I've had a B6 from new last October, and have covered just under 9,000
miles, but I can no longer [1] adjust the chain to keep it
appropriately tensioned.

Regardless of whether I adjust the chain as per manual recommendations
(using the swing arm marks), measuring rule or straight edge, the
tension of the chain varies when I rotate the back wheel. It looks as
though the chain does not sit uniformly on the sprockets throughout
it's entire length, instead sitting someway up the teeth around the
bottom of the sprocket causing the tension to become too tight.

All the teeth of the sprocket look good, there is no 'hooking' and all
the chain links move freely.

You also hear a slight brushing sound, the frequency of which varies
with speed, when the bike is in motion.

As best as I can tell the wheel is in alignment.

Is this a case of the chain becoming unevenly stretched?

I lubed the chain regularly [2], but summise that this is probably not
sufficient. If I have to shell out for a new chain, would a Scottoiler
help prolong it's life? What is a reasonable life of a chain anyway?

If it's of any consequence, most trips are between 50 and 80 miles;
not a lot of short runs.

[1] Perhaps proof that I never could!
[2] Minimum of monthly, but more in the wet.

Yes.

Replace.

Can you fit the number plate kit? Holds the larger touring reservoir.

It's a good idea as a last resort and one I hadn't thought of, thanks.
That's another £32.00 though and the number plate arrangement is already a
bit ugly imo. One place I'd thought of was on the rear hugger next to the
chain guard. Will require drilling a couple of small holes to take the cable
ties but it'll be out of the way and easy to route the pipe work. Hope the
weather holds off for Saturday
