Okay, I'm finally getting ready to cross-over to Range Rover family, so I have a Mazda Tribute and it's getting HORRID MPG, I believe I'm averaging about 18 mpg, but I only have a 16.5 gallon tank, so I'm getting 240 miles to the tank, so Im sick of the car at any rate and at first I was scared to get such an expensive high maintenance vehicle, but what the hay, lol. so, I'm getting the classic 02 HSE, what can I expect on the mpg tip. Also, what gadgets help increase gas mileage in the RR if there's any.

*NOTE* I drive about 70%-80% highway miles a week.

 

With mostly highway driving you could probably expect to average around 17 - 18 mpg, as a rule. Best thing I'm aware of to keep your mpg up is to stay on top of your routine maintenance, use good synthetic lubricants, keep tires up to recommended pressure and try to avoid aggressive driving. I'm not aware of any "snake-oils" or "black boxes" for these vehicles that will magically increase your mieage.
