I too am running 5W40, but from Duckhams as the other stuff wasn't
available. A lot of leaks sprang up. I had the sump gasket repaired
and also the turbo oil lines repaired at the same time. The synthetic
has a heck of a cleaning action and some bolt up the front of the
engine hadn't been seated properly and it took the mechanics forever
to find it once the synthetic cleaned out the muck that was keeping
it shut. I never saw the bolt, but they say it was somewhere under
the timing belt cover and wasn't seated properly. Trusting them they've
probably gone and siliconed the thing shut, you should see what my
sump looks like. :)

The 5W40 runs well. When I start up in the morning I don't wait
for it to warm up, I just do as the book says and drive off. At
startup there is major scratch from the engine, but I'm attributing
that to oil having drained off parts. The only problem with the
5W40 is  that my oil pressure is lower. At idle I'm way below the
1.8 bar figure, sometimes just dipping below 1.0 bar. When running
I usually don't see anything over 3.5 bar, but at cold it is
obviously higher.
