InnoMetric Fuel Efficiency Testing: Get Real-World Answers for Real-World Cost Savings

Until now, the trucking industry has been stuck relying on outdated test methods to measure fuel savings. Those methods have many flaws, including accuracy problems and their failure to provide truly useful and reliable answers for real-world operations. InnoMetric’s fuel efficiency testing is different – and better in ways that drive significant value for today’s truck fleets.

Multi-point data acquisition feeds our proprietary analytical methods 

Our fuel efficiency testing solves accuracy issues and quickly delivers clear results that drive confident business decisions for actual fleet operations. This allows fleet management to see the true savings of any product, spec, or adjustment in their fleet and make decisions that bring them the most benefit.

Choosing a fuel efficiency product or spec that saves even ½ percent equates to thousands of dollars over the life of a vehicle. No other test methods have the accuracy to measure that precisely, or the analytical tools to predict what it will save in real-world operations.

That is why InnoMetric’s fuel efficiency testing methods are so powerful for a fleet’s financial bottom line.

Faster and Easier Testing with Rapid Payback

Our testing is fast and easy. We know fleets are busy keeping their trucks moving so we always minimize disruption to your operations.

InnoMetric finds the fleet’s easiest savings, meaning the easiest to implement, purchase, or pay back. We provide whatever testing suits you, fully customized to your needs.

Our clients experience rapid payback on our fuel efficiency testing services. Usually just a matter of days based on common optimization recommendations.

InnoMetric testing uses the fleet’s vehicles and drivers, normally based out of the fleet’s terminal. We test on highways near the terminal or we use a private track. Our testing is very flexible due to the sophisticated equipment and analytical procedures we use. This makes it easy to conduct fuel efficiency testing almost anywhere and any time of year.

Typical Testing Scenario


  • A bit of shop space, one tech at most, and one or two drivers during testing.
  • InnoMetric engineers install our test equipment at the fleet’s terminal (1-2 days) on one or two trucks with some assistance from a tech who is familiar with the shop and shop practices.
  • Once we are set up, only drivers are required and a tech to make equipment modifications when necessary. We test on either local highways or tracks.
  • There is no weighing fuel, tracking miles, or monitoring maintenance.

Tests usually only take 2-3 hours. We can test multiple things in one day and as many as 25 areas in an average week.

What We Test

We can measure the fuel savings of anything on a truck or trailer, from bumper to bumper, top to bottom, providing answers for your fleet’s unique real-world operations. Testing can be for new purchase decisions or part of a fleet’s MPG improvement program. We can also perform multiple tests in a single day, from multiple categories such as aerodynamic, tires, or lubricants. If you don’t see what you’re looking for in the list below, just ask.


We can test any aerodynamic component or adjustment, of any size or shape, for the truck or trailer. Aerodynamic drag can equate to half of fuel use at highway speed, making aerodynamic improvements a major savings opportunity.

  • Trailer
    • Skirts
    • Rear devices, boat tails
    • Under-tray systems
    • Nose cones
  • Truck
    • Tank fairings & extensions
    • Roof cap & extensions
    • OEM aero kits
    • Cab extenders
    • Side kits
  • Other
    • Wheel covers
    • Mud flaps
    • Vortex generators
    • Mirrors
    • Etc… the list is nearly endless
Savings Tip: Every decision counts with aerodynamics, and 20% improvements are common today. Payback and profits vary for add-on products, however, for items already in use, making the optimal decision can boost fuel efficiency 1% – 5% with no additional costs – an instant payback! Results from trailer skirts alone can vary by 2% or more.


We can measure the fuel savings of any tire, brand, or combination. Tires can represent up to 30% of fuel use on trucks, which makes tire selection a critical savings opportunity for a fleet to be aware of.

  • Compare tire brands (new and retread)
  • Compare tire models
  • Dual vs. Single tires
  • New vs. retread tires


Savings Tip: Fuel savings from tires are one of the most profitable and fastest payback options available to fleets today. They can also be one of the easiest, from both operations and financial standpoints, because tires are already being purchased and installed. There are many options available to fleets, whatever the requirements. It’s not just about using super singles or using a certified low rolling resistance tire.

Fuels and Lubricants

We can compare the fuel savings of any type of fuel, lubricant, or additive. These can be simple, easy, and very profitable areas for fuel savings that most people are unaware of.

  • Diesel fuel brands
  • Biodiesel brands and blends
  • Lubricant brands
  • Lubricant viscosities
  • Additives (fuel, oil)


Savings Tip: Fluids have come a long way in recent years and there are gains available that can have an immediate payback, reducing maintenance costs and labor. Legitimate products in this category do exist. However, be wary of ‘snake oils’ and over-stated claims since this is a common area of exaggeration. Also be aware that improvements are nearly impossible to detect during normal operations – even though they may be occurring – so don’t be surprised if you try a product and get inconsistent results when tracking fuel mileage. High tech testing is critical with fuels and lubricants, and can get a fleet saving much sooner.

Trucks, Truck Specs, and Add-ons

We can compare the fuel savings of any trucks or specs, which enables fleets to make purchase decisions faster, easier, and more precisely. We can also test any add-on technologies that may save the fleet money.

  • Truck brand and model comparisons
  • Aerodynamic options (listed above)
  • Engine/Drivetrain
    • Transmission (brand/gear ratios/shift patterns)
    • Engine (brand/displacement/rating/tuners)
    • Differential (ratio, 6 x 2, brand)
    • Fuel system add-ons
    • Intake system add-ons
  • Tire comparison (listed above)
  • Miscellaneous product add-ons


Savings Tip: The biggest cost over a truck’s life is fuel – even with a 3-year truck life cycle – which makes fuel efficiency data critical to purchase decisions. With advanced vehicle testing adopted from other high tech industries, truck fleets can now get the data they need. Also, high tech testing doesn’t require months of tracking a truck candidate’s fuel mileage, or purchasing multiple trucks the fleet is then stuck with. It also allows each spec option to be measured individually, rather than testing a complete truck package, which allows the fleet to optimize fuel savings over the life of the vehicle.

Trailers, Trailer Specs, and Add-ons

We can compare the fuel savings of any trailers, specs, or add-on options on them. This helps fleets with trailer purchase decisions, as well as choosing the best specs or add-ons for their company.

  • Trailer brand comparison
  • Aerodynamic options (listed above)
  • Bogey and axle options
  • Tire comparison (listed above)


Savings Tip: When done right, spec’ing the right add-ons for trailers can save more in fuel than the cost of the trailer (for a box van trailer). The main areas are aerodynamics and tires. Retreads can be especially important since they are very common on trailers and vary significantly in fuel efficiency. Fuel savings from tires are even greater with heavier loads.
