Bad fuel mileage

10

Asked by JocksFix Apr 15, 2019 at 10:55 AM about the 2006 Dodge RAM 1500 SLT Quad Cab 4WD

Question type: Maintenance & Repair

I have 2006 Dodge Ram 4.7 L with 300,000+ miles.
Maintenance has been kept on it but the fuel
consumption is ridiculous. I filled up yesterday and
today it’s already at 1/4 of a tank with 100 miles
put on it. Any advice on how to improve fuel
consumption???

Just a partial list of things to check; timing, injector pulse (with a noid light), all the tune up stuff (plugs, coils, wires, cap/rotor), leak down test and/or compression test to look for excessive blow by, wear on torque converter or on clutch, dragging brakes, fuel pressure/filter and fuel regulator. Do you have a check engine light on? Transmission issues may not set codes, and things like late shifting or loss of O/D can really blow your gas mileage.

Any parts store can read it free of charge. The OBD code will be your biggest clue as to what's wrong with it.
