Broke 50 MPG
Hi Everyone:
Well, it's been two months since I first broke the 50 MPG barrier. Just filled up my tank early this morning and the calculation came out to 51.542... I filled-up at the 7th Bar (1/4 Tank). I have been using the same hypermiling techniques that I've learned from this great Fuel Economy Forum! The only difference in driving this time rather than in May is that it involved a shorter trip (200mi), changing the tire pressure from 38 psi to 42 psi, and me using my A/C 1/2 the time of the trip. I have noticed with the vehicle that when the weather is hot the engine really likes the heat! Using the A/C more than usual for me seems to not have any effect on gas mileage? Has anyone experienced the same? I have increases my tire pressure. It's been in the upper 80's and low 90's in PA. The trip was during the height of the heat wave in the Northeast. I'm going to be taking another short trip at the end of this week and in the beginning of August. It would be nice to get two consecutive +50 MPG on this tank? Cheers! Gas Tank mile increments (non-ethanol gas used): 1st Bar drop (8/8) > 102 mi (102) 2nd Bar drop (7/8) > 86 mi (188) 3rd Bar drop (3/4) > 50 mi (238) 4th Bar drop (5/8) > 62 mi (300) 5th Bar drop (1/2) > 74 mi (374) 6th Bar drop (3/8) > 72 mi (446) 7th Bar drop (1/4) > 52 mi (498) 8th Bar drop (1/8) > 0 Tank total : 498 miles Fuel used: 9.662 gallons MPG: 51.542

Nice work my friend! That's awesome economy. I too have noticed the Yaris LOVES heat to the point it helps to offset the use of AC. I just got two of my best tanks ever (46.2 and 45.4 mpg-5dr LB auto) in humid 80-90 deg weather with almost constant AC use.

Congratulations. So when are you going to get that Ecometer or Scangauge to post some higher numbers ;)

I'm very pleased with the car's FE! It is exciting everytime I fill-up and wait for the pump to "click'... For once I don't mind going to the gas station! Cheers!

Funny thing you ask! I've been eyeing the Ecometer or Scanguage for some time now. Don't know which one to get? In August, I'm purchasing from Garm a rear sway bar. I found out he also sells the Ecometer for $59.95... that's a good price! I may just be placing an order now for two items... Cheers!

I couldn't agree more-fill ups are "events" for me as well.

I'm stuck hovering around 44 MPG. I need to start riding my bike to work again to eliminate all those 2-5 mile MPG-killing commutes. Then I will join the "50 Club" as well...
I'm surprised about the heat effect, since I always thought colder/denser air in the intake would give a bit more power? My car won't get any "heat assist" here, anyhow. |

Cold/dense air requires more fuel to combust, hence the increase in power.
However, more fuel is detrimental to FE. Hence why hot air will benefit the Yaris in your quest for FE. |

To take it to the limit, your arguement suggests that the thinner the air gets the higher the fuel efficiency will be. It obviously isn't that simple. |

No, it really is that simple, that's the basics behind the "CAI", or "Cold Air Intake".

Update: Broke 50 MPG... again
Hi Everyone:
Just the other day, I was able to reach consecutively 50+ MPG... this time 52.166 MPG. No different techniques then last month... and the same tire pressure. The only difference is I took two trips (200mi and 100mi) instead of one. It has been very hot and muggy! The Yaris loves the heat and highway trips... I'm using the A/C still about 1/2 the time of my driving. It seems that using the A/C has not had any affect on fuel consumption... Hopefully, I can make three consecutive 50+ MPG tanks? The cooler weather will be coming soon, the Yaris does not perform as well in FE for the PA Winter Season. Cheers! Gas Tank mile increments (non-ethanol gas used): 1st Bar drop (8/8) > 112 mi (112) 2nd Bar drop (7/8) > 85 mi (197) 3rd Bar drop (3/4) > 40 mi (237) 4th Bar drop (5/8) > 73 mi (310) 5th Bar drop (1/2) > 83 mi (393) 6th Bar drop (3/8) > 60 mi (453) 7th Bar drop (1/4) > 55 mi (508) 8th Bar drop (1/8) > 0 Tank total : 508 miles Fuel used: 9.738 gallons MPG: 52.166

What do you mean? Is this something you gather from Ecometer or SGII?
Cheers!

Sorry, I meant the temperatures. I'm trying to figure out what's the optimal temp for the Yaris to run in.
