Just got back from an MOT. Failed on my lambda sensor readings being slightly elevated. Guy in Kwik Fit recommended a can of BG's 44K (£20), then an hours drive before returning for retest. Took the chance, added the fuel supplement and retested for a pass

Apparently it last for a year and can help fuel consumption/power. I'll take that with a pinch of salt, just glad she's passed for another year!
