Hi I have a vectra 2003 1.8 16 v, and I am wondering what tool I must use to remove my sump plug if any one could tell me please. Also I have bought 5W 40 fully synthetic oil, I hope this is the right one, could any one confrim this? I looked at halfords, and for some reason the oil filter they quoted looked like a paper type, similar to an air filter? yet looking on my engine, I can clearly see a normal oil filter, and my local motor shop also agreed a normal oil filter was required, not sure if halfords have their books label wrong or what? thanks
