I have been reading about what you should expect for fuel mileage. I have noticed a steady drop in MPGs over the years. Like 15 years ago I took my 29.5 foot Coachmen on a long trip and got 9 mpg. Now...
Just curious when the diesel industry started to switch to the low sulfur diesel fuel what the impact in MPG was. So now you burn more fuel to get cleaner air along with all the other EPA******added like after burners and the DEF requirements.
Just wonder what pollution is being put back into the environment manufacturing the products to make the engine burn cleaner. I bet the overall picture it's actually made it worse. It's all smoke and mirrors :B
