This might be a question that you guys have covered many times, but I'm looking for any input from personal experience that your engine is running fine.
My engine calls for 10W60 oil (2004 BMW E46 M3 engine)and it seems a bit sludged up for internal parts (dark stain seen from oil fill hole). If I'm "NOT" looking to do AutoRX nor engine flushing chemicals. But I'm looking to run some very light 5W20 or even 0W20 synthetic oil at idle for half an hour. Am I pushing the tolerence of the engine with low oil pressure and high engine temp?
I don't wanna blow up the engine just because of a light weight oil cleaning method.
Thanks for any input !
