Too many variables for that to have an easy answer. There are winter and summer grades of fuel. If there aren't many diesels around there, you could have picked up a tank of summer grade from a slow moving supplier. > Should plugging in the block heater make a difference? Yes. There are variations in block heaters, too. Maybe your vehicle has one designed for higher temps than yours, fitted to keep the production line running.

DPF equipped vehicles need to be run on longer journeys, mostly, with regular vigorous use to keep the filters working well. -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
