Hi,following on from recent posts can anyone tell me what real differences in flow rate between a 10/40 A3 oil and a 5/30 A3 oil at 0 centigrade and at -5 centigrade and even down to-10 centigrade please? Thanks in advance

Hi Pablo, i suppose what i am trying to get at is the difference in time to get oil to the valve gear at those different temps with oils being say the same semi synthetic spec the only difference being a 10/40 versus a 5/30 viscosity, i suspect it is not a really huge difference in real world conditions, thanks
