mpg

My 04 dodge caravan has been burning gas like crazy lately. I keep everything up to date oil air filter etc... I was thinking of some fuel system cleaner... It only has 20k.. Any ideas??

How fast. We have a 2003 with a 3.3L flex fuel.
On the highway w/ 94 oct we are getting no better then 21.9 and no less on highway then 21.1.
In the city 18 i think.
What oct of fuel are you using? What engine do you have? Need more info to help you.

Your van is still under warranty. Take it back to the dealer and let them fix it.

What kind of mileage are we talking about? How much oil are you putting in it after oil change? On my 2003, it said 5 quarts, but that is 1/2 qt too much. It actually only takes 4.5 qts and only use 5W-30 or lighter. I was getting 15 mpg after my first oil change and i took it to the dealer and they could not find anything wrong with it. I then checked my oil and it looked overfilled and i drained it and added 4.5 and my mileage went back up.

I was refering to the Full Synthetic 0W-30!

2001 caravan 3.3. 17.5 normal driving. Installed a tornado and went up to 22 mpg! I also tried the tornado on my ford explorer and I actually lost 2 mpg. Go figure.

Im not a big fan of full synthetic because it messed up my engine in my last car. But do what you want.

Its a grand caravan, so 3.3! I'm going to add some fuel system cleaner before i go on my trip. I will be able to check the highway mpg this way. I'll let ya know the exact mpg when i come back..

Thanks....
