Due to filling my diesel tin-top to the brim with unleaded (DOH!) I have 50 litres of unleaded in the garage, so if I get a minute over this weekend I will do the measurement. A quiet day at work this morning means I have designed the circuit - I've even put in some feedback which allows me to squash and pull the curve if the ohms/litre is not a linear scale.
btw. a 2011 Passat CC diesel will actually run on unleaded - but not very nicely (I got it 9 miles home). It smelt very bad and got awfully hot. Good job I only have to keep my company cars for 6 months - some poor soul will buy that off a VW forecourt as "nearly new".
