Commercial Diesel Fuel in Michigan

Creating Tomorrow’s Diesel Fuel Today

We are proud to provide our agricultural and commercial accounts with Smith Ultra Diesel on and off road. Smith Oil & Propane has formulated a proprietary diesel additive that when added to ULSD will upgrade the performance of the diesel to meet and exceed the performance of Premium Diesel.

Protect your investment with cutting edge technology. Smith Ultra Diesel now has SYNSHIELD™, a proprietary lubricity additive, blended with Smith Ultra Diesel, that surpasses industry standards when it comes to lubricity in fuel. SynShield™ is one of the few lubricity additives that exceeds EPA’s new standard and it does NOT contain sulfer.

Smith Ultra Diesel Benefits:

Improve MileageImprove HorsepowerIncreases CetaneReduces Emissions

Improves Fuel LubricityCleans InjectorsInhibits CorrosionControls Moisture

Boost Cetane up to 6 Numbers
New Advanced Injector Cleaning Technology
Decrease Fuel Consumption up to 8% and Increase Power
Contains Slickdiesel for Maximum Fuel Lubrication
Superior Cold-Weather Operability

Boost Cetane up to 6 Numbers

Cetane is a measure of the ignition quality of diesel fuel. Diesel fuels with higher cetane numbers result in smoother running engines with less power lags and faster cold starts. Smith Ultra Diesel + Cetane Boost is an additized fuel that provides the cetane level diesel engines require to run at peak performance.

New Advanced Injector Cleaning Technology

Smith Ultra Diesel + Cetane Boost has been formulated to contain the most advanced injector cleaning technology. This technology provides maximum injector cleanup of injection deposits in all fuel injection systems, including High Pressure Common Rail (HPCR) systems installed on 2007 and newer engines. The engine operational improvements are significant:

Decreased fuel consumption up to 8 percent: Fuel savings exceed cost of additive
Increased power and reduced need for downshifting
Smoother and quieter engine operation

Decrease Fuel Consumption up to 8% and Increase Power

A clean injection system is the key component to efficient engine operation. This system burns fuel more completely, which results in an increased amount of power and up to a 8 perfect reduction in fuel consumption. That equates to 8 FREE gallons of diesel fuel with every 100 gallons of diesel fuel you use.

Contains Slickdiesel for Maximum Fuel Lubrication

Slickdiesel sets the standard for lubrication of diesel fuel injection systems. The components of diesel fuel-injection systems are lubricated by diesel fuel. Without proper lubrication, fuel injectors and pumps are subjected to increased wear rates and premature failure.

High Frequency Reciprocating Rig (or HFRR) is the ASTM standard for evaluating the lubricity of diesel fuels. The test measures the lubricity, which is the ability of a fluid to effect friction and wear between surfaces in relative motion under load. The test was developed in conjunction with the transition to Ultra Low Sulfur Diesel (ULSD) fuel, because the dramatic reduction in sulfur negatively impacted the lubricity of the fuel. The results of the test are recorded as measurement of Wear Scar Diameter or WSD. The larger the WSD, the less lubrication qualities of the fuel. The maximum WSD permitted by ASTM D975 is 520 microns. The Engine Manufacturers Association (EMA) recommends a 460 micron WSD.

Superior Cold-Weather Operability

Ultra Diesel + Cetane Boost provides effective reliable cold-weather operability.

In winter, Ultra Diesel + Cetane Boost:

Prevents fuel gelling in temperatures as low as minus-40F.
Keeps fuel liquid during extended engine shutdowns.
Equals performance of a 50/50 blend of No. 2 and No. 1 diesel fuels.
Lowers the Cold-Filter Plugging Point (CFPP) as much as 36F, which keeps fuel filters from plugging with wax.
Protects against fuel-filter icing.
