Hi All,

My RX-8 has +44K miles on it. I need to get more oil, and one shop said I should be using 5-30 after 25K miles.

Then I found numerous articles on engine failure due to using the 5-20 oil after various types of mileage.
Question: Should I put 5-30 in it, since it seems to run fine? Now I'm worried that my engine might fail if I don't switch.

Any comments are welcome.
Thanks
Bob S.

I'm using 5w30. It's fine.
Also, it's the wrong forum section to post this in.
