In other words, there is a noticeable difference in fuel economy driving around town before and directly after a long trip.
Could this be related to a VIS motor problem? Are there any other symptoms with VIS motor failure?

Don't want to worry you but the chances are that one, or both will have packed in. Failure rate is at approx 85%, at the last Midlands meet I tested cars all of which had at least one failed, most both.
(even one that was 4 months old)
Oil ingress unsecured components, and sticking vis butterflies all cause failure.
When I got my V6 both mine were shot and you couldn't really tell that much or when they fail you just get used to it. You will certainly tell the diference when repaired.
If you don't use high revs then the power vis isn't quite as important as the balance one which operates at lower revs and will have an effect on fuel your consumption.
Don't worry too much your car won't come to any harm it just won't be at optimum.
If you can get hold of the vis tester or alternatively get to one of the meets then we can test them for you and may be able to see about repairing them for you.
