Spark plugs and or wires may need changing. Air filter dirty. Tires not inflated to the correct PSI. Or it may be how you drive. Drive fast with jackrabbit starts and stops and you will get poor mileage. Plus, you are driving an van and none of them get great mileage.
bad gas mileage
The Dodge Caravan and Chrysler Town and Country have some fantastic gas mileage for 2012. It seems like gas mileage is getting better and better each year.
The new Sienna and the Caravan both have high gas mileage. The Town & Country is another great minivan, it is the vehicle I currently own and love.
I don't know, but if you can figure it out, sell the secret.
Bad gas mileage can sometimes be attributed to a vehicle in need of a tune-up. Have your car serviced and see if that improves the gas mileage.

Yes it can reduce gas mileage. There are usually two kinds of faults with FPR that reduce gas mileage. 1. Excessive fuel pressure. 2. Fuel leaking through vacum. Both these faults result in bad gas mileage.
