Hi. I should be getting a 2007 Nissan Frontier soon. I want the Crew Cab, V6, 6 speed. Now, I want to get good gas mileage, and have a good amount of power (I won’t be drag racing or anything, but I do want some good acceleration. Plus I will soon be volunteering for the local fire department.) Without voiding my warranty. Right now I’m consider a supercharger, cold air intake, a speed chip, and re-program my computer. How much would this improve my fuel economy, and would any of it void my warranty?

You’ll use less gas if you keep your vehicle tuned up and running like it should
Continuous up and down acceleration and braking lowers your gas mileage. Use your cruise control on the highway to help maintain a constant speed and take it slow and easy on starts and stops. Slow down a little in general if you can, because the truck uses more gas when you drive at higher speeds
Use a good brand of gas, one with detergent additives that keep the system clean, but don’t buy more expensive premium if the automaker recommends regular
If you’re stopped in traffic, turn the vehicle off, don’t sit there and idle for ten minutes.
Air conditioning makes the truck use more gas, so turn it off when you can and try the vents instead
Combine Trips
foll0w your cars maintenance schedule
you can install a better intake manifold
then use premium gas
make sure your tire pressure are not too low
dont carry unnecessary items in your trunk
synthetic oil after the break-in period, check out Amsoil 0W-30:
There’s no way to accelerate hard and still get good mileage. You can minimize the damage of accelerating by pumping the tires to at or slightly above the listed maximum on the sidewall and minimizing the amount of time you spend idling (don’t do drivethroughs). Upshift early whenever you don’t need to burn rubber.
