Re: Any suggestions on increasing MPG?
There's no easy way to increase mileage on a 2.5 ton SUV. I know first hand. I've tried, but since I use it mostly for towing I keep it for that alone and drive my car when towing the trailer isn't required.
First off, be sure to check your tire pressure, bring it up 1-2psi below the maximum. This gives you some leeway when driving on the highway, even in the winter, tires will warm up and you'll be at, or just over the max pressure for maximum fuel economy. When it comes time to replace tires, get something with a smooth tread that's not aggressive. Most manufacturers even post tire weights for a specific size and tire model online. 5lbs a tire = 20lbs less in rolling resistance. if you have any crap in the back of the vehicle that doesn't need to be there, leave it at home. A little weight savings can go a long way. As an example, I used an old grand caravan for commuting (work van) and removed the rear seats, and I gained an extra 55miles a tank just from that alone. Total weight saved was a good 250-300lbs. If you need your seats, that's fine, but it's just something to give you an idea.
A properly tuned engine is another plus. If you use cellulose paper drop in filters, be sure to change it every second oil change for best breathing.
The worst thing you can do is take advantage of the aftermarket products that state they can provide better mileage, but really if they did, it would take you years to offset the costs of buying those products in the first place.
