The Eco Meter Explained

Perhaps i am misunderstanding, but wouldn't that be rather poor economy given those conditions? You followed your own restrictions regarding flat terrain and a warmed up vehicle?

 

I guess it was just disconcerting to see that even with a full battery and conservative speeds, you'd still ba getting half the mpg one would expect! Admittedly, I am still quite green when it comes to all this, so perhaps it's obvious!

 

First off thanks for the props man

Some thoughts on your thread.

The eco meter is very very dependent on speed to give you a given mpg. Meaning if your going at 40mph at just over the eco line you get something around 50 mpg. Going 42mph you'll be getting some where around 65mpg. this very odd occurrence is because of the CVT transmission. The thing you really want to look at is the RPMs the engine is running at. which will cost ya because the car does bot have a read out of it, you have to get a scangauge or ultragauge, or something of the like. Something els to think of is the road quality. In my drive to work the is a part a road that has been repaved this year and is very smooth. I pretty normally is a 10mpg bump in the instant mpg while on this part of the road.

The other this is that some of the time P&G is better than steady state driving. I hope you can get data of how best P&G can and when to be used. I think its going to be very hard to do.

 

If the C had a 5 gear auto trans I would say YES. Eco meter, speed, and battery level would give you a consistent data point. I have seen differences of over 1000 rpm with all of meters reading the same (speed Eco battery) which in turn gives you a pretty different number as far instant mpg. I say take a avg over a longer distance but its pretty hard to hold everything perfeactly.

I'm not trying to say your idea won't work it. Probably will he just fine and I'm looking too hard into it. I know this would not be the first time I have over thought something.

 

I took note this as I headed off to work of my intent mpg right as i started the car and got going. About 2 min after starting BOOM(my car C) at 41 mph with the Eco meter just over the Eco line, And a full battery (not really full 2 bars down but as full as it basically goes) my scangauge readout said I was getting 48mpg. Scangauge also said the front end coolant as 77F and my RPMs was around 1800ish.

Later in my in my drive I repeated. The differences were temp was 196F, RPGs at 1050ish and MPG at 90.

So to follow the rules . . . kinda sorry

41mph/just over eco bar(no EV)/5 bars/ temp 77/ RPM 1800 =ing 48mpg
41mph/just over eco bar(no EV)/5 bars/ temp 196/ RPM 1050 =ing 90mpg

 

Yes you did say at full temp. I was just kinda trying to reinforce why. Also something I did not point out befor but I have my grill blocked. Per grill blocking he max temp I saw was 188 after grill blocking it gets up to about 195-203. I did not watch it all that closely befor but the higher temp I THINK has helped my mpg.

It happened last week one morning when it was really cold and I had to park outside so the engine was like 34F. I will explore ways to try and snap a pic while not getting myself killed also but, less important to me, anyone else. It could be a while though because its not really all that cold yet and I do no intend to leve my precious BOOM outside just to prove it. That being said it will no dought happen soon or ( fingers crossed) later.

I don't know how you could of spotted me with out me seeing you as your color kinda sticks out lol. I also am surprised you could not catch me lol. Although your probably diving just the same as I am =-)

One other thing I'm going to point out and probably piss you off with is tire pressure. I keep mine at max side wall on the tire. Mine are 51psi. The car came with it at about 35psi I think I'f I remember correctly. I saw at lest a 7mpg bump after pumping up my tires.

51psi? Are those tires standard? I got a Prius C package 2 and I believe my standard tires say 42psi. I've pumped her up to 44psi.

 

I have a 4 so it might be different. I know I have different wheels than you for 100% sure just dont know about tires. My pal chicagoaficionado has a 2 though. Maybe he gave enlighten us.

 

Sorry for double quote. Im wondering if tire type and brand are different in different georgic reagents. i mean what come with the car. Jefreestyles Where are you from?

 

I believe the max on my stock tires reads 44psi, I inflated mine at 41psi and did get about 5-6mpg more on the freeway. Be careful not going over the max since your car will be bouncy and not have good control over the road.
