My 2018 Prius Three is draining gas FAST

Or a fill - preferably at a different fuel depot.

ANOTHER THOUGHT:

When you stop, I assume you POWER OFF? Probably - otherwise you can't lock the car - but if you put it in a secure garage and don't turn it off, the A/C will run all night.

 

I'd have thought that was inconsistent with "... giving me scores of 77-93 ECO driving and saying I'm reaching 80 MPG." But if those scores are just for trip segments, not a whole tank, then this possibility must be checked out.

 

That's what I thought too - but worth checking out.

 

If each of your “fill ups” cost you between $20 and $30 then we are speaking the same language.

If not, then we need to define terms.

 

Just a thought here.

California is a weird state - they ban everything. But is Ethanol available there? The pumps where I live here are now showing up with 2 nozzle heads. One of which is pure ethanol, the other is 15% or 10% ethanol. The only difference is the color of the handle. I nearly put pure ethanol into it on my last fill up.

Could she be burning 100% ethanol? I don't know if it would set a code, but i've seen it done around here on other vehicles and nobody I know has ever had a car throw a code. But they do get very hard to start if the car is warm.

Like I said, just a thought...

 

You're right about it being weird. (Blame it on the politicians.)
But about the gas, I have never seen a 100% ethanol pump. We only have 10% pumps at the major gas stations.

 

We've had 100% Ethanol pumps here for quite awhile, but they were always a "single pump" out there by the Diesel. But now, the Diesel and Ethanol pump's are being combined into all the pump's at the station. The 10% mix has been here for awhile obviously, but that's kinda changing with the 15% blend at the pumps now. We even have one station here that doesn't offer 10%.

There is a picture here on PriusChat of the type of pump I'm talking about - kinda confusing at first. I'll go see if I can find it and come back and "edit" my post to show it.

{edited with the pic} Also, sidenote: When I say 100% ethanol I'm referring to the "Flex-Fuel" stuff - which if you want to be technical is like 85% ethanol I think.

Yes, I think I saw that picture. Some of our gas stations have a "two nozzle" pump. One for diesel / one for regular gas.
Other stations have a serarate diesel pump.

 

How did you drive your last car? When did you get gas?

I would suggest just driving your Prius like a normal car. Quit looking at all those Eco displays, ignore those silly "scores", quit looking at the trip logs, no need to chart anything.... Just drive it! Why do people want to make a Prius so damn complicated?!

Forget the car's mpg computers. Mine are all over the map! The only way to figure out your TRUE gas mileage, is to calculate it by hand... after you fill up... and use your cell phone calculator. Simple!

 

That's insane! Let's all start riding bikes!

 

I've seen cars with the FlexFuel badge in NJ, but there's no place here to fuel them, unless you want to drive all over the state.

 

As far as I know, there were only 2 cars sold in Australia which took E85 (ie 85% Ethanol) - Holden (GM) on the Commodore from about 2011 for about 3 or 4 years, and, SAAB had it a few years available, but I think as an option. That said - fuel stations which supplied E85 were rare.

 

"Unleaded 15" infers 15% ethanol? Very vague, and why say unleaded: they're all unleaded. The proximity of these higher ethanol pumps with regular, coupled with the cavalier labeling, is gonna make for a lot of engine damage.

 

Brother, you can say that again!

70% of the people here.... "no speak eeenglish."

(now somebody go teach Chime how to drive her Prius.)

 

I am offended by YOUR post.
Giving bad or incomplete advice is not "empathisizing".

What I said is exactly true.
Going to the dealer and saying "I think it's using too much gas." will likely be a total waste of time.

That is important information and saying it plainly and simply is not "shooting from the hip".

 

No it won't.

Most vehicles made in the last 20 years or so will do just fine with E15.
Especially if you only put in a half a tank or so mixed with E10 or E0 once in a while.

It is not the actual "engine" that is damaged anyway. It is things like hoses and seals.

NOW......if you are driving something that qualifies as an "antique" (most anything that has carbs), then you should be hyper-sensitive to this issue and if you make a mistake, it's on YOU.

 

You're cherrypicking from my post: the E85 is right there too, on the same pump.

 

I think this entire thread is Fake News! Chime just needs to read the owner's manual.

 

When you are trying to prove (or determine) that there is a problem, you absolutely DO.

But it's not that complicated.
Reset one trip Odometer when you fill up.
At the next fillup, record the gallons put in and the mileage on the ODO. Do the math.
At the second fillup, add the gallons from the first one and do that math on the ODO.

 

E85 has been around for 10 years or more.
And there has not been "a lot of engine damage".
