Nice find on the SL rate 10w30! Wish I could find that around here.
G, it's my understanding that the 10W-30 High Mileage M1 is the only one that is SL rated that still may be on the shelves. NAPA Fleet is another that you might have luck with. The OLD I stress OLD Castrol GTX Diesel is another. A few months back this same store had a few pallets and now its completely gone.
So, unless you wanna add ZDDP to your SM, SN rated oils.... thats the last hope for the older stuff. I even checked the CAT dealer and they have gone to the newer stuff as well. So, it seems there are very few that still have the higher amount of Zinc levels we need.
Just remember not to go crazy on the zinc.. It can hurt our 2F's over time if too much is introduced to them.
