MPG Increase Projects - 04 Dodge Sprinter

This is going to be an ongoing post as I attempt to increase my MPG on my 2004 Dodge Sprinter (140 wheelbase, passenger, high roof). I have noticed that over the years I have owned it the MPGs have decreased and although that is to be expected with the added weight I would like to address what I can to increase it. So I have compiled a working list of what I have done and what I plan to do to it to help increase MPG.

*Numbers/Chart updated November 2019 (missing fill ups from June-November)

COMPLETED PROJECTS:

-Oil/Filter changes up to date (every 10000 miles - Mobile 1 Synthetic and Mahle Filter)

-Transmission Fluid and Filter Change

-Air Filter replacement regularly (Air Filter w/Pre-Filter)

-Fuel Filter/Water Separator Replacement (Mann Filter)

-Monitoring via ScanGaugeII

-EGR Valve Cleaning (Mar 2019)

-Crankshaft Position Sensor Change (Mar 2019)

-Rear Differential Fluid Change (Mar 2019)

-Less Restrictive Muffler/Cat Install (Summer 2020)

POTENTIAL FUTURE PROJECTS:

-Wheel Bearing Replacement

IMPORTANT NOTE: At the time I installed larger tires the speedometer changed it speed and it may have affected miles driver per tank, which is where my MPG calculations come from. Something to keep in mind.
