More zinc provides “longer” wear protection, NOT “more” wear protection. So, if someone tells you that you must have a high level of zinc for sufficient wear protection, no matter who they are, or no matter what Company they may represent, DO NOT believe it. Because they are proving that they DO NOT understand how zinc really works, and are only repeating the same old wives’ tale with absolutely NOTHING to back it up.
I’ve also “wear tested” a handful of used oils, both synthetic and conventional, that had 5,000 miles on them. And in every case, there was NO REDUCTION what so ever, in wear protection capability, even though the zinc levels had dropped by around 25% on average. So, this is even further proof that the zinc level is not tied to a motor oil’s wear protection capability.
Why should I believe the guy telling me not to believe anyone?
