I found several cases of SL oil.Valvaline , Castrol , Delo 400 and Rotella.From what I can tell the SL classification ran out in 2004. Is this before they reduced the levels of Zinc.The Valvaline bottles have 2001 trademark on the labels.The others have 03 and 04 marks.I bought the Rotella all 11 qts.It had light blue labels.I need to know if I should go back and get the rest.Thanks for any answers Chad.

What's the first API service classification listed on the Delo and Rotella? Should be either CJ-4 or CI-4; whatever service classifications are listed AFTER the first one aren't important - only the first one matters.
"SL" oils have 750-950ppm of phosphorus, and "SM" oils have 600-800; CJ-4 was around 1400, CI-4 is around 1200.
