About FuelMaster

A US company helping drivers spend less time thinking about the pump.

FuelMaster™ is sold by North Star Advertising LLC, a US consumer-products company based in Las Vegas, Nevada. We focus on one thing: simple, affordable car accessories that ordinary drivers can use without tools, apps, or a trip to the mechanic.

Gas prices are one of the biggest line items in an American household budget, and most of the advice out there — buy a newer car, drive less — isn't realistic for most people. FuelMaster is our answer: a plug-in device you can try in your own car, measure against your own fill-ups, and return easily if it doesn't earn its keep.

How we operate

• US warehouse: every order ships from our warehouse in the United States within 24–48 business hours, with free tracked shipping.
• Real support: a human answers support@getfuelmaster.com within 24 hours, 7 days a week, and picks up (253) 296-2316 on weekdays.
• Honest expectations: we don't promise a specific savings number — results depend on your vehicle. We'd rather you test it yourself under our 180-day money-back guarantee.
• One-time purchases only: no subscriptions, no memberships, no recurring charges.
