Red_Bean_Bun;1056803 said:One assumption gaskets and seals fails is overheating. Sometime this may be due to EO shearing and deteriorating. This applies to thicker oils as well though it maybe more resilient to thinning.
But there is a price to pay for using too thick of an EO as it makes the engine work harder.
A suitable OCI coupled with the right EO should provide some level of longetivity for the gaskets.
Pre-detonation and misfiring can also contribute to gasket failures ......

N52 is designed to run on 5-30.christopher ngo;1080879 said:I even put 5W50 in my e60 last time.
I can feel engine noise much lower but. . . . . . someone told me fc suffer. For me no issue as my mileage less than 200km per month.
