No one doubts the importance of regular oil and filter changes, regardless of the type of vehicle they may own or service. And more knowledgeable folks also understand the importance of regular changes of the lubricant in other driveline components like the differential. But even regular changes of lubricants and filters cannot remove deposits of sludge, gum, varnish and other contaminants that build up over time.

">Since you can't physically sit beside your drivers all day coaching their driving habits and performance, some sort of monitoring tool can be useful. However, if drivers see such devices as annoying or impeding their ability to drive, they won't happily accept the intrusion. A technology company in Pittsford, N.Y., has found a happy medium: a monitoring device that encourages drivers to do better without getting on their nerves or taking away drivability, while providing back-office data that helps fleets coach and instruct drivers on better driving habits to save fuel.
I recently paid a visit to Vnomics and saw how its engineers and developers had adopted the True Fuel technology from a military application. I also spent several hours in a test truck proving the system's ability to coax — rather than coerce — me into the green zone.
It's a simple system on the surface, with a huge amount of functionality built in.
The in-truck hardware consists of a reader that plugs into the truck's data port with a Y-cable (to keep the connection free for other applications such as electronic logs), and collects data on vehicle speed, power demand and engine operation. Each device is matched to the components on that particular truck. It reads sensor data from the ECU and sends it to the terminal in bursts via a cellular connection. There's no display to distract the driver; a tone is used to alert him or her to behavior that is problematic. The box is about the size of a paperback novel and it can be installed on or under the dash in less than 15 minutes.
I'll skip over the intricacies of the back-office software. Managers see only a very straightforward interface that shows driver performance and historical trends as well as current and previous trip data. In addition to evaluating driver performance. True Fuel can compare truck performance and fuel consumption information and identify underperforming or improperly spec'd trucks.
Much of what makes this work so well is how Vnomics interprets and displays the data. Embedded in the system architecture are the engine's fuel maps as well as the specs and ratings to aid in interpreting the data. Layered over that are driver and environmental information that the system uses to determine if the engine is being operated as efficiently as possible. For example, the system knows if the truck is 400 or 450 hp, whether it's empty or loaded, on flat ground or on a hill. That's all significant, as the driving technique might be different in each case.
It doesn't use fuel consumed as a driver-rating parameter, but rather potential fuel economy: Given where you are operating on the fuel map, how close did you come to using the least amount of fuel needed to generate the required power for operation? This immediately deflates any arguments about driver fuel economy rankings being unfair because they are subject to external influences. It's really about whether or not the driver is operating the truck correctly.
Ben Stevens, Vnomics' sales engineer, explains it this way. If one driver is getting 7.2 mpg out of an algorithm-determined potential of 7.5, he's within 4% of the target, which isn't bad. However, another driver might be getting 6.1 mpg out of a potential 6.2.
In testing Vnomics True Fuel, I made two runs over the same course, mostly stop-and-go driving with a little freeway time. We were bobtailing in a leased tractor with a manual transmission (the system works equally well on automated and automatic transmissions, too). I don't think the fact that we were bobtail matters, because again, the system was watching performance, not fuel consumed.
For the first run I put my bad driver hat on and deliberately drove as poorly as I could — hard braking, idling too much, taking gear changes to wildly high rpm, running in the wrong gear, etc. It was so against my nature to drive like this that I really had to work at it.
My score was a 46 out of a possible 100. I thought it would be much worse given how badly I was behaving. Stevens told me he has seen drivers with scores in the low 20s. I can't even imagine how badly you have to screw up to earn a score like that.
Run 2 was the Good Jim run. I diligently tried to keep the revs down, accelerate gently, minimize idling, skip gears, etc. I did pretty well, causing the alert to sound only three times for a score of 99.
Incidentally, each of the three times I messed up and over-revved a gear, I was talking to Ben. This was a real an eye-opener for me. The conversation distracted me from concentrating on my shifting. I can certainly drive properly when I'm thinking about it, but I could never maintain that level of concentration all day long.
And that may be the real benefit to True Fuel. A good, diligent driver gets a gentle alert from a not-unpleasant-sounding beep to remind him or her that they are slipping. That's a lot easier to take than finding out at the end of the month that you blew your fuel bonus.

Diesel fuel prices are continuing to fall, dropping around 8 cents from their peak of $2.43 per gallon in early June, according to the latest numbers from the Energy Department.
The average price of a gallon of diesel fuel fell 3.1 cents last week, settling to $2.348 per gallon at the pump. While prices have been dropping, the gap between 2015's and 2016's prices has been shrinking. Last week's prices were 32 cents cheaper than in the same week a year ago.
When broken down by region, the largest decrease in prices occurred in the Central Atlantic, where prices fell by 4 cents. The smallest change was in the Rocky Mountain region where prices fell 1.5 cents.
Gas prices also fell last week with the average price of a gallon of regular gasoline dropping 2.3 cents to $2.159 per gallon. The price is 53 cents cheaper than it was for the same week of 2015.
The largest drop in prices was in the West Coast region, where it dropped 5.6 cents last week. The smallest change was a 0.3-cent drop in the Midwest.
The crude oil market has also been down in recent weeks, with the price of a barrel of crude dropping to around $40, according to a Market Watch report.
Crude oil prices had been on the rise since bottoming out earlier this year. But new fears that the global supply glut would not be going away has had a sobering effect on the oil market.
Global demand for oil has dropped in the past year. However, rather than limiting supply to adjust for weaker demand, OPEC members and other major oil-producing countries have resolved to increase production.

Dill Air Controls has launched a complete truck valve installation toolkit, responding to feedback from fleets and service technicians.
Dill's research and development team worked with the trucking industry to figure out installation issues to gain an understanding of the common causes of valve stem air leaks. Dill designed the complete truck valve installation toolkit based on the results of its efforts.
“We were humbled by the support and feedback from major trucking companies as we worked to bring awareness to a problem as old as our industry can remember. The resulting toolkit enables any technician or servicing facility to clean, measure, and accurately torque valves to specifications as set forth by The Tire and Rim Association,” said Larry Schlesinger, Dill's chief engineer and tire and rim association tube and valve standards committee chair.
The toolkit includes a cleaning brush, Go/No-Go measuring tool, preset torque wrenches and a T-handle hex wrench to hold the base of the valve stem from spinning during tightening. Dill's 5720 kit is equipped to handle the variety of valves used in alloy and steel truck wheels.

Fleet Advantage's quarterly Truck Lifecycle Data Index shows that in the second quarter of 2016, replacing 2011 model-year trucks with 2017 models will save fleets around $18,861 in the first 12 months of operation.
This is over $700 more in savings over the first quarter numbers, reflecting a 9% increase. Rising fuel prices over the past few months contributed to the increased savings realized by the more fuel efficient 2017 models.
While the biggest benefits are seen by replacing the older models, replacing a 2015 model-year day cab with a 2017 model will still net $5,964 in savings over 12 months. The savings calculations are based on an operation running 100,000 miles per year and were compiled from Fleet Advantage's' ATLAAS analytics software.
“It's clear that upgrading to a new truck provides significant benefits for fleet managers looking to strengthen their bottom line, and that fleets utilizing a shorter vehicle lifecycle will secure a competitive advantage.” said Brian McMahon, data analyst at Fleet Advantage. “First-year savings are impressive and rise exponentially when multiplied across dozens of truck units.”
The report also shows that fleets can see emissions and fuel usage reductions of 14% when replacing 2011 models with the latest trucks.
