It's true that synthetics will hold up longer if the engine oil is extra hot and that's why these performance cars come from the factory filled with synthetic. But on it's website, Shell admits this potential benefit is irrevalent to most engines because the oil doesn't ever get hot enough to badly oxidize conventional oil.
If you spent days searching all the tens of thousands of posts to the Tundrasolutions forum over the years you'd not likely find even one where an owner reported excessive engine wear, damage or failure that resulted from the use of conventional oil. Instead, you'd find hundreds of posts about engine damage or failure caused by abusive driving habits or delayed, neglected or improper preventive maintenance to the engines systems; i.e. lubrication system, cooling system, ignition system, fuel system, emission system and exhaust system.
