take a look at the viscosities of mobil 1 5w30 and 10w30 shown on a UOA..

i have a taken a look at a number of UOA of those oils coming out of a wrx and other motors and the oils have sheared down to a 20 weight.

if you track your car or drive it hard in general (or if you have a turbo) i really think you should think twice about weather 5w30 or 10w30 that is effectively a 20 weight oil is good enough to use

and for what its worth.. the whole reason i get these UOAs to make sure that the oil is actually fine for the engine and my usage.. not just because the motor 'sounds' different or 'feels' different

for all the debate around oils in most car forums i'm surprised there aren't a lot of UOAs being done.. it is well worth it to bring some tech to the table when it comes to this stuff...
