I'm on fixed annual servicing and just had my second service carried out at 17K, surprised to see on invoice they used Castrol Magnetec, don't know exact spec , just states Synthetic.
Not overly concerned, but just wondered why they wouldn't use Quantum.
This is the second and last service on the service plan that was included (due to taking finance, which i paid straight off) so it was effectively free.
Next change will be in 12 months and around 6-7K.
Any thoughts on why Castrol? or concerns?
