Would appreciate opinions on this topic. I have a 1999 Acura 3.2 TL with 85,000 miles. The oil originally specified by Honda was SJ 5w/30.
It has has a steady diet of Mobil 1 5w/30 since new, progressing from SJ to SL and SM. It runs great and neither burns nor leaks oil.
With SN now appearing, I'm wondering if I should switch to Mobil 1 high mileage, which is SL rated. I don't think it necessarily needs HM's extra cleaning power and seal conditioners, but wonder if SN's further reduction in things like ZDDP would make sticking to SL a safer bet.
The real answer, I suppose is that it doesn't really matter, but that's why we're here, right?
Incidentally, on Mobil's check mark comparison on the bottle, HM gets an extra check compared to "normal" SN Mobil 1 for high temperature protection. Curious, isn't it?
Thanks for your thoughts.
