You know I was thinking that too, whilst reading your comments ...
Hi @dag019, I am amazed no one mentioned using Castor oil.
A further option to my previous post is to look at "Super Tractor Universal" which is fine for turbo engines. A couple of well known makers are Smith Allan and Exol, available for under £70 for 20lt.
Suto is what I use for the tractors and my 300tdi

Last week I changed my focus 1800tdci's oil, had an issue with the sump plug in that its sealing washer was fubar and threads not great. To keep car on road fitted a Dowty washer and filled with fresh oil then ordered a new plug/washer.
This morning I drained the oil again to fit new plug and was supprised as to how black it already was after only about 150miles. Comments?

Could it be that the engine has galleries that don’t fully drain so there’s old black oil remaining ?

Yep that is probably it.
Dry fill and wet fill, find out the differenceand that is how much old oil is left in the engine after you have drained it.
Literally just jinished oil change on an mx13, ran for five minutes and oil is black.
or maybe oil is just sticky
