Chevrolet Equinox Owners Manual: Biodiesel

Biodiesel is a renewable fuel produced from vegetable oils or animal fats that have been chemically modified to make it compatible with diesel fuel

Caution Do not use home-made biodiesel or home test kits because the quality cannot be verified by approved scientific methods. Do not use raw vegetable oil or other unmodified bio-oils, fats, or blends of vegetable oil with diesel. They could damage the fuel system and engine, and damages would not be covered by the vehicle warranty.


Caution Do not use blends containing more than 20% biodiesel. Any engine, fuel system, or exhaust after-treatment system damage would not be covered by the vehicle warranty.

Biodiesel fuel quality degrades with time and exposure to high temperature quicker than Ultra Low Sulfur Diesel fuel. More frequent refueling provides the best opportunity to have a supply of fresh fuel. Storage at hot ambient temperatures will accelerate biodiesel degradation.

Owners who use very little fuel, or who have vehicles stored for extended periods of time, should avoid the use of biodiesel blended fuels above 5% by volume. When vehicles are stored for longer than one month, they should be run out of biodiesel to below one-quarter tank, refueled with Ultra Low Sulfur Diesel fuel, and driven at least 32 km (20 mi) before storage.

At temperatures belowC (32 F), it is recommended to switch to Ultra Low Sulfur Diesel fuel with no biodiesel content, or to blends with biodiesel containing less than 5% by volume. At these extreme cold temperatures, biodiesel blends higher than 5% by volume may cause fuel filter plugging and system gelling, which can lead to vehicle operability problems.

Fuels improperly blended for cold temperature operation may result in restricted fuel filters and degraded vehicle performance. GM diesel vehicles are equipped with a fuel heating system to provide an extra level of protection against filter plugging from gelling or waxing of conventional diesel fuel and biodiesel blends. If the operating temperature is far below the temperature at which gelling or waxing of the fuel occurs, the system cannot prevent all cases of filter plugging.

If the vehicle experiences a fuel filter restriction, the on-board monitoring system will alert the driver that the fuel filter requires service. The fuel filter, however, will not prevent all damage caused by poor quality biodiesel.

What Fuel to Use in Mexico
Use diesel fuel specification NOM-086 Pemex UBA, which meets the Ultra Low Sulfur Diesel fuel requirement of 15 ppm sulfur maximum. This fuel is not available in all regions of Mexico. Ca ...

Cold Weather Operation (Diesel)
In cold weather, the fuel filter may become clogged by wax naturally present in the fuel. To unclog it, move the vehicle to a warm garage area and allow the filter to warm up. The fuel filter m ...
