    Plan to get a coolant top up from Shell as according to the manual the Long Life Shell OAT coolant should be compatible, but there are 2 types available from the petrol station:

    1. Shell Easycare Longlife engine coolant (up to 250000 km) Pink colour

    2. Shell Easycare Premium engine coolant (up to 60000 km) Blue Colour, not recommended to mix with OAT based coolant.

    Does it mean the long life Pink colour is the one to get as there is no caveat vs not mixing with OAT coolant?

    Halfords- website- paraphrasing but you can read it yourself– Cars made after 1998 +/-  normally need antifreeze /coolant that uses silicate-free, organic acid technology (OAT). These types of antifreeze offer better corrosion protection so that parts don’t need to be changed as often. Cars made before 1998 usually need antifreeze that isn’t OAT-based and that does contain silicate.

    I was always taught –Whilst colour isn’t always necessarily an indicator of chemistry PINK is generally  OAT and BLUE not- AND not to be mixed together
