What do you guys think would be better for a '01 530i?
LC20 or Auto-RX?
Engine has 80k miles on it and probably had some dino oil changes that stayed in for a little too long. Now it's running GC and seems to like it. But the last batch of GC brought out some valvetrain tick similar to running M1 0W40.
I think she's past due for a cleaning...
I know if I use ARX with GC that I should extend the OCI for the cleaning phase.
But do I have to run a dino oil for the rinse phase?
Or again, if I use synthetic just run a longer OCI as compared to a dino oil?
Would it be better to use BMW 5W30 oil?
I've read that it's Grp III, but I'm not certain.
I'd prefer to use a xW40 since it's summer.
Has anyone run 10W40 dino oil in a newer BMW engine?
I suppose something with a low sulfated ash % would work well?
How does LC20 compare to Auto-RX?
Does using synthetic oil affect it's cleaning ability?
Cleans better or worse than ARX?
Does it condition the seals like ARX?
TIA
