Well I rotated my tires this past weekend and have seen the mileage drop back down to 18mpg. It was the tire wear giving me the 2mpg increase.Greybrick wrote:Your gas mileage will get better as your tires wear down, less tread block wiggle/friction generated, so you should see a steady improvement from that.Ride2Live wrote:Just a note: I just noticed that my 06PF mileage increased from an average of 17-18mpg to 19-21mpg somewhere around 20k.
Same driving habits, same octane fuel..., I started using K&N filters and Mobil1 back at 9500mi so don't really think it was influencing the increase?
I suppose the drive train is still in it's brake-in perhaps? dunno... but with $55-60 fill-ups I'll take the extra miles!
This 07 S-model with about 5K miles is getting 25mpg at 65mph highway and around 21mpg city if my wife doesn't drive, lol, her city mpg is 17-18. About the only change that I've done is pumped the stock tires to 44 psi sidewall pressure, and put in Castrol Syntec 5w-30 at the first oil change. The Castrol gave 1- 2mpgs improvement over whatever the factory fill was as soon as it was in.
A good place to check topics on improving mileage is at cleanmpg, one of the recent threads shows Castrol Syntec 5w-30 to have the lowest 40/100C/HTHS viscosities of any of the major oils available. Some friends use Scanguage in various types of vehicles to get an instantaneous readout of mpg for any given driving situation and see immediate mpg improvements results as well.
Winter-blend fuel can make a difference this time of year on gas mileage, so that might be something to consider. A CAI isn't going to improve your gas mileage and, technically, the factory air cleaner is a "cold air intake" system. If plugs are worn, they could affect gas mileage. The original type, NGK plugs are recommended for replacement at 105,000 mile intervals. One of the biggest factors on gas mileage is one own's right foot! The electronic throttle is fairly sensitive. I get my best gas mileage when I use cruise control as much as possible and keeping a light, steady foot when I can't. At that, I still get about 17 MPG combined, on average. Trips where I do a lot of highway driving can see 21 MPG. Short stop-and-go trips on these vehicles kill the gas mileage.Reliotter wrote:According to the dashboard calculator I'm 16mpg...wtf. This is even on roadtrips. Does that fact it's 4wd make a diff.? I'v reset the computer and still the same. Maybe plugs, CAI???

With the 4wd, you are carrying quite a bit extra weight so gas mileage is going to take a slight dip from a 2wd version, new or not. I have a 2011 4x4 and get about 15 in the city. On the highway I get about 18ish. I would attribute this to the Pathy having the areodynamics of a brickElishas wrote:same questionReliotter wrote:According to the dashboard calculator I'm 16mpg...wtf. This is even on roadtrips.
