It's also old, and probably not the same stuff that's available now.
If indeed it really is an SL. The new clear bottle 10W-30 synthetic says API SERVICE SM/CF on the top line, then the next line starts with SL. It would be easy to miss where it says SM.

If you read through my
thread i posted(with pic)weeks ago you'll see it's not old but new bottle new stock 2009,and yes it is SL only.
SL is SL VOA would be the same...
Ah yes, I did see those pics.
Just because it's SL doesn't mean it's going to be the same additive levels in the VOA.
All 10W-40 being SL would be fine in this day and age, because I can't think of any manufacturers that call for it, so it would be used only in older vehicles.
