Prius (2010-12) Fuel :: Is Computer Programmed For 0% Ethanol Or E10
Jul 13, 2010
I've recently had the chance to buy some 'real gas' on a few fill-ups, Canadian gas without ethanol. The graphic shows that I'm getting about 50 mpg on regular E10, but about 58 mpg on the no-ethanol gas. Since E0 has only about 4% less energy than regular E10, getting 15% better mileage doesn't make sense purely from thermodynamics.
Does the Prius computer might be programmed for E0, and therefore possibly doesn't do as well on E10? And if so, can we re-program the computer?

For each number the computer says is there an exact match to what it means for computed. For example if the computer says 50mpg does that always calculate to x number calculated????

I've recently purchased a 2007 Prius and have been tracking my gas mileage. I've been comparing what the computer says and what I get by dividing the miles since last fill w/ the number of gallons to fill. I always reset the computer and have always let the tank get almost empty (flashing fuel gauge). I consistantly calculate 2-4 MPG LESS than the computer reports. I talked with a friend who has a (I think) 2006 Prius and he does the same but his calculations and the computer usually within a few tenths of a MPG. I took my car into the dealer today for the accelerator pedal recall and asked them to look at the MPG. They could find nothing wrong and said that was "normal" I'm not convinced... What do the rest of you see?

My on-board computer is consistently telling me 75-99 MPG on trips (usually 10 to 20 mile trips). Obviously that's wrong. Could this be a sign that some system in my car is faulty? Should I get it checked out at the dealer? I don't really care if the computer estimates are off, but am just worried that it could be a signal of something worse.

I brought my 2012 Prius in on St. Patrick's Day for routine scheduled maintenance and was informed about the recall--I hadn't even known yet. I was told it would just take an additional 45 minutes for the software update--no big deal. Except that it was.
They said the computer that was hooked up to my car crashed during the update, and my car computer would no longer recognize the hybrid system. They had no explanation for the crash and said their computer had a full battery, etc. so it didn't make sense, but they would call Toyota to find out way to do and in the meanwhile I would have a rental.
It is April 7 and I still have the rental. They said the part needed, a new computer, is on backorder. They hope it will be in by the end of April but there are no guarantees.

How accurate is the calculation from the car's "computer" for the cruising range left?
In my experience from my previous vehicle. When my gas light would come on, I believe it generally meant that I had 2 gallons left in the tank before stranded.

So got this P0A93 code when I was driving on the highway about 65mph, scared to me death when big yellow warning light came on so I returned home and turn the car back on after 30 mins the code and all the warning lights were gone I checked under the hood felt the pump everything was good. I just got done 90k maintance on the car from dealer. So my question is that could be computer error or it could be water pump malfunction? On warranty manual the warranty for inverter with converter covers under 100k so dealer should be able to cover the water pump if it's broken? I driven the car today again at normal temperature and full blast AC on, then again no engine check light on and warning light no message.

I had my wallet and key stolen and my spare has somehow gone missing too. A dealership has quoted me half hour to program and an hour and half to reseed.
One of the things I was told is I need the reseed to cancel any previous fobs the car was programmed to. I don't care if the old fob is out there and could be used for my car. If this is the only reason for reseed I don't want it.
I am confused. Somewhere I think I read that if you don't have any keys then you'll need a reseed no matter what.
I had the black logo fob, not a proximity one.
Why a reseed needs to be done when you have no key to go off, or why you don't.

02 LSV8. 174k miles. Today it threw a Fuel Data Computer Error on the computer readout and the fuel gauge parked at E as if the engine was off. I am sure I have over 1/2 tank of gas.

As part of my 60 mile commute everyday to work and back, I would stop by a gas station in a town on my way home that has 30 cent cheaper gas than where I live. The first time I fueled the car there was no problem. Then today even though my gas was at 3/4 full and I stopped anyways to put in 5 dollars.
What happened next was strange, before I stopped to fuel my range was at 448 miles, with the needle exactly on the 3/4 mark, then I put in 5 bucks the needle did not move at all and my range was still at 448 even after I started driving back on the highway again hoping maybe it would reset. The needle then slowly went up but then the range didn't go any higher and was still decreasing as I kept on driving.
The thing different today was I accidentally put in Unleaded PLUS so it mixed with the 3/4 tank of just regular Unleaded gas..but as far as I know that shouldn't affect anything..right?

My 2003 Passat 1.8t starts up but turns off 1-2 secs later. And if it is the fuel pump, where is it on my car?

The computer apparently calculates the fuel economy per trip (or a series of trips if the car is stopped less than 2 hours) but I don't know how to get it to display the fuel economy for the tank full. Normally I'd reset the computer upon refilling but since it calculates per trip it doesn't calculate per tank. Fortunately the fuel gauge seems to be pretty accurate and each mark is approx 1 gal so I can do a quick approximation but I'm used to having the car do the tankful calculation. BTW, I reset on MFA 1, I've never reset on MFA 2 and that doesn't show tankful economy either.

I bought a 2013 XLT 4X4 wiht 5.0 V8 about 3 months ago. I reset the computer when I first bought it and it shows an average of 15.7 MPG. I have also kept records of all fuel purchased and my actual mileage is 15.2 MPG.

I'm the owner of a phaeton W12, i want to known if the engine can run with ethanol and with a kit. What are the risks for the fuel pumps, injection pump, injectors.

While most of the emphasis I've seen on improving fuel economy seems to focus on warming the car up quickly in cool/cold weather, I seem to be experiencing significant mpg drops at the other end of the spectrum.

I am new to the prius 2010.
I filled up last week and I noticed that as soon as a single cell display in the fuel display part has some empty section like 3/4 fuel(single cell) the next day or after that that whole cell disappears without it showing that single cell as being empty.
Around which fuel cell, when displayed, is it important and recommended to fill up gas again, with one cell remaining or two etc.

When I go out to do errands around town (I live right in town) I get horrendous gas mileage. Now, I understand gas mileage is high at the beginning of a trip, but for this long and this high and under these circumstances? I'm getting ABOVE 10l/100km when I have 80% charge available (for americans, that's disgustingly high MPG like, pick-up truck high), AND my foot is completely off the gas. Literally, coasting, or braking, and I'm still sucking up gas. What the heck?
Is this just because it takes a certain amount of time for the engine to run no matter what or something? I still don't see any reason for me to be eating up all that gas when my foot isn't even on the gas AND most importantly, I have charge available. Feels pointless for me to use my car for what I use it for 70% of the time, which is for quick errands around town at low speeds. Thought the prius was suppose to be a superstar for this kind of thing.

So my fuel light started blinking after 480 miles. How much more can I drive it? The display shows 30 miles left before fill up but I read in the manual that when the fuel light starts blinking there is 1.6 gallons left so should that be like 75 miles left. Just wondering. To be on the safe side, I went to fill up.

I was heading to the gas station with one bar on the fuel gauge. When I got there to fill up I had two bars, same Miles To Empty (45). What would cause that?

I just bought a used 2004 F-350, 4x4, crew cab, short bed, 6.0L diesel. I'm having a WTF moment on fuel. Gage indicates just under 1/4 of a tank of diesel but the on-board computer is flashing like crazy stating 5 miles to empty, what the hell is that all about?
