2303 11/15/2006 8:15:36 AM 11/17/2006 Michael Day mday@hughes.net new diesel fuel Larry, I have a 1992 Newell with the 500 hp 8V92 and the HT740 4 speed transmission and weighs about 43,500 pounds. I get about 6 mpg with the 12.5KW generator running. That would be about 6.25 mpg without the generator. The Series 60 powered Newells had the Allision 6 speed transmission and got better fuel mileage. In recent years the power has gone up as larger engines have been installed, the weight of the coaches has increased over 10,000 pounds from mine, and some of the coaches are now equipped with the 10 speed ZF transmission. All of these factors, power, transmission and weight, affect fuel economy.
