Does anyone have any idea(s) what this current debacle with the contaminated fuel is going to do to O2 sensor prices? I was planning on replacing mine on our X reg zaf 1.8 soon anyhow, but I heard on the radio that Vx have sold so many that they are now on back order! Will the prices go up due to rarity value? if so will they plummet with an (eventual) glut of them on the market from manufacturers? And has anyone on here had to replace any sensors because of this?
