And is Ryanw821 offering to pay your repair bills or the cost for an attorney to go to court to get Chrysler to reimburse you? If not he should shut up.
GM starting in 2011 had a fuel heater and other modifications so that their engines could burn B20 fuel. But any problems caused from the use of B20 is not covered under the manufacturer's warranty for the engine. Above all else do not switch back and forth from biodiesel and regular diesel. Stick with one or the other.
Per General Motors for their diesel engines:
Owners who have very low fuel usage or who have vehicles stored for extended periods of time should avoid the use of biodiesel. Storage at hot ambient temperatures will accelerate biodiesel degradation.
When vehicles will be stored for extended periods of time (greater than one month), they should be run out of biodiesel to below 1/4 tank, refueled with conventional Ultra Low Sulfur Diesel fuel, and driven several miles before storage.
Biodiesel gels sooner than conventional diesel fuel at cold temperature, and biodiesel fuel requires proper blending for winter time operation. Fuels improperly blended for cold temperature operation may result in restricted fuel filters and degraded vehicle performance.
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.
Avoid biodiesel as much as possible and make use of a fuel stabilizer for diesel if the truck is not going to be used for weeks at a time.
