Why risk your engine's health over 6 bucks? My 2 cents.
How does ur engine suffer from less than a quart of non similar oil?.. wont make any difference. I dont think the car is able to figure out the difference.
Doubt it will do anything. However, I stopped mixing oils years ago after VVT, Fuel Management, DI, Turbos, etc. starting becoming the normal. It's not the days of the old 318's and 350's my dad and I used work on when I was a younger. I don't put anything in the crack case that isn't in the manual.
Y'all do what you want. Mix away. But, I'm not stressing over wasting a quart of oil.
