What kind of gas mileage are you able to squeeze out of your thirsty 4.7?
For years I’ve been getting such horrible gas mileage that recently I started doing some research on engine oils and fuel additives and proactively started trying everything humanly possible to get any sort of improvement in my fuel economy.
To my surprise, I was actually able to raise my gas mileage quite significantly. With just a few engine and exhaust modifications, a tune, a little of this and that in the gas tank (wink wink) a few extra pounds of air in the tires and a switch over to 0w20 oil, and 16 new spark plugs later, and I’m now seeing numbers I never thought I’d ever get with this truck.
Before the changes I was seeing maybe 8-12mpg... on a good day. Now? 21-30mpg. Seems to get better mileage just putting around town.
I made a little video. Check it out.
