Fuel Saving Tips
Diesel injectors are very delicate parts. They run at very high pressure and have tiny fuel passages that can get clogged decreasing efficiency. Using a cleaning additive occasionally can clean the injectors and prevent costly repairs (if they get clogged so much that they stop working). Warning: only use cleaning additives if you always used them since the car was new and you changed the diesel filter regularly. Otherwise you may free some gunk from the filter or fuel tank and clog your injectors.
