#79 of 174 Fuel Economy Sucks!!!!
Mar 30, 2008 (11:31 am)
I bought a 2008 Matrix TRD with automatic and the fuel economy sucks. It has 2417 KM or 1510.6 Miles on it and it is averaging 29.5 miles per gallon (thats 23.6 miles per gallon for you US folks) driving 50/50 city/highway. It is averaging 32 miles per gallon (25.6 miles per gallon US) on highway only driving. It is the worst car I have ever owned for fuel economy and I have owned quite a few cars including Acura Integras, Tercel SR5 4x4, Honda Accords, Mazda MX-3, Chevy Cavaliers, etc. In fact the only vehicle that I have ever owned that got worse gas mileage was a Dodge Grand Caravan with a 3.3 liter engine and it averaged 30 miles per gallon (24 miles per gallon US) driving mostly highway but not all and with 5 adults and a lot of luggage in it, thats only 2 miles per gallon worse than the Matrix with no luggage and only 2 adults sitting in it. The EPA on the matrix is 34 city (27 US) and 45 highway (36 US) but it is not even close to that.
Before you think it is just me here are a few facts to concider. Every vehicle that I have owned I have gotten almost exactly what the EPA rating is except this one. When I was at the Toyota dealer I talked to an elderly lady who had a 2006 Matrix auto with 104,000 Km (65,000 miles) on it and she said she has averaged 30 miles per gallon since she perchased it. That's a whole half a mile per gallon more than I am getting.
I also went the local car rental company and talked to an employee who owns a Matrix with a 5 speed manual with 60,000 Km (37,500 Miles) and he said he is averaging 35 miles per gallon (28 miles er gallon US) driving highway only. Thats 3 miles per gallon better than I am getting with an automatic and a car that isn't broken in yet. Sounds pretty close to what I am getting considering the differences.
Driving the exact same highway with my old 1988 Acura Integra I would get 45 miles per gallon (36 miles/gallon US) not 32 (25.6 US) and that car would eat this one for breakfast anytime anywhere.
I have gone to the dealer to have it checked out and they say that there is nothing they can do to improve fuel economy. They also said that if the check engine light isn't on it will not pull any codes on the diagnostic computer and without a code there is nothing they can do. I bought this lemon because of its claimed fuel economy and it sucks. I have contacted Toyota Canada and started a claim but will have to wait for 10 business days for a representative to contact me. We will see what they will do.

09 Matrix base model (automatic) been getting 28-29 mpg with maybe 60% city driving and 40% highway driving.. only had it for 1300 miles so far though. Have a few coworkers with the vibe and matrix previous year models and they all get decent gas mileage for the way they drive theirs. I don't drive like a maniac.. lol
We are switching over to the summer blend for gas so the mileage may be slightly better.

Congratulations on your new ride. This is great news - better mileage than EPA sticker, even before break-in period.

best fill-up in a while today: 379 miles, 10.0 gallons, so about 38 mpg. Good stuff!
'07 XR 5 speed.

I also had my best fill-up in a long time (since winter started). I got a little over 36 mpg. It was the warmest week we've had so far and I'm hoping it continues to go up.
#84 of 174 Gas Mileage Improved !!

I would like to update the message l left on March 30/08 (Gas Mileage Sucks !!!!) Maybe someone can help me out with this.
Since I wrote that message in which I had be averaging 32 mpg (25.6 mpg US) on highway driving I changed gas stations. The gas station I used up to the point I posted that message was always the same gas station (Extra Foods Gas Bar). Since then I have used a different gas station (Co-op) but always the same one as well. The difference is almost unbelievable.
The car has now been averaging just over 40 mpg (32mpg US) on 3 different highway trips. That's a 25% improvement in mileage just by changing gas stations everything else is the same (driving same speed, same highway, same number of people ect.)
Hummm makes me wonder what the difference is. Could it be incorrect pump calibrations, bad fuel, or fuel that doesn't run well on this toyota? or maybe some combination of them?
Does anybody have any thoughts or has anybody else had results like this?
I think at some point I will try Extra Foods Gas Bar again just to double check.

"Could it be incorrect pump calibrations"
Yes, it could, and this is why I avoid cash'n'gas places. If this was the cause, you were getting ripped off every time you bought gas there (you were paying for more gas than you actually got) - I wouldn't recommend going back there for any reason.
A few stations every year face charges and pay huge fines for bilking customers in just this way, and enforcement in this area is woefully understaffed, so for every one prosecuted there are probably hundreds getting away with it all the time.

Didn't the Today show have a thing on this a while ago? They say to pump the gas a slow a possible. This helps get the right amount. The faster you pump the less fuel per gallon you get. Then, I think they said if it is above 80 degrees you get less fuel per gallon. So they said it is better to fill up at night or when the temp is below 80 degrees.

"Then, I think they said if it is above 80 degrees you get less fuel per gallon. So they said it is better to fill up at night or when the temp is below 80 degrees."
One of the car mags recently had an article on this, and it is a myth. The reason it is a myth is that temperatures in the tank, which is the temperature governing the volume of gas you are getting, is very constant because it is underground.
Now I DID see one of those news magazines recently (was it 60 Minutes? I'm not sure, but it was one like that) on the whole issue of these stations knowingly overcharging for their gas by rigging the pumps, which is where that information came from that I posted.

I talked to a rep from Toyota Canada about my poor gas mileage and he was very helpful. He told me that I could bring in my car to the local dealer and have it checked (under warantee) because if it is getting bad fuel economy than that is a warrantee item. He also said the dealers have ways of checking the fuel milage the car is getting and would be happy to do so for me (at no cost). He acutally phoned the dealer of my choice and told the service manager to look after me regarding these two items. The fact that Toyota stands behind their products this well is awesome and is great news for Toyota owners.
I also talked to him about my findings with changing gas stations and posed the question to him about bad fuel and/or fuel with the wrong type of additive in it that may not work well in this car. He told me that any unleaded fuel from any gas station should be fine. As far as any additives in the fuels he thought that running up to 25% ethanol in the fuel is fine (he wasn't sure but he thought it was 25%) and the fact that gas stations shouldn't be using more than 10% ethanal in their unlead fuel (depending on gas stations) it should be fine.
I found this interesting since ethanol (or ethyl alcohol) is produced by using a fermentation process of yeast and sugar to produce alcohol which is basically the same type of alcohol found in alcoholic beverages. Ethanol contains approx. 34% less energy per unit volume than gasoline, and therefore in theory, burning pure ethanol in a vehicle should result in a 34% reduction in miles per gallon, given the same fuel economy, compared to burning pure gasoline.
Therefore, I would have to asume that the more ethanol that is added to the gasoline the worse the gas milage would be using that fuel. In other words if 10% ethanol was added you would expect to get 3.4% worse fuel economy (10% of 34%) than gasoline with no ethanol.
This would mean that bad fuel or fuel additives could only account for 1-2 mpg difference in fuel economy not the 25% difference I noticed. It would now seem most likely that the cause of the huge difference is incorrect pump calibrations.
Obviously more checking is needed in my cause but I found this information very interesting.
