Well I went into my local VW Dealers the other day to book my car in, so they can diagnose the rattle from my engine when cold.
I was waiting aroung and I noticed that all the shelves that used to have Castrol on, have now been replaced with Quantum Oils.
The longlife 5-30 was £35 for 5L. When I enquired they said it was as good as the Castrol Edge 5-30, just alot cheaper. I then asked that when I have my next service, can I have Castrol or supply my own Castrol. The guy said no, and that was that.
Has anyone heard of this Quantum? Is it any good? Do you think I should go elsewhere that does Castrol, or should I see the service manager and ask him to use Castrol?
