21 MPG whats wrong

[rningonfumes]

Okay, drive in D for a tank and report back. I suspect it'll only improve a bit. And drive like normal no adding miles. We want this to be somewhat scientific ie testing only one variable at a time--- the D vs 3rd gear driving.

To comment on my " I suspect it'll only improve a bit". ---- This is because if your car is still "warming up"....it won't shift higer than 3rd gear. *I need someone to back me up on this because I have a manual and am relying on memory from previous member's threads/posts.

And driving no further than three miles? AND letting it warm up for three minutes before driving? Yeah, that will do it. Mystery solved.

I have a Scangauge II. I let my brother-in-law borrow my Yaris for a week. He complained that he was only getting about 25 mph. When he returned, I had him take me around the block. He put the automatic right into D-3. I pointed out to him that was setting the trans into third not higher gear. He was ticked off that the shift mech was so poorly labeled.

I was guessing you were not in third.

Not uncommon, I am currently helping my niece practice for her driving test next month and she often "slams" it into 3rd like Frank Bullit before we get going.

Short trips, cold weather, + the cold engine shifting restriction. Well you were always in 3rd and never going to get out of it.

Hopefully that's it. Keep us posted on your mileage.

cheers.

*Usually takes me about a mile or two, before my automatic is allowed to up shift in the winter, shorter in the summer.

Who has a scanguage? is it just plug and play? where can i get one

[P205]

Great thanks for the reply, I will now being driving in D " not drrrrrrrrr"
I drive a manual truck all my life, then i have to learn to drive automatic lol

Ill post results soon

[NEexpat]

You can buy a Scangauge II online.

It plugs into the OBD port.

I personally use an UltraGauge. I prefer it aesthetically, but mostly because I'm a cheap bas.....well anyway.

Update. so I have been driveing in D now. its looking like no change, when my first bar from my gadge gose away i have gone 45 to 47 miles witch is what i have been getting when i was driveing in 3

any ideas?

[rningonfumes]

Read my posts again about the cold.

[P205]

yea. humm . i was getting the same mpg in the summer. my cold temp gose out before i leave my street

[NEexpat]

Forget the bars. I've had my first bar drop as low as 61 and as high as 92. Go by the pump and the miles.

Suggest if you have the time, money and inclination. Fill your tank, set ODO A to 0.0 and go for a long sustained drive at speed, 65 etc. And by sustained I mean several hours, at least 3. Then go top of the tank and see how it went. If you have cruise control lock it in. See if you get in the mid to upper 30's.

I can't believe you're not going to see improvement by just getting out of third. I think the short distances and the temp affect more than anything. I wouldn't be surprised if you got into the low to mid 30's from your city driving.

cheers.

I feel like im doing everything i can possible do right but still
all summer iv been getting 21 mpg, winters here and im lettting it warm up for about 2 mins still 21mpg

I think your mpg calculations are off as if there was a problem that gave you that much of a MPG decrease from normal a check engine light would surely be on.
My 08 sedan is mostly driven around town and i get around 500kms/300miles per tank which i think is in the normal range.

PS isnt it an 11.1 gal tank?

[P205]

humm who drives in cold weather here

[yarisugi]

You're right Jambo – 11.1gal tank. That translates to 19mpg – SUV territory. lol.

Other options:
1) Commute is two miles - sell your car, ride a bike.
2) Remove your interior, leave the driver's seat.
3) Replace air in tires with helium. It really works!
4) Get rid of the decomposing corpses in your trunk.
5) Lose the girl, save two miles.
6) Lose weight.

All jokes aside, at least you're driving in "D" now.

[P205]

lol well if i was any lighter float to work. but anyways i guess im just screwd

[NEexpat]

Seriously, go for a long drive and see what your mileage is.

This will give you some indication if it just your particular commute circumstances or if there is truly something wrong with your car.

And if you mean screwed by owning one of the most reliable and dependable cars on the road today, then we are all screwed.
