For diesel-fueled vehicles, you’ll be glad to know we are as dedicated to the
quality of our diesel as we are to our gasolines. That’s why we develop diesel
fuels for engines that:
-
Provide energy for power
-
Provide good fuel economy
-
Allow easy start-up
-
Flow readily in cold temperatures
-
Protect the fuel delivery system
-
Provide low emissions
You’ll find one of our diesel fuels at many service stations across the United
States, and you can be confident that they will perform to meet your needs –
as well as your expectations.
Ultra
Low Sulfur Diesel Fuel No. 1
Our Ultra Low Sulfur Diesel Fuel No. 1 is usually often used as a blending
component to winterize the No. 2-D grade. This is the fuel you should use if
you live in an area with abnormally low temperature conditions. Compared to
the No. 2-D grade, our Ultra Low Sulfur Diesel No. 1 has a lower viscosity,
and generally provides higher cetane number and better low-temperature
operability for your vehicle. The sulfur content of ULSD No. 1 is 15 parts per
million (ppm) maximum.
Low Sulfur
Diesel Fuel No. 1
Low Sulfur Diesel Fuel No. 1 is similar to the Ultra Low Sulfur Diesel Fuel
No. 1 except that its sulfur content is higher than 15 ppm. This diesel fuel
must not be used in 2007 model year and newer vehicles/engines. Ultra Low
Sulfur Diesel Fuel No. 1 must be used in those vehicles/engines.
Ultra Low Sulfur Diesel Fuel No. 2
Our Ultra Low Sulfur Diesel Fuel No. 2 was formulated to be used by any
diesel-fueled vehicle on the road today-including yours. Compared to the No.
1-D grade, our Low Sulfur Diesel No. 2 provides higher fuel economy, power,
flash point, viscosity and lubricity for your vehicle. ULSD No. 2 must be used
in 2007 model year and newer vehicles/engines to protect the performance of
the emission controls.
Low Sulfur Diesel Fuel No. 2
Low Sulfur Diesel Fuel No. 2 is similar to the Ultra Low Sulfur Diesel Fuel
No. 2 except that its sulfur content is higher than 15 ppm. This diesel fuel
must not be used in 2007 model year and newer vehicles/engines. Ultra Low
Sulfur Diesel Fuel No. 2 must be used in those vehicles/engines.
For You, Your Vehicle And The World Around You
In order for your
vehicle’s diesel engine to start easily, the fuel must have a sufficiently
high cetane number. All of our diesel fuels meet the minimum cetane number
requirement of 40 to ensure easy start-up for your vehicle. Values above this
level haven’t proven to significantly improve your engine’s performance.
And, all of our ULSD and LSD fuels contain lubricity additives to improve
protection against wear.
Our commitment to providing you with quality diesel fuel doesn't stop at the
refinery. We check the fuel at key points as it is transported through the
distribution system to your vehicle. Should you ever have a problem with your
vehicle that is related to the fuel quality, we invite you to call our
Customer Assistance Center at 1-800-662-4592. Even if you just want to ask a
question or share a comment about our products or services, feel free to give
us a call.
