Does your car ever have "slow" days? - Page 3 - Toyota Yaris Forums

Glad to know me and my Friends (Yaris owners) ain't the only ones who noticed this. Since I don't know why it does it I like to think my Yaris is a real Biatch!!!

When the A/C is one mine is a slug!!!! With it off its pretty peppy once its warmed up.

My car drives best at 4:45 am on my way to work. Perfect temp for the engine!

YAR1S · 09-24-2009, 08:50 PM

Could it be that on the so called "sluggish" days.... your gas tank is full or somewhat full... and on the "quicker" days your gas tank is closer to a quater of a tank or even near empty??? This crossed my mind today mostly cause my yaris seemed to be a lot more zippy-er and it was below 1/4 tank.

5.93 to 6.42 lbs, depending on temperature, type and blend (e.g. with methanol, water, benzene etc).

The question was "what does gas weigh a gallon?"

Bob Dog · 09-24-2009, 11:43 PM

not but 50 or 60 lbs diff....m but I have noticed it seems that way to me sometimes

YAR1S · 09-27-2009, 06:39 PM

ah, 60 ponds lighter could make the yaris seem quicker, IMO.

ozmdd · 09-27-2009, 11:06 PM

I suspect that the weight of gas and A/C use are definite factors here. Also, the Yaris seems fairly sensitive to humidity and air temp. Since I've installed the CAI, I notice significantly more pep, even when the air is hot. When its really humid, nothign really helps with the loss of "oomph."
I've been tracking my intake air temp with the Scangauge for a while, both before and after the CAI, and the correlation between the change in air temp is pretty apparent to me.

found this, but don't quote me on it!

Water: 998 kg/m3

Gasoline: 720 kg/m3

Diesel: 830 kg/m3

i wonder if lower octane fuel weighs less, haha
