Most 1.2/1.4 8v's came with the 91/95RON plug which can be reversed depending on what fuel you use. makes a difference if the RON plug is set to 95 and you use 95, not even sure you can still get 91 in the UK, can you? Vauxhall can supply a RON plug which is 95/98 if you want to take advantage of Optimax etc. wil advance the timing to suit the engine :thumbs:

	pointless running super on a 1.2 8v octane plug only used if running low-octane fuel in the eu (92RON,. etc) if you runb 95+ then leaving it on 95 is fine... if you run 95+ with the plug set to 92 then it will just fcuk it all up

	Does anybody actually adjust this to what grade they are using. I am running super unleaded which is 98 ron but have not changed the plug on my 1.2 8v spi. Will this effect the way in which the car runs?
