I have a FIAT 1.4L turbo 6spd that calls for 5w40 I've used premium brands and store brands 5w40 and when i do the UOA it always shears down to more a 5w30. Im worried about long term wear since the oils keep shearing down.
My question is would using a 5w50 help stop this? (Logically wouldn't it shear to a w40?) Appreciate the info
