Dodge Ram 1500 QC / 5.9L Advice
Got 13.5 MPG (based on 4.5L gallon) with 60% HWY and 40% City on the first tank.
Now am averaging just 8.5MPG 100% City on the second tank so far.
I am considering the following steps to improve mileage:
1) Add a K&N Air Filter in about a month when available. (Has anyone with this engine had good results with a K&N?)
2) A Tornado Fuel Saver - but not yet available.
3) A cover for the box.
4) Switch to M1 synthetic. How many miles should I wait until I make the switch? I have seen anywhere from 5K to 15K miles.
5) Just wait for it to "break-in".
What should I expect from this engine and which steps would yield the most improvement? From what I have read - the 5.9l is not much worse on fuel than the 4.7L.
Luckily, I really enjoy driving it, it looks really sharp, and I am pretty sure I will be able to tow anything.
Any ideas or feedback would be much appreciated.
