G-Oil synthetic 5W30: 1 quart
Also, Pennzoil Ultra 0W20: half quart... perhaps for topping off. Does this sound alright, or do I need to add anything?
Try to mix beer, wine, rum and tekilla on your next party. Just because of you have them in a bar. I don't want to be in your shoes next morning...
Main question: what for?
Very poor example when compared to what the OP asked. He's not mixing different fluids together for a juicy cocktail, he's mxing the same type of fluid with different flavors. Like mxing several different beers together or several wines together.
I've also been mixing oils for many years (usually just the OP, add a half quart or so of leftover oil B to 4 quarts of oil A. Haven't had any engine failure either. Still going strong.
