It does have validity, but I think it is increasingly evident that being approved for Dexos is not a “difficult” task. With SN+/SP, it seems like many synthetic blends and house brand synthetic oils have no issues meeting the performance requirements.So you don't believe that standards like Dexos have any validity ?

I think this becomes a discussion of buying an adequate oil for the application vs buying one that is overbuilt. Any oil that is approved for the spec should be adequate. Buying a product that is overbuilt carries some advantages, such as: 1) having an extra margin of error when you do not change the oil on time, 2) having operating conditions are that are outside of the anticipated customer use parameters. Of course, I would expect that an oil that far exceed specs may keep an engine slightly cleaner as well, but it is difficult to confirm that this benefit can be directly correlated to improved engine life.So what is that validity and just exactly how many more 100's of thousands of engine life will it guarantee me?
I agree and I’ve deleted most, if not all, of the completely false posts.Admittedly I'm no expert....but man. Some of the info I'm reading on this thread is completely counter to much of what I've learned over the last couple of years on this site. Sounds like some antiqued nonsense someone's grandfather would say
Solid choice esp if someone doesn’t want to deal with an online rebate. Prob in my top 3 choices. A few days ago i purchased some M1 EP HM 0w20 on rollback for 24 minus 12 rebate = good deal.Even QSUD 5w30 is $15 at Walmart right now, don’t see any reason to not run synthetics
How about "modern oils are just really, really good" ?It does have validity, but I think it is increasingly evident that being approved for Dexos is not a “difficult” task.

Sure, that is one way to look at it.How about "modern oils are just really, really good" ?
My understanding is synthetic oil is better than conventional oil in every way, especially at extreme temperatures.
Switching to synthetic is not going to hurt an engine.
Yes....I noticed some things were missing since I visited earlierI agree and I’ve deleted most, if not all, of the completely false posts.
define "better" and I can assure you its not "better in every way".
Like what ?Seems like we have more oil-related issues than ever before nowadays though
Considering the tiny number of people who actually run those 15-25k miles like Mobil or Amsoil say they can do, yeah, they have little benefit to customers. People buy/use these oils and still change them out every 3000, 5000, 7500 miles and in those cases, they are wasting their money when they pay extra. Heck, even Amsoil attempts to justify their outlandish price by pushing for longer change intervals. If people did run them 15k, 20k, 25k miles, then Amsoil makes sense from a cost perspective.are you suggesting that premium oils such as Mobil 1 EP, Amsoil, etc are unnecessary and offer no benefit?
Oil consumption from piston ring deposits and timing chain wear from extended oil changes.Like what ?
I was referring to more uniform molecular structure, which offers better lubrication.define "better" and I can assure you its not "better in every way".
