To be able to do a decent comparison for the 10 day period I went and looked at my numbers for the time period of May 18-28th in 2011, and 2012 to compare the difference with the numbers since I have installed the gauge.
Back in 2011 for that time period I averaged 6.77 mpg. All but one of my fuel ups showed light loads with there being a total of 7 fuel ups for that time period.
In 2012 for that time period I averaged 6.54 mpg. All but one of my fuel ups were heavy loads pulling the hills from Illinois to Oklahoma. At that time I was running on our dedicated Lowes account so I had a consistent route. I showed 5 fuel tickets for that time period.
These last 10 days I averaged 7.00 mpg. I showed 3 heavy tickets, one medium and the others light. I had 8 tickets for that time period. I made multiple trips through the Appalachian mountains with both heavy and light loads.
Taking that into consideration, I have to say in the last 10 days on average my fuel mileage has increased by 4/10 of a mile when comparing them to the other two periods. It could be more than that when you really think about it.
Another thing I discovered since I put in a few of the PID codes the manufacturer sent back to me is I can now tell when my truck is doing a passive regen while driving down the road. I watch my DPF temperature. I have found it runs up to 1100 degrees in a cycle that can last up to 30 minutes. When this happens I notice a pretty good drop in fuel mileage of up to 2/10 even if your on nice even flat ground. So a person just has to keep this in mind when they are running and know they have to make that ground back up.
Great info. I appreciate knowing how it worked for you, and knowing how the regen effects mileage is very helpful too.
