If you're going to upgrade to a synthetic oil why would you not choose the superior 5w30 grade?
Honda specified a conventional 10w30 for the S2000 back in the day.
No manufacturer has ever specified a synthetic 10w30 as it is a redundant.


Yeah I know this is a somewhat heavily debated topic. I've read both sides and I still think there might be something to why Honda didn't alter the specifications even though the S2 was produced until 2009. It could just be they didn't care or were lazy, but they switched the Honda Fit from 5w20 to 0w20 mid-run, so who knows. Besides, I only put about 1000 miles a year on the car, so it doesn't really matter what I run in there. Switched from M1 just to try something new, and I think the M1 was burning slightly (common on AP1s).

Yours (and this might be different for 5w30) looks like the older version, so I'd be curious to know what the manufacturing date is. You can differentiate the labels on the bottom lefthand corner, A vs B. The "A" version I found was manufactured back in 2011, and the "B" was mid 2012 onwards. Talk about nitpicking..

What's the manufacturing date on your bottles?


This is embarrassing: The 'New & Improved' 60% better Castrol is from July, 2011, and bottled in Plant A.

I have no idea how I missed that. It is strange that Castrol decided to roll back the claim a year later...



Yep have to watch out for new old stock, seems to be mixed in.
