in the service manual it states that when you change the oil you should use liquid gasket on the sump drain plug?
now what dose everyone use for this as the threebond stuff is dam expensive.

car info

1997 2.0ltr auto impreza awd.

many thanks in advance RCT

 

No, no need for any gasket other than the standard sealing washer. Best practice is to fit a new one each oil change, but IME even that is far from necessary, never seen a re-used one leak.

 

That's news to me

You normally just use a copper crush washer over the sump plug (ring of metal designed to flatten and be oil-tight when sump plug is torqued up correctly).

 

many thanks to you both will do as normal then.

I sometimes use a little ptfe tape dependand on the car and type of plug. But have never heard of threebond being used on a sump plug.

As above a new crush washer is all that is needed although the exisiting one would probably be ok
