Excellent post. That is one reason why I buy Chevron. They make base oil and additives in-house, so I am getting the best chemistry for the money. Check out the Chevron Oronite website for lots of information about additive packages. I can just buy base oil and additives, blend and bottle, and call it "Jimzoil".
Car & Driver interviewed a chemist for a oil company. He said that he custom mixes blends for each of his cars and blends some custom mixes for his neighbors too.

Now you are talking specialty oils, specially blended for a specific purpose. Your right, cheap "generic" oils do not have these additives, but neither do the brand names, dino or syn. Buying Castrol GTX or Mobil1 does not get you these additives either. So unless you need them, paying a premium for a brand name oil just to get extra additives that you really don't need still doesn't make sense.
Actually, diesel-rated oil, CH-4 or higher, has higher detergents, anti-foam and more ZDDP than SL-rated gasser oil. I can still buy it for less that $1/qt. No friction modifiers either, so it does not thin out at higher temps.
So if you want to spend more money to get more additives, buy a generic 15w-40 diesel oil instead of a brand name 10w-30 gasser oil.
I have confidence that the name brands will deliver the protection and engine life expected of them. I do not have this confidence in oil that costs less than a bottle of coke from a vending machine. Just because brand x meets the API requirements does not mean that it performs equal to API brand Y.

Hmmm, now you've got me thinking, Jim...
But can you do that? Just throw some base oil in a pot, dump in an additive package, stir it up with a stick, and then it's ready to go into the crankcase?
The Group 3's can't stand the thought that someone else MIGHT have a better oil in their engine and are thinking of blending their own!
Meanwhile the Group 4's are loosing sleep thinking of a way to save an extra 10 cents per quart, while preaching it's all the same except for the label.
A shrink would have a field day around here!
They trust Ford Motor Company enough to give them $30,000 for a truck but not enough to give them $1.80 for a quart of oil.

Price is what the market dictates. If putting a brand name oil in your engine lets you sleep at night, then it is money well-spent.
As far as performance goes, you can say the same for gas. Without a doubt, 93 octane premium gas is "better" than 87 octane regular gas. But so what? Most engine computers can't tell the difference. So why pay for performance that you don't use?
And BTW, that extra $0.20 you pay at the pump is probably only $0.05 wholesale, so your local corner gas station gets a 400% markup.

It’s not so much about price as it is about knowing what I’m buying. Chevron delivers great wear numbers at 1.10 a quart so why should I take a chance with the unknown or bare minimum.

So does ST at $0.84/qt.

I'm one happy guy! Here are my Blackstone results which came in today.
CHRIS: No problems showed up in the initial sample from your Power Stroke. All wear read at or below averages for this type of engine, which is a very good indication of normal wearing parts and careful operation. The universal averages show normal wear after almost 5,000 miles on the oil.
Insolubles (oil oxidation and soot due to heat, use and blow-by) were low, showing good oil filtration. No fuel dilution or anti-freeze was found. At 30,000 total miles, this engine appears to be doing very well. Try 8,000 miles on the next oil. Everything should still look good.
Looks like I'll stick to my Frams and Walmart oil.
I’m going to have to end my argument here because I don’t have any numbers to toss back at you. I still hold firm that buying a brand name let you know what you are getting and you are getting more than the minimum protection.
