I use Comma fully synthetic 5-40 which is probably a bit of overkill but I only use it because that's what I put in my other car which has a rover K series.
I generally use the full rev range (AKA rag it) when driving my cars and only change the oil every 6000 miles so I figure the fully synthetic is a bit of an insurance policy.
The thing to watch is not to go back from synthetic to mineral without flushing the engine as i believe that can cause issues.
I use Castrol Magnatec (sp?) - expensive, but worth it .. and I aim to change engine-oil every 3months, and use boring Halfords 80/90 Oil for Axles, and Gearbox, and aim to change the 80/90 every 6months!
