Any engine oil that has a commercial that describes some fancy technology "liquid titanium technology" (Castrol Edge) is pure marketing garbage. Synthetic blends are also terrible because even if it's 50% synthetic, the 50% non-synthetic oil won't fit in the places the full synthetic oil does. It's basically a filler and the synthetic oil breaks down quicker because there's less of it in the engine.

Leave the non-synthetic and blends to the Priuses. A high performance car needs to be full synthetic especially if you race with it. It might cost more but you won't have to change it as often. A blend, you gotta change it like you would conventional.
