    Some help with Oil change on Mk4?

    Hi guys,
    I am a total novice at car maintenance.
    I have managed to get my spark plugs and air filter changed on my 1999 Opel Astra Mk4, and now want to learn to do the oil change myself.

    I bought the spare oil, oil filter and oil wrench today.
    I am following the guide to change the oil but am getting stuck on step 1

    Here is a pic of my oil tank from underneath.
    Can someone tell me which one of these is the sump plug?
    I presume its B because I unscrewed A and nothing flowed out.
    I tried with all my strength to unscrew B with a wrench but the fecker wont budge.

    hey mate, yeah its B, A is just where the sump is attached to the gearbox... and yeah sump plugs can be a bugger to get off, whack a bit of heat on it and maybe some penetrating spray on the underside of the plug, mite help loosen it abit good luck!

    Thanks scrim
    I've given up for the day, will have another go again next weekend with a bit of heat\oil on it this time. Will also need to attend the gym during the week in prepartion

    One other thing, is replacing the sump plug with a new one mandatory when doing an oil change, what's the danger if you dont?

    You really only need to replace it if the head is getting worn and the spanner wont grip it properly, I have never replaced mine and I have done about 8 oil changes or so.

    Forgot to say I have always put a new rubber o ring on the sump plug everytime I have done the change, your sump plug looks slightly different to mine so not sure if you need to do this or not.

    I usually just get it from vauxhall when I am getting my filter etc, some of them use a metal washer instead though.

    What engine is yours? I am not sure which which but I am sure someone else will.

    Mines a 1.4 petrol (Opel)
    I suppose when I eventually get mine off, I can see what type of one is on it.
    It could be re-usable?
