Why does buying a 6 pack cost $55 but buying 1 for $7.50 six times cost $45?

Because the single one is high mileage, not advanced synthetic.

is this oil suitable for gasoline engines with 200.000 km milage?

I'm sure it is. I have a 2004 Toyota Corolla with 100,000 miles on it. I have used various brands of fully synthetic oil in it from day 1. The car doesn't look as good as new, but the engine seems to still be performing like new.

I am seeing castrol edge 10w30 black quart and 10w30 gold quart with titanium. The gold quart is cheaper than the black. Which is better?

The 10w30 gold quart is extended performance. It should last longer in your engine before you need to change it.
