Oil Help

[Kenna802]

hi there just had a motor rebuild about 1300 kays ago, ( motor was babied for that time untill 1100 kays than put in on run in tune) I was running synx by gw and had no probs but now i have upgraded to motul turbolite and the car blows blue smoke on cold starts untill warmed up??????????? my mechanic said that it could be due to the different detergents used in the oils etc and suggests that i go back using syn x for the time being. Has anyone ever come across this situation? and if so what was your course of action?
