Not another MPG thread...
Okay so every thread (the million of them) about mpgs always asks what's the best mod for mpg. Most answers come back as maintenance and fluid checks right? Well what kind of maintenance and what fluids do I need to look at/change/synthetic?

ok i was gonna put read the sticky.. which you should anyway if u havent
Air Filter
Fuel Filter
Sythetic Oil
Clean MAF
Clean Throttle body.. i donno but might help
not really maintenance but..

I did the Gott's mod but my mpgs went from 15.5 to 13.5...removed it and went back to 15.5 so that's out. Cleaned the MAF and TB and changed the oil last weekend actually air filter is an airaid.
So no fluids like tranny or diffs would help out?

I thought it was just my imagination but since I did the Gotts my MPG may have gone done a bit. I might reverse it and see what happens. Has this happened to anyone else?

The gotts mod means more efficiency which theoretically is better mpg. However if you're heavy footed, you will definately lose mpg with this mod. Also, if you didn't do a reset by disconnecting the battery, it will run inefficiently for a bit until it eventually relearns the new mix. Give it a chance and drive it like a grandma, and you will see better mpg from it- but it takes a lot of self control as it does open up some fuel sucking power as you're able to mix more fuel:more air.
I'm shocked no one mentioned the upstream o2 sensors. That was my biggest mpg improvement, personally.

I think cleaning them is a waste of time, but some believe in it. As far as I'm concerned, unless you have some way to remove years/miles of superheated carbon buildup, electronics/CRC cleaner isn't going to touch it.
I mean, if you're going through the trouble of taking off a $50 'maintenance' part, might as well replace it.
You can get a pair of upstream Motorcraft O2's for about $110 from Rockauto.
You need an oxygen sensor socket that accomidates the wire-design, and some penetrating oil doesn't hurt. I would throw a tiny bit of antisieze on the new sensor thread, being careful not to affect the sensor.
Takes about 20 minutes. Also, unless you're getting codes, just change the upstreams--- personally- I left the downstreams in and had them disabled in the custom tune.
If your area is strict on emissions, leave them on.
*edit; You may be tempted to buy Bosch sensors as they are more expensive and presumed better; save your money--- the motorcrafts are better performing and last longer. (imo)
