealer suggested I get gas from a place that sells a lot). 93 octane, No Ethanol added... I get good mileage from there with my 235/45R17 tires... Still 26/C 30-32/H but it is starting to go down due to the colder weather. Oh, and the gass here is down to about $1.56 for Premium, YAYDave

I believe there are some Vibe that are out of spec, it seems 1/2 of the people here gets over 30mpg, 1/2 can't even get to 28mpg.No, I drive the same on all of my cars. My Venture minivan (rated 18mpg in the city) gets 22mpg. I have always been able to get at least EPA rated for the city. The best I ever got was driving from Las Vegas to Los Angeles, I got 28mpg !! with Vibe's EPA of 28 (base auto), I believe I should average around 30mpg or so. my buddy's 04 Corolla (same engine) gets 33mpg, and that's with me borrowing it for a week.May be a bad oxygen sensor or something, this is driving me nuts, I am thinking of selling my Vibe just because of the horrible mileage it is getting.

We have oxygenated gas in the winter months I think. Or it's only certain times of year anyway.I don't typically get EPA ratings, but I know for a fact it's the way I drive -- very hard.

I consistantly get between 25 and 30mpg in my auto Matrix XR. the most I've seen is 33mpg on a 400 mile trip, all highway no AC or defroster. The EPA ratings are really for comparison purposes only. I think once I swap a 6-speed manual transmission onto my car the highway mileage should get better.--Matt

I find that consisently get about 32 mpg, but I generaly drive pretty conservatively. I try to keep the RPM's below 2k till its warmed up and then try to generally keep the car under about 3.5k RPM's unless I need to pass someone, or jump onto the freeway (why do people insist on merging onto freeways at 45-50 MPH. The entrance ramp is made to get up to highway speeds). When the weather turns cold, I loose about 1-2 MPG, but I expect that. Here in Illinois we have up to 10% ethenal in our gas all year round. I haven't noticed any difference while driving to Florida last August with the different gasses, except that Amoco, Shell, Phillips 66 and Exxon give the best consistent MPG.

I bought my '03 VibeGT -- got an envy green one before they stopped that color, and love it -- in August of '02. Mostly I was getting 31 or 32 mpg in mixed driving and on early trips.But I did a long trip last summer from Pittsburgh to British Columbia and back. Over 5500 miles under a wide variety of conditions, I was getting 32.5 to 38.5 mpg regularly. Now that includes mountains (Glacier Nat. Park), prarie, expressways, overland, as hot at 106F and as cool as 45F, but pretty much moving, not stop and go.I always set TripA with a new tank of gas, and TripB at oil change. I drive pretty conservatively, especially on a long trip like that, but used the power if I had to. I was camping at Nat. Parks -- fold down the back and front seats, fold out a 5 1/2 foot plywood and cushions to cover it. I'm over 6' 2", and sleep very comfy in the Vibe -- although getting in and out takes a little agility.Anyway, middle thirties is possible on a long trip if you drive with a thought about mileage.

I'm with trdvibe. 24-28 and I have 80% highway. Hard to keep out of lift when I'm leaving those toll gates. EPA highway milage for a GT is 32 and thats done following speed limits. Where I drive, I would be disrupting flow by doing 55. I doubt anyone will ever see 38 mpg in a GT. I remember in another thread some folks were getting their mileage #s by casual figuring instead of topping off a few times on 300mi or so runs. I'm thinking that thin hot moutain air could get some good mileage with a corresponding decrease in power but 38mpg seems high unless it's mostly downhill.

I have the Base Vibe equipped with the automatic and live in Michigan. I checked millage on one tank full when I knew all but about thirty minutes of the driving would be on the expressway. I babied it, rarely ever going over sixty miles per hour, in an attempt to see the best millage I could. As you know, it's difficult doing only sixty, watching all those cars fly by, but I stuck it out for just this one time. This was in the middle of summer and the weather was perfect. When it was over, my millage came to 34.04 MPG - kind of disappointing considering the speed I was going, but it sure beats my Grand Prix.

That's 1 mpg better than the EPA #. I wouldn't be dissapointed at all. That's about what a best case should get you.

My in town mi. seems to have gown down a little since I put in the CAI. About 26 instead of 28. Highway is still above 30-33 at 70-80 mph. More power and more fuel used when driving in town. Still worth it! I just went on a 5 hr. trip at 80-85 mph and still got 30 mpg.

I've gotten 36 in a GT on my trip from Illinois to Florida . Not quite 38, but close.

Welcome to genvibe, not many envy vibes around. glad you signed up!Quote, originally posted by tnehrer »Anyway, middle thirties is possible on a long trip if you drive with a thought about mileage.My driving habits and traffic really affect my mileage. So far my worst mileage tank of gas was the one just before christmas, lots of stop and go traffic trying to do too much last minute shopping, cars clogging all the roads, short temper, no patience, aggressive driving, I was guilty of all the things that bother me in other drivers. no season of peace and love for me when time was running out and all those people were in my way. Had a dramatic negative impact on mileage.

Had my vibe 5 speed for a year now, didn't keep track of mileage for the first couple of tanks, but have since then. I didn't keep track of percentage highway/city or AC use like Nick does on the first page of this thread. I keep a spreadsheet and it calculates the per tank mpg and overall average mpg. It think it's important to average several tanks to get a good feel for how it's doing to reduce the effect of how full the tank gets filled each time. I need to come up with a third line that does a shorter term average so that any seasonal trends might show up. The effect of christmas shopping shows up. The dates/mileage are when I filled up, shows the average since the previous fill up. Anyway, here's my first year's gas mileage data. lY axis units are US miles per gallon, x axis is US miles on odometer

After seeing joatmon's graph, I was inspired to post my own data.I've been using Fuel Log on my Palm Pilot to keep track of every fill since I got my new catalytic converter (May 2003).To date, my average MPG (US) is 28.43 or 8.27 L/100 km. In the summer, it goes down to about 7.5 L/100 km (32 MPG).
