They will smell you before seeing you!
19p a litre though is very tempting!
ahaha..is it legal?
My mate used to run his 205 on cooking oil, into Lidl every week for £15 of cooking oil. Would last him all week, although it did smell a bit but that didnt bother him as he was saving a fortune.
As said I believe the older diesel engine are able to run on the stuff without any mods
