The Series 60 Newells seem to get the best mileage. I have an early 90's with the 8V92 and I get about 6 mpg. I have a number of friends with Wanderlodges and the same engine that get about 5 to 5-1/2 mpg. The Series 60 made a significant improvement in fuel economy. The Series 60 were installed in some of the 1994 model Newells. Most Newells from 1995 until 2005 had the Series 60. Remember that as slides were added, the weight increased. A 1995 had a GVWR of 46,000 pounds, 1999 was 50,640 pounds, a 2006 was 59,580 pounds and a 2009 was 63,600 pounds.
Driving speed will make a tremendous difference in fuel mileage. Stay down around 55-60 and you will see dramatically better mileage than at 65-70. Above 70, you are over running your tires anyway.
