I live in the country so use oil fired heating. Noticing a strange smell from the boiler I looked and found 1/2 inch of heating oil in the bottom, with the boiler running! Getting to the point the pump had leaked due to the seals failing by going hard and shrinking because there is now biofuel mixed in with the heating oil. Sure enough the new pump is marked up as biofuel friendly even with the word BIO cast into the body. The heating engineer said this is a regular job for him these days.
So its got me thinking about my diesel car, are the pump, solenoid and injector seals in that good for biofuel addition in the diesel or we all suddenly going to find older diesel cars needing the fuel systems replacing? A Google for anything on the subject only came up with manufacturers talking about seals able to stand up to biofuel. Anyone know if this is something to be concerned about or have car manufacturers dealt with this.
