Well, not everything produced by the dealer is the best quality and I am not very knowledgeable when it comes to engine oils, basically know nothing, so just needed an advice as there is plenty contradicting info online, that's all Brian.

So what you are saying guys is paying extra £70-£80 for 25 litres of Castrol Edge vs Quantum is basically mugging yourself off??

Ok then, I will get 25l of Quantum Longlife III 5W-30.

Last question
How about Quantum Platinum 5W-40?? Is it a better option for cars with higher mileage??

Pug, what I will do then is only one flush at least.
I will drain the oil, put new filter and new oil inc engine flush, run it for 20min, drain oil and change the filter and oil again.

Thank you once again boys for all the advice and comments
