Från vad som skrivs på wikipedia om motorn
http://en.wikipedia.org/wiki/PSA_XUD#Vegetable_oil_fuel så verkar det som att de annars bör kunna tåla RME (bio-diesel)
Citat:
Heavily used oil may be highly acidic and corrode the inside of the injection pump. Such oil can only be used as fuel without the risk of damage, if it has been chemically processed into bio-diesel. The open market price for used oil often quite close to special offer supermarket prices for new oil, which can be used straight away. In order to reduce the viscosity of the SVO, it should be heated to engine coolant operating temperature, typically with a two tank system, in order to start and shutdown on diesel or bio-diesel. Versions of this engine from the early '90s onward, are typically fitted with a Peugeot-type coolant heated fuel filter that helps heat fuel and reduce viscosity. Fuel / engine coolant heat exchangers, usually required for straight vegetable oil conversions, are still needed for long term life expectancy, or there will be accelerated wear of the fuel injection pump.
