Wasn't getting notified of recent responses, sorry!
Yes I was considering trying the VR1 20w50. Either that or Mobil 15w50, comes down to whatever is a better deal at the time of change, only plan on running either in the warmer months.
I am currently running the Valvoline euro 5w40, consumption is none so far albeit on a small sample size (600mi).
I am skeptical of my own oil temp reading, this was taken through a scan tool and like a I said it was a cold day with no hot lapping. I will try the temp gun next time I am out! Would be good to see what temp the manual gearbox gets to as well...
