I am watching this thread with interest. I have used a lot of ST before but now that Warren has been sold and it looks like there are questions about the two different ST Synthetics I looked at different options. I have oil changes to do this weekend on both my own and my wife's Nissan Rogue. I will not have time to get to WM in person so I ordered oil and filters online last night to be delivered to my house tomorrow. ST regular 0W20 was $17.98, Valvoline Advanced 0W20 was $22.47. With the $5.00 per jug rebate Valvoline is right around the same price as ST but even without the rebate its only a few bucks more for name brand Valvoline so it makes sense.
I don't know what is going on with ST. I saw a couple threads where people were questioning the difference between the regular ST and Advanced ST, some say there is no difference in add packs and it may just be a marketing trick. I like the white ST Champ oil filters but they have not had the ST6607 in stock at my WM for weeks now. I wonder what is really going on and if we might soon see a new supplier for our beloved ST. For now it's back to Valvoline and Fram for me.
