I use one of the Oil Bowls with drainer tube you can purchase cheaply from motor factors.
Then just pour the oil back in containers for disposal.
The Diesel seems to give most oil back if run first and then left to drain, very little kept in oil filter,
presume similar on the petrol models?

I still love this marque and I will still be around, preferred selling to breaking, as a great runner and performer"
