Bit confused. Getting ready bring car for mapping. planing change oil. And hearing different opinions.
Car has 11mm oil pump
Now running in car millers xf longlife eco 5w30. Oil pressure at idle 850rpm when hot around 2.3bar
Some people advise go bit for heavier oil like 5w40. Had this earlier in car oil pressure was around 2.7bar when hot
Some others saying go for very heavy oil like 10w50 or 15w50. But my pressure would very high.
What oil weight to go for mapping?
PS.my idle speed is 850rpm far as I know factory set idle is 600rpm
