Hatchbacks Scion xA and xD Scion MPG-Real World Numbers

You are in the Scion xA and xD Forum. Your Host is claires
I've begun driving my 2009 xB with manual tranny on a 120 mile daily commute. 75% highway driving average speed 65 mph on the freeways, with some occasional stop and go (this is Washington DC area after all). I've been consistently getting 30-32 mpg, and this is with the AC on. It's not as good as my Corolla (which got nearly 40 mpg), but decent for a car this size.

| I found out long ago (I have 94K on my 2006 xA) that if you increase the air pressure your MPG will go up significantly. I am running 38 all around. I have my tires rotated and balance every 5k and I have 40K on the tires with no abnormal wear. Yes, the ride is more "bumpy", but you'll smile more at the pump!! | |
| New '09 xD automatic. First tank was 29 mixed driving. Several tanks later...latest mpg was 31+ with AC and 75+ highway speeds + city miles. | |

Replying to: joseph07 (Nov 18, 2009 11:52 pm) You really have to calculate mpg based on a number of fills-ups, not just one trip. Doing it for just one trip can be wildly inaccurate, because of variation in fill up technique, blends of gas, how the car sits, how fast you are driving that day, etc. Also, you may recall that many people here have mentioned that once little Scion engine gets over 65 mph, the gas mileage drops like a rock. So I'd say calculate at least 5-6 fillups and let us know how it's going. |

I have read your comment and thank you. Just to clarify, I drove in my ex's car to at least 4 different places this year and believe or not I calculated the amount of miles I got on each trip. From The Bronx to Washington, or to Pennsylvania, Virginia, Tennessee and Toronto I could calculate at least 340 gal each time I filled up the tank. Now, the reason I made this comparison is because I believed my Scion would let me go to East Stroudsburg (~110mi) and come back with only one tank. Well it didn't and I had to fill it up when I reached Fort Lee, NJ. I just put 10.5 gal after having put 10.28 last November 11. That is just one week for 225 mi driving from my house to Manhattan and a couple of times to Yonkers. I understand how MPG works, but you don't have to be a savvy to understand that by zeroing your odometer seeing that is has measured 225 mi when is time to put gas again this means your tank only gave you that amount for the 10.2 gallons you put the last time and in just 8 days. But I will make sure I do a couple of fueling to be able to provide you with more accurate information. One more thing, is it possible that when the filters were changed they were set to be filled up with a ratio higher than what's recommended?

Replying to: joseph07 (Nov 19, 2009 11:28 am) Regarding the Scion--one thing to keep in mind is that these little cars are geared (in the transaxle gearing) for acceleration, not for top speed. They are, in other words, not a "long-legged" car. This is why the 65mph + penalty kicks in. |

Replying to: joseph07 (Nov 19, 2009 11:28 am) Are the tires the stock 15" or are they upgraded to 16. 17, or 18"? Tire pressure at 35psi? Oversize rims and tires rob the Scion of mpg. I also get less MPG with the tire pressure set at the door sticker of 29psi. Oversize tires will make you lose mpg substantially as well as some oversize aftermarket exhausts. Some posters have complained that CAIs have robbed them of 8-10 mpg. My mpg drops from 32 to 28 when the stock 15" tires are rotated at the tire shop and they set the pressure back to 29psi. Have the plugs been changed with platinum tipped plugs as specified by Scion? I change the air filter every 10k miles and the oil is 5w-30 full synthetic. I have 101,000 on mine and it still gets 32-33 mpg and average about 330 miles per tank. I run it regularly from DC to NJ and back at speeds up to 80. I hope some of this helped.

Replying to: crazedcommuter (Nov 24, 2009 8:28 pm) Regarding the plugs, I have no idea whether these are platinum or any other material. I just know that when I bought it last month I expected the auto dealer to perform a 26 points inspection (whatever this means) and assumed they would change oil and plugs or anything that is considered essential for good performance after some months being parked. It currently has 37150 and as I said before, not in this opportunity, for instance, I put $30.02/10.5 gal on November 19 and combined it with a fuel system cleaner I got from AutoZone. That day I got 50 miles for 1 gal according to the gas meter, but the day after began to decrease progressively. As for today, it shows 198 mi for about 7.5 out of 10 gal consumed. Another thing I've noticed is that the gas meter fluctuates a lot, even when I turn the car on the same day. The other day saw it marked 5 gal (I assume each line represents one gal since it hast 10 in total) during the night, and when I turned on the next morning it had dropped to 4.5 gal or less. To make it easier, I already know the car has some kind of filtration, although the guys from Toyota service told me there is no gas leaking. It might be the tank cap or something like that, but I am thinking of taking it to another shop for another check up. Thank you for your comment. |
