It's basically the idea that once you've spent money on something, your current and future decisions need to be made in light of the current situation, and not in some sort of quixotic effort to "make the investment pay off". The whole idea is trying to avoid letting "sunk costs", i.e. those...

So? Vertical integration isn't some kind of magic bullet. It's usually a cost thing where you own your suppliers and your distribution channel(s) to control costs. But there's also a pretty compelling argument for letting specialists do their thing, and just buying their products, rather...

I did mine a couple of weeks ago. I replaced the Honda OEM with a Purolator Tech. They seemed about the same, and neither seems to be particularly restrictive or fine filtering. I get the impression that they're really just supposed to keep your evaporator coils clean and filter out the big...

Sounds like you need to talk to a probate lawyer.

Most likely all oils are that cheap, and they're just pricing them where they believe the market will bear. Now why they're choosing to price that oil there, I don't know. The retail price of something and its cost to produce/ship don't have any actual relationship to each other, except that...

Wow. You really aren't getting this. If you make a claim that any specific anything is different from the rest, the burden of proof is on you to prove it. Just because nobody else can disprove your claim doesn't make it true. In this case, you're claiming some oils are better than...

No.... If you're claiming that one oil that meets the same specs as the rest is better than they are, then the burden of proof lies on YOU. Just because we can't prove that your oil isn't better doesn't make it actually true. That burden of proof lies on you to show it to be so. It's...

I'd guarantee there are indeed scientific studies about parachutes and equations that apply to the amount of weight, size of the canopy, and the altitude. The Air Force doesn't f-around like that; I'm sure they have solid science backing up what parachutes and how many they put on the stuff...

Oh yeah. The hate tends to be because many of their products make claims without actually officially being labeled as meeting the specs and were sold through a multi level marketing scheme like Amway or Mary Kay. Those two things made it instantly suspicious to many people.

Maybe, but how do you measure that? It's all anecdotes unless you can show the data behind what you are claiming.

That's more a consequence of design or manufacturing flaws than anything else. If you have one of those engines, it probably doesn't matter much what you run, because it isn't going to overcome the design/manufacturing flaws, just as you point out. And if you don't have one of those engines...

Shy of having inside information, there's no way to really know what that indicator shows. Even if there's a dielectric sensor, who's to say that's not just a parameter in some oil health equation that includes hours, average temperature, average RPM, number of cold starts, or whatever else...

Basically what happens is that a lot of parts end up reaching their effective lifespans due to degradation due to time related issues (uv, ozone, heat, etc.) or other parts start to wear out, and meanwhile the engine is running fine. Modern engines last a really long time even with...

Fair enough. What do you think he'd have thought of 5w-20 or 0w-20?

What part was he skeptical about, the 10w part or the 30 part?
