You can find Mobil 1 TDT and VR1 at most retail auto parts stores (at least in Baltimore). I've been very successful finding TDT at Walmart also. [snip]
FWIW, my local NAPA is running a $4.99/qt sale on Mobil 1 Oils (I think through June). That included the TDT last time I bought.
IIRC, last time I saw it at Walmart it was closer to $25/gal.
