My mate nearly rounded off the drain plug which is shaped like an allen key, fortunately he stopped before this happened. 

Which has resulted in me not getting my gearbox oil changed.

Anybody know the correct size I need to undo this or where I can purchase the correct size from?

Cheers

Have a 1.7 diesel Astra J 62 plate. I am planning on changing the oil and filter weekend.

Can anyone tell me:

2) What specification I should be looking for on the back of oil bottle?

3) How many litres it holds?

Thanks again guys cannot find my manual.

Hi was going to change engine oil on my 1.6 le should 5 litres be enough.

Ok, prepping for a trip down to Alton towers leaving tomorrow, and this morning it change oil soon popped up.

I'm about 650 miles round trip, add on 300 for miscellaneous other driving, looking at 1k miles before I can get back and do the oil change (procrastination will be the end of me)

Hi all
I have Opel Astra j gear box af40, what is the  best oil for this gear box ??

Hi, I've got a couple of Astra J's, both 1.6 petrol
one has started a to leak a little oil - it doesn't seem to drip on the floor but the sump is wet - the drips fall onto the exhaust while driving (I love the smell of burning oil in the morning)

I've taken off the manifold heat shield and the front of block is also damp, so its not the sump gasket or the head gasket.
Is it likely to be the oil pressure switch?
Is this a known fault?

Alright,

Looking to change gearbox oil in my 2011 2.0 CDTI. 
From Rustys list I've got that its an F40 box and needs 1.5 ltr oil.

Question is, which oil?

I can remember reading somewhere not to use the same oil as from the factory (too thin?) but I can't find the info again.

Grateful for any help.

Cheers.
