I use QSUD 5w30 in my Yaris, mostly because a local home improvement chain, Menards, will run a sale concurrently with a manufacturer's rebate every few months, ends up being around $3/qt or less. I believe Menards has some deal with QS, since one of the Menards drives the QS car. Meets all the highest manufacturer's specs, has good VOAs and UOAs.
