Id like to pick every ones brain for a quick moment if that would be okay. The mods i am almost sure work that i plan on doing are the electric fans on my 2001 F150 4.6, the bed cover, 50 psi tires and new oxygen sensors but there are a few i want to ask about.
1. I read all the time about how air intakes are suppose to raise your gas mileage, is this true or not.
Cold air intakes seemed to help my mileage slightly when I was still driving like hot rodder. If you use less right pedal, warm air intake will usually yeild better mpg.
2. I'm not a huge believer in fuel additives, but is there something out their i have been missing that really does work?
Fuel addatives are mostly for cleaning. If everything is carbon free, you won't see real differences.
3. Would lowering the truck 4 inches really yield a noticeable increase? Enough of one to justify spending 400 on getting it done.
$400 is 100 galons of gas, what's the payback on that? Try a chin spoiler of garden edging--closer to $4.00. It will give you almost the same effect.
4. Would a 5-10 degree hotter thermostat help lean the mixtures out some.
Perhaps it will help a little. A warm air induction system will help you burn less O2, thus less fuel.
5. Does lowering the tailgate really work?
Lowering the tailgate will hurt your MPG. A tonneau cover will help. A custom aero boat tail bed cover will help more...
Sorry for all the questions, i have never had access to a community such as this one before and i think you all would be the best to ask.
