Get Better Gas Mileage On your Ford!

Wow!
I have a 2001 Expedition EB and owned it since it was new. When it was new it got about 17 mpg on the hwy and 15 in the city. Not bad, gas was about $1 -$1.25 per gallon back then. As it has gotten older it was getting about one mile less give or take. It now has 127,500 on the meter and is still in great shape for I take real good care of it. As of late my fuel consumption has gotten real bad.
I took a look at my maintenance records and found that I had done all I could to get better gas mileage except my PCV. I did not have a time for the change in my records but I new it was changed with in about a two year span. A PCV life span it about 25,000 miles and I put that many miles on the truck in two years.
So I locate the PCV from OReilley's auto parts for $1.83 out the door. Replace the part and filled up at Sam's set the trip counter to zero.
Wow! What a difference at the gas pedal. Barely touch it and it goes. Also better start up and warms up quicker. I thought that was nice and wondered if it was going to get any better gas mileage. The fuel needle had not moved after about 21 miles shopping around town. I went back to Sam's and was barely able to pumped in, get this, 1.031 gallons! That's right! I got 20.36 on one gallon. I will be changing out this low cost part when I change out my air filter. I do this every 10,000 miles. I encourage you to do the same for your vehicle. Your pocket book will love it!
Amazing!!!!!

Sounds like you have an underlying issue causing excessive oil to get caught in your PCV valve and clog it up. How does your oil look and how often you you change it? What kind do you use?

A just changed mine for the first time after 80,000 miles last year. The old one was still just as functional and clean on the inside as the new one. And I don't replace my air filter until it's visually dirty. So far, 20,000 miles on both and both are clean as a whistle. Don't waste your money if not necessary.

I change my oil every 3k. Motorcraft 5w 20 and looks great! The old PVC was not clogged up. It still had some movement and a little oily. PVC's should move freely. As stated above you should change out your PCV every 25,000 miles. Mine was due. As for my air cleaner it gets dusty out here so every 10,000 miles is not wasted money for me. The mileage and performance shows what a new PCV does.
