FWIW:
1) Phillips Shield and Kendall are both owned by Phillips Petroleum
2) Penzoil and Quaker State are both owned by Royal Dutch Shell
3) Castol is owned by BP (British Petroleum)

So.. Pick the one you like, that your friend likes, that your Dad used.. or just the on that's on sale.. Just make sure it meets the manufacturers specificationsBlackstone labs .... The answer is... they're all interchangeable so long as they meet the oil weight and certifications for your vehicle. Mobil 1, Pennzoil, Valvoline, even the discounted brands such as Walmart's Supertech and Peak will not wear your engine out any quicker than any other brand that meets the basic standards for your vehicle.
