DURAMAX Diesel Engine (LML/LGH) - 2011

9-24 Driving and Operating

Your vehicle is equipped with a

fuel heating system to provide a

level of protection against filter

plugging from gelling (waxing)

of conventional diesel fuel and

biodiesel blends. However, the

system will not prevent all cases

of plugged filters if the operating

temperature is far below the

temperature at which gelling or

waxing of the fuel occurs (cloud

point).

Use of biodiesel blends greater

than B5 (5% blend) should be

avoided in cold temperatures.

.

Vehicles operated for extended

periods of time on conventional

diesel fuel and then switched to

biodiesel blends may experience

premature fuel filter clogging and

require more frequent fuel filter

service.

With long term use of

conventional diesel fuel, gum

and varnish may be deposited

within the tank and fuel system.

These deposits, while not

problematic with the use of

conventional diesel fuel, may

become loosened with a sudden

switch to biodiesel blends and

cause fuel filter plugging.

This vehicle is equipped with a

fuel filter restriction monitoring

system that will alert you if the

fuel filter requires service, but it

will not prevent damage caused

by poor quality biodiesel.

.

Use of biodiesel blends will

degrade the performance

of your vehicle’s water

separator. Biodiesel reduces the

effectiveness of the vehicle’s

water separator, and in the event

of water contamination of the

fuel, increases the risk of

damage to the fuel system.

What Fuel to Use in Mexico

Notice: Use of diesel fuel other

than Ultra Low Sulfur Diesel

(15 ppm sulfur maximum) will

cause permanent damage to the

exhaust after‐treatment system.

This damage would not be

covered by the vehicle warranty.

Ultra Low Sulfur Diesel fuel is not

available in all regions of Mexico.

Refueling

Diesel fuel can foam when you

fill the tank. This can cause the

automatic pump nozzle to shut off,

even though the tank is not full.

If this happens, wait for the foaming

to stop, and then try filling the tank

more slowly. See Filling the Tank on

page 9‑33.
