I only got 200 miles out of my last tank of fuel...mixed driving highway/city. A/C on all the time...I wonder whats up? The tank before was 320ish?

 

maybe you step on the gas way too hard?

 

Sounds like fuzzy math or you didn't get the fuel you paid for on the last tank.

 

I don't know what I did. I haven't been driving any different. Maybe I didn't get the tank completely full. Heck, I don't know. As far as fuzzy math...I haven't done any math yet...just looked at the ODO and the fuel gauge. No math involved there.

 

did the needle on the fuel gauge reached "E"? did the light came on yet?

 

Gas quality is a pretty big deal...never go to a no-name gas joint...always buy brand-name gas...I recommend high octane in these cars as well. 10.5:1 compression warrants it.

 

10.5:1 is right, but the computer has the timing preadjusted to handle it.

 

The manual suggests the 87 Oct gas, not premium.
These are budget boxes, not sports cars.

 

I used 93 octane to see if there was a significant difference one time, and found that it was not near worth the .10 plus cents a gallon. Last fill-up for me was 329 mi. using the tripometer and 9.3 gal. 87 octane, that is 35+ mpg. I have 11700 mi. on my box and my average for all miles is 33+, If you want the best milage out of these things you need to drive with a steady foot, no up and down on the pedal going down the interstate, give it the throttle that is needed not flat out all the time. I drive half highway and half rural roads here in Pa. with a 6% grade mountain everyday going to and from work and found that somewhat higher speeds on the intestate 70+mph got me better milage. Key thing is a steady foot!!!

 

Yep...and the manual goes on to say "research 91", and that the car MAY ping, but it's 'normal'.

Why do all the bookworms here conveniently leave that part out when citing what the all-knowing MANUAL says?


I refuse to allow the potential ping, much less the resulting retarded timing compliments of the knock sensor.

 

I totally agree with this as it relates to gas mileage.


However, I stand by my high octane.

 

xActly, whats the price of hi-test up there. Regular here is $2.55.

 

all gas makers must abide to strict federal guidelines when it comes to making the gas, i reckon the difference is when they store it. I say this because when the gas is in the large tank at the station it builds up condensation, and water gets contaminated in the gas.Water and gasoline do not mix. While there is water in any gasoline storage tank, it floats on top of the gasoline. This is checked frequently by 'sticking' the storage tanks with sticks coated with a water-reactive substance, to show where the water level is, and to make sure it is not at the bottom of the tank, where the outflow pipe is. Different gasoline grades come from the degree to which the gasoline is refined; more refining gives higher octane

but, Some gas stations do add gasoline-soluble additives to gasoline, such as cleaners. This is what makes the difference in performance, not the water content of the gasoline.

yup

 

I get over 300 miles on 1 tank. I'm not hard on my car but I do use the ac alot in the summer.

 

lol xACTLY. You truly know that you DON'T need high octane in these engines? ok, wow 10.5:1 compression....other cars with the compression ratio ie. the new Civic, need REGULAR.

10.5:1 is the perfect compression ratio. High enough to get more performance out of the engine, and JUST low enough to run it on 87 octane. You are WRONG.

 

hmmm...I thought water sinks to the bottom of the tank? when you use the measuring stick(glorified xtra long ruler) to measure the amount of gas and water in the tank, you put some type of paste on the bottom few inches of the stick and if there is water present, it changes color up to wherever the level of water is. At least that's my experience from owning a convenience store.

 

That is correct Water is heavier than Gas,And with all the new EPA/DEP standards and monitoring equipment when there is too much water in the tank they start getting alarms. And it is all reported to the EPA/DEPon the average of once a week.
At least is that way here on the east coast.

I didn't think this thread would go this far and I didn't want to start another "bad gas mileage" thread. All I was saying was that all of a sudden, I got under 200 miles ut of my last tank and didn't know what was up. I thought maybe some of you may be able to point me in the right direction as to something going wrong or failing. Maybe it was just bad gas?

 

There's either (a) something seriously wrong (like your parking brake was engaged the whole time, your tires are almost flat, or you're stuck in third) or (b) you didn't really fill the tank. If you didn't notice any performance issues, I vote for (b).

Forget it. Keep being a moron. I really don't give a flying fawk.
