So my m8 noticed the other week there was bit of oil round my can cover. so i took it to vauxhall and showed them n they looked at service book and said im sorry we cannot help u cus the car has not been serviced by vauxhall or hasnt has genuine vauxhall part used. iv owned the car a month! Gits. So bought the rocker cover gasget £15 il do it maself. Where do i stand on servicing. i was told if u use genuine vaux parts then its covered no matter who services it. so should i go get a genuine Vauxhall Oil Filter and try at another garage??
