New 2013 Prius C, poor MPG

welcome to priuschat! miles per tank means nothing since tanks come in different sizes. to help you with mpg, fill out the sticky on 'why am i geeting such low mpg' and that will help us diagnose your problems. more than likely, it's the way you drive, low tyre pressure and the cold climate you live in. all the best!

 

I am getting 420, its all in the way you drive it.

 

Are you driving until the tank is empty or filling up when the gas gauge is 'low'I typically fill up when I'm down to 1 bar on my gauge, or when the yellow light comes on, knowing I still have at least 1.5 gallons left. You also didn't provide any details on how you drive or if you let the ICE warm up in the morning, etc. Your Corolla had a larger gas tank than your C too. I could regularly get over 500 miles/tank in my previous Prius IV, and now regularly get 425 - 460 miles/tank in my v.

 

click on the forums tab, scroll down to GEN II and click on fuel economy. it's the last sticky by member cwerdna. and there are other helpful ones as well. these were all developed in the pioneering stages of the prius.

 

ICE = internal combustion engine. You don't need to let it warm up, except for maybe 30 sec or so, or if you have scrape off snow or ice. Generally, I always get in, buckle up, press the power button, wait a few seconds for the 'Ready' light to come then shift into reverse to back out of the garage. By the time I've backed out, the ICE starts up and basically 'idles' while I coast down the driveway and drive up to the stop sign at the corner. By then about a minute has gone by so the ICE is warmed up enough for an easy drive to the community gate, about a mile.

 

Huh? Yeah...but ALL commercial Prius c's do have the same size tank.

You can evaluate what type of mileage you are getting in comparison to miles per tank. Infact if you're hand calculating your mileage that's what you are doing. It's hardly "nothing". How much fuel your putting in every time you fill will vary, but I know I pay attention to how many miles I'm averaging per tankful.

 

op compared it to his corolla, not another c.

 

The OP mentioned his Corolla but still was commenting on his miles per tank on his Prius c. As in "I'm only getting 350 Miles Per Tank On My Prius C".

Your statement that "Miles Per Tank Mean Nothing"...is false. The only way to really gauge your true gas mileage IS by paying attention to your miles per tank. Coupled of course with how much you are putting in your tank per fill up.

I think the whole reason the OP posted, was to get feedback about Miles per Tank in comparison to other Prius c owners. All of which SHOULD have the same size tanks.

Yes...A Corolla and a Prius c probably don't have the same size tanks. But that doesn't mean Miles Per Tank mean Nothing. It only means that the comparison between Miles per tank of the Corolla and Miles per tank of the Prius c....is comparing Oranges to Apples. But again, I think the OP knew that..and IS looking for a comparison from other Prius c owners.

 

really? i just divide miles by gallons pumped.

 

Most people...adopt a routine as far as when they fill up.
So the fills are usually pretty consistent.

Plus OF COURSE you divide miles by gallons pumped...which is why I said:

"The only way to really gauge your true gas mileage IS by paying attention to your miles per tank. Coupled of course with how much you are putting in your tank per fill up."

 

it seems silly to me, and potentially dangerous, to run your tank out of fuel just to see how far you can go.

 

Are you purposely being dense?
When or where am I or anyone saying run your tank out of fuel just to see how far you can go?

 

how else do you determine miles per tank? otherwise, you're going to get a different reading each time you refill. you cannot know the exact amount left in the tank if you don't, and you cannot know the amount after you fill. (unless you fill to the very top where you can actually see it.)
