My truck is a 5.0 V8 13 F150. Try this it works.

I took one of the 4 tires and rims off. Since then over a week ago the truck has used no gas at all.

Far cheaper than buying an all electric truck, and no electric costs.

Did you also know Ky governor is legalizing pot? Can’t remember his name. But that too will save gas cause people drive faster on the roads than they do on the sidewalks. Brilliant!
