Disappointed in 2013 Cooper Countryman (petrol) auto. Changes down far too often in inappropriate circumstances - e.g. slight rises at 70ish on motorways and other situations where using flappy-paddle manual to force upchange is accepted and not overridden by auto. Noisy, fussy, and possibly uneconomical, progress unless constantly working gearchange. Hardly the point of auto, and this is my 5th (2 Volvos, Mercedes and BMW).

Dealer and MINI UK not too interested so in desperation I brimmed tank (always use non-supermarket fuel) from 7/8ths empty with Shell V-Power. Almost immediate improvement to auto behaving close to expectation, far less fussy, smoother, more responsive to driver inputs. At last a pleasure to drive. Is it me, or can V-fuel do this?
