| | Is there an oversized tank available on these? I think the tanks in | both of my Grands are 20 gallon (I have a 96 and 03). 3/4 a tank at 28 | MPG would get me only 420 miles. I've never heard of a van with a | larger tank. | | | Matt |
I think the most I've ever put in the tank is about 18.x gallons, so it isn't any larger than normal. They used to offer a larger that standard tank (14gals standard I think back then) back in the 80's, but I don't think they did in
1997.
The gauge was registering around 1/4-full at fillup. Went from near Baltimore to North Myrtle Beach and drove around North Myrtle Beach for a day or so without getting gas. What ever the fillup numbers were (and that was 5-6 years ago, so don't remember) the mileage came to around 28 point something. Never got that again, so was a anomaly. I was packed full gear with three kids and running 70-75MPH. Go figure. I will say that, for what ever reason, I almost always get better numbers on the vehicles I've driven than the "ratings" state. That doesn't happen for most people.
The biggest point though is that this time of year is very hard on mileage...especially if most trips are under 10 miles. The engine probably doesn't even get 10-12MPG during those 1st 2-3 miles of a trip when the temp is
10 degrees.
