Just read that Penz has decided to change the additive package in LL 15W-40.... Moly and Boron are now gone....Since Penz is owned by Shell they may just be repackaging Shell's own Rotella brand ?? Dont know if thats the case or not but is possible... So just a heads up that their new LL 15W-40 is not going to be the same as the stuff you have been useing.

WHAT NO BORON! j/k Thnx Al, I wonder if I would have noticed the lighter color. Wonder if current on-the-shelf supplies at WalMart are still the old formulation. Just used my last jug. THNX!

See if you can find a big jug of "URSA", over-the-road big truck diesel motor oil and check if it is still formulated the old-fashioned way??

Try a "BIG", interstate island Truck-Stop???

Pdq, I just liked that particular formulation of Pennzoil. I still can add a smidge of EOS, which likely has all the zinc and boron the mill needs!
