Having read the post/thread Spike/Mike have commented on, it does appear the G070 from VW has the edge on viscosity. Hope it is not to dear for all this cold weather motoring, otherwise, I will have to wait until the weather warms up to at least 30 degrees before starting up my A2. This could be a long wait. Hope the weather proves me wrong. Go on, only for this bank holiday weekend.
Thanks to all for the info, as usual..Excellent and well supported with facts.
