Better driving habits, maybe upgrade to 24.5 tires if you're running 22.5s.
No!
Helps improve fuel mileage.
An aerodynamic cab one, like a Freightliner Cascadia, International ProStar or Volvo VN680.
yes, but they require that you only run Premium fuel. The savings on mileage is offset by the extra cost of the fuel, and its not worth it.
The 2003 Cavalier has an expected mileage of 22 mpg in the city. Highway mileage is an expected 30 mpg.
If you are referring to E85, from my experience using E85 actually lowers the fuel economy.
Freightliner doesn't make motor homes - they supply the chassis for them through Freightliner Custom Chassis, then they ship them to whichever customers... Winnebago, Fleetwood, and Allegro are among the purchasers of Freightliner chassis for motorhomes.As far as fuel mileage goes, you can expect between four and eight MPG... a lot of it really depends on your driving habits. These tend to use lower displacement engines than a semi truck, and are typically geared lower, so you'll be turning higher RPMs at speed. Driving 55 MPH and driving 75 MPH will produce two very different fuel mileage results.
Keeping up with scheduled maintenance, better driving habits... a lot's been done since ACERT went into effect in the early 2000s which has impaired fuel mileage... EGRs decreased fuel mileage, SCR/DPF/DEF decreases fuel mileage, 2007 introduced Ultra Low Sulphur Diesel - which is a less efficient fuel than the previous low sulphur diese - all in the name of emissions. Turbocharging remains the best option to improve diesel efficiency.
Install a hydrogen fuel cell. Google fuel cell llc. I noticed their first cell produce is for the N14
A Chevy Avalanche uses standard 87 octane fuel. Higher grade fuel will not result in improve mileage or performance.
no, they just mean that the engine has a supply of hydrogen to run on rather than any other fuel
High performance exhausts can have a small, yet statistically insignificant, impact on fuel efficiency. They tend to be installed for a differenct exhaust sound or improved power, not improved fuel mileage.
