GadgetmanSweden hello, This vehicle is a 1998 Ford Expedition full time 4wd.
It's a step bigger than a Ford Explorer.
It has a 5,4 Triton v-8 engine.
It has not been uncommon for the expedition or the Explorers to double in mileage.
The lady is so pleased that I have earned her maintenance and repairs for the life of the vehicle.
The groove indeed makes a great bit of difference.
This is the only modification I have done so far for her.
Go back on the posts to Ford Expedition gains mileage on 3rd page of forums to see temperaure changes on this vehicle. I believe it will make you smile!!!!
It's great to hear from you sir. Gadgetmannebraska Aron Cheek
