Quaker State???? Any good?

QSUP is amazing and the biggest steal in quality for everyday price going

Saw a few reports recently from people with NON-oil burning Theta II's who ran QSUP or QSUD (one switched to Euro oils but had a lot of miles on QSUD). Keeping one of those Theta engines from burning is about the best endorsement I can think of for an oil.

Quaker State Euro was well liked on a German car forum I used to peruse.
