1.6l GDI gamma engine, used quaker state, Valvoline, Pennzoil, whatever oil every 5k. It doesn't really matter what oil you use for the most part, especially in modern TGDI/GDI or even MPFI low tension piston ring engines, soot, combustion blow-by, and fuel are bad for your engine, and they make even nastier chemicals when exposed to the extreme heat many modern engines run at, most modern engines run as hot as the material science allows in the name of efficiency.
I find it hard to believe that a modern synthetic oil with multiple manufacturer approvals that is good for duty in 500 horsepower V8s with twin turbos, on an autobahn, in the summer — will break down in a 1.6 liter shooter after 5k miles, leaving varnish all over.
