Petrol will not degrade the seals, if you go on to any biofuel forum you will find it is common practice to blend petrol with biodiesel or SVO/WVO this time of year. I have never seen a report of petrol causing problems. Tests prove that 10% petrol halves the viscosity of vegetable oil. Indeed, many car manufacturers will state in their handbook that a certain percentage of petrol can be used to winterise diesel fuel (although not so much these days with the advent of common rail).
Again with 12v fuel heaters, the general advice on any biofuel forum is that they are a waste of time. The amount of current you have to draw at 12v to make any significant difference is huge. You have a flow rate of around a litre a minute. There are systems that use glow plugs to heat the fuel, but they are complicated and they have question marks over their safety. Why bother when you have a coolant to fuel heat exchanger already built in to the filter housing from the factory? All it needs is a simple modification to the thermostat and you have fuel heated to 45 degrees within 2 minutes of starting, plenty hot enough.
