I've been running ST dino(both WPP and XOM versions)in my vehicles for many years without problems and have had good UOA's. It's a decent oil at what used-to-be a decent price. The 5 qt jugs I have in my stash were from the $4.97/jug days. If I were to buy oil now though, I'd either get Mobil Clean 5000, Pennzoil Yellow bottle, or QS green bottle simply because it's only a few cents more.
