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.
