“As a young man I 'discovered' Duckhams Q20W50 and the combination of their racing involvement along with the unique quality green colour of the oil and it's also unique smell 'sold' me! I have mainly only used Duckhams over the last fifty plus years and never been disappointed, except when no doubt for chemical evolution reasons the evocative smell has gone!”
