Since many other stores only want to stock the T5 in 15w40 now, any ideas if Shell might discontinue the 10w30? What I bought yesterday was recent production, but i have no idea when they announced the 15w40 T5.
Here's what I saw at the local TSC:

Still glad I went to TSC, found out my son really likes the store, and they have the 2.5 gals of T-15w40 which I run in the BMWs. I think I might pay a few $ more over WM just to get the big bottles - they will be useful as waste oil containers, or to save the old oil from an upcoming ATF flush I am planning until I'm satisfied that new ATF doesn't cause problems.
I hope they are not going to roll it back...I have a hard enough time finding a 10w30 (state contract availability issue) so the more 10w30 out there, the better.
As far as why T5 went 15-40... sales is my guess. I bet the average diesel buyer is the "thicker is better crowd" so it just did not sell well. Some of the 10w40 jugs were extremely dusty when I cleaned them out.
