1997 buick century 84500 miles regular maintanance, oil change every 3000 miles. son taking trip in it. never had radiator flushed, plugs changed, transmission fluid changed, should i have concerns on...


Yes, this is very important maintenance procedures. Transmission should be serviced (filter, oil, and oil pan gasket replaced) @ 60K miles, plugs at 100K miles (I'd replace them early for better gas mileage), and radiator flushed @ 60K miles. Hopefully this helps!!

Fuel Filter for Sport Trac


If the car is running good no engine problems or poor gas mileage I wouldn't worry about it. This is done as preventive maintenance. Every tune-up parts have replacement recommended periods. Ignition components, all filters and lubricants should all be replaced the most every six moths depending on how much you drive. Its all common sense if you check your oil and its black its time to change it. If your brakes are screeching same thing and if it been six month probably well over 15,000 miles since you replaced the fuel filter it'll be a good idea to change it.

Lost gas mileage please


Lost gas mileage. I would have to assume that you are not getting the require mile per gallon. For example If the car book say 32 miles per gallon. You are getting about 20 to 25 miles per gallon.
If you want to improve the your gas mileage then you have to do the required maintenance
Oil change every 3000 mile
tune up as required
Air filter
If the wiring spark plug wire is old and crack then it need to be replace.
If you park out side and the batteries is about 5 years old have it check
If you buy the car new, you will have a car book follow the maintenance routine.
If you have done all the maintenance and the gas mileage is low than recommended then take it to a shop to figure out if some thing is wrong or not preforming as it should.
I do hope this help you.

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.

Poor gas mileage on my jeep liberty


Did this happen overnight or was it a gradual loss? Did you do any kind of repair before you lost the gas mialage? Is there a check engine light on or did it come on and go off? Did anything weird happen before the jeep got bad gas mileage? It's hard to diagnose a problem like this without actually touching the car.
Any other info might help me steer you in the right direction.

Jeep liberty gas mileage


when was the last time you put in fuel injector cleaner? I put in Lucas Oil Injector cleaner every other or every oil change.

There are alot of factors affecting your gas mileage. Tire wear, tire pressure, wheel alignment, air filter, fuel filter, spark plugs, oxygen sensors, just to name a few. So to say what you need is just shooting in the dark without more information. I would probably start with your oxygen sensors, and then perform a tuneup. If your vehicle pulls to one side or the other when driving on the highway you need to stop into the shop for a wheel alignment.

Gas consumption


My Answer:

Poor gas mileage can be a result of many many things.

First of all you need to find out what is the factory normal gas mileage for your model year Jeep SUV. It should have said on your window sticker if you bought it brand new. If you are a 2nd or 3rd owner then a Jeep dealer would have info. Google search will tell you as well, and only takes a couple minutes to find.

I did a quick Google search and for a 2003 Jeep Grand Cherokee with a (4.7L V8 engine) the average mileage is roughly 14 mpg.

Not sure what engine you have as to options, etc?

How you drive will greatly change that number up or down depending on a number of driving and driver variables.

A few being -

Driving habits?

Tire pressures?

Engine tuned up?

Lube & oil/filter changes (every 5,000-7,500 miles? Air filter changes (every 10,000-15,000 miles)? Read your auto manual for exact recommended intervals.

How many people in the SUV on average?

Are you towing anything?

Type gas you are burning - BRAND? (See injectors below)

Area you are driving in (hills and valleys verses flat out,
etc)

Jeeps in general don't have a good track record for great mileage, and rough engine idling is always a clue that your fuel injectors are dirty. Typical on all Jeeps with port fuel injection systems! On Jeeps with dirty fuel injectors your mileage will go way down accordingly. If your not putting at least a 12 oz bottle of say Walmart brand Super Tech Fuel Injector Cleaner (~ $1 each) in your gas tank religiously every logged 1000 miles, or every 2 tank fill ups, then you are just inviting dirty fuel injectors and POOR fuel economy!

My 1993 Ford XPLR with a 4L V-6 engine (and ~ 160,000 flawless driven miles) gets roughly 22 miles per gallon on the highway with cruise control on, and about 17 around town on average. I religiously put a 12 oz bottle of the above injector cleaner in my gas tank every 1000 miles!! Of course I do all my own tune-ups, general repairs, and suspension maintenance (shocks, O2 sensors, trans oil changes, lube & oil/filter changes, code reading and clearing, etc) myself and it shows! I don't trust repair shops except for say Tires and Balancing at SEARS.

Hope that helps ease your mind about gas mileage as it relates to your Jeep there.
