Not worth the money. I use Valvoline 10W30 every 3000 miles and when I opened up my engine at 62000 hard miles it looks like a new engine. I don't think it matters what kind you use if you keep it clean. I work with a guy that got 430,000 out of a Geo Metro and he used Valvoline. He just changed his oil every 3000.
