Poor gas milage

75000 miles, Gas milage seems to vary. For several months my mileage was 19-21 mpg. This past month or so the milage has been from 16-18 mpg. My driving style as not varied that greatly.

    If you have no check engine lite on the system is operating within specs, temp changes and tire pressure also affect fuel MPG. U must keep in mind the engine is starting to wear at 86,000 miles.

Not sure where you live but if the gas you get has a higher amount of ethanol in it you will get worse gas milage.But there are many reasons that effect gas millage.

Poor gas milage?


Thinking you are getting poor gas milage,Your engine is running smooth,no misses,Engine runs smooth while accelerating up a hill, Still poor gas milage, Check your tire pressure. I have a 1999 Chevy Blazer 4x4, 4.3 Ltr. Auto, loaded. I have just over 154000 miles on it,I change my fluids every 5000 miles. Summer driving milage got real bad. I drive a Blazer hard. I tow a 16ft trailor usally loaded to the top with wood. Tires get hot in the summer, while in the winter, they stay mostly cool. Always check your air pressure.Most vehicals are equipted with radials now days, So if you think a tire looks low, check it, Usally they low. Usally in the winter months, nobody checks tire pressure. It really does make a difference. I went from 17.2 MPG to 19.5 MPG, while pulling the same trailor loaded with wood. I cut my own wood then stack it in my trailor to sell. I have Good Year Wranglers size: P235/75R/15 I just replace these with new ones. The old ones are going on my trailor. Counted milage on tires are 65000 Miles. Tires were rated at 40000 miles, Under normal use.

Poor gas milage in winter only 150 miles to a tank of gas


Air is colder or more dense needs more fuel to make mixture correct. Is the exhaust tight. I know v6 had donut seal problems. would **** air in and 3rd o2 sensor would read lean and ecm adds more fuel. Just a thought

Tune Time.
1)new spark plugs properly gapped.
2)new air filter (check every 35000 miles)
3)new fuel filter (every 35000 miles)
4)1 bottle of STP fuel treatment (red bottle) 4x a year.
5) oil and filter change (castrol or another good quality oil every 3-4000 miles.
6)proper air pressure in tires (check every 2 months
7) service transmission every 40000 miles or less.

New oil and filter
8) new plug wires every 80000 miles.

2007 kia rondo seems to use alot of gas


I have the same issue of low gas mileage. My 2008 Kia Rondo with V6 (2.7Lt) gets 20-21 mpg in average. Even for highway mileage, it is around 21-22mpg. Very poor gas mileage. Disappointed. I hope it would improve in the future.

Poor gas mileage on my jeep liberty


change your spark plugs if they haven't been changed in awhile. check your tires for the propper psi there should be a sticker on the inside of your drivers door that will tell you recomended air pressures go by this not the recomendations on the tires. also where are you getting you gas does it contain ethanol sometimes this can burn faster.
