Hello, i have been topping up my coolant with regular water and cheap antifreeze but i really dont want to do this anymore so i was wondering if Carplan red organic anti freeze is ok to use? My Mondeo is 1994, Automatic and has 62k on the clock if this helps. The local car spares shop told me to use Carplan red 5 year organic, he said it was fine to use, is this correct and advisable? Thankyou.
