I just had my Zafira serviced at a Vauxhall main dealer yesterday. The service was costed at 144.50 UKP, but just looking at why the total bill was so large they've charged 40 quid for oil!!! I've had good service from two Vauxhall dealers, with no complaints so far. Does anyone know what the retail cost from a dealer is for that amount of oil? I bought a litre bottle from the dealer once, didn't seem so expensive to me.
