Not exactly. It doesn’t have to be that costly.
That same oil is $8.30 per quart with the Amsoil Preferred Customer membership. Or a less costly alternative could be Synthetic SAE 10W-30/SAE 30 Heavy-Duty Motor Oil (ACD) . The ACD works out to $5.97 per quart Preferred Customer cost.
ACD 10W-30:
Zinc content 1339ppm Phosphorus content 1180ppm
Around the 1200ppm mark for Zinc and Phos., is considered to be adequate for flat-tappets.
Also, consider the cost of a quality alternative motor oil plus the cost of an aftermarket additive. The two added together is getting up there in price. In the end what’s the difference in price, $10-$12? And if you go that rout, you’re not guaranteed 100% compatibility of the motor oil additive package to the aftermarket additive. For example are you going to end up with oil foaming tendencies by using a motor oil and aftermarket additive? That's happened.
One oil product, one cost, no worries… Some like to go that rout, but not all. CompSyn

Stock or mild builds with flat tappet cams like at least 1200 ppm zinc. Major builds more, due to stronger valve springs etc.
I run 5W40 Shell Rotella T full synthetic which has close to 1400 ppm zinc. Most, if not all, heavy duty (diesel) motor oils have a good amount of zinc. Racing oils too, but may not be suitable for every day cruising. www.bobistheoilguy.com has tons of info.
I read on Bob Is The Oil Guy's web site a used oil analysis stating that the new CJ4 Shell Rotella T (SRT) 5W40 full synthetic at about 1380 ppm zinc. Last night I emailed Shell's tech, who responded back that their newest CJ4 SRT 5W40 has 1200 ppm zinc.

Chevron Delo 30wt has ~1200ppm zinc according to their datasheet for it. Here it costs me $13/gallon.
If you ever find yourself in a fair fight, your tactics suck.

I totally agree with the comments about buyer beware. Back when all the SM oils came out, I contacted many of the oil mfgs and was told SM was fine for flat tappet engines. Now we now better. Even after the issues came up, when I contacted Amsoil, they wouldn't tell me how much zinc was in their oil, but it was enough. I had two pushrod failures on Amsoil diesel oil back then, change oil to another brand and no more problems. I like to run the motorcycle oils, as they have all the additives you need, without the extra stuff in diesel oils that you don't need. I like this in 5W40 for drivers and our motorhome and in the 20W50 for the TT340 Chally. http://www.castrol.com/castrol/sectiongenericarticle.do?categoryId=9021703&contentId=7040544

Just found a bottle of Lucus additive at Advance for $12. It has zink and some other stuff in it "specially formulated for engines using flat tappet cams" It's a break in lube + additive.
Is it Lucas Oil Stabilizer or another product. Just curious. Below is some information on Lucas Oil Stabilizer.

They have two different products. One is an oil stabilizer/smoke reducer similar to 'motor honey'/stp, etc. The other is a zddp additive and motor/cam break-in product. It comes in a 16oz bottle and states that it is not to be used in 1994 or newer cars as it will trash the convertors. I used a bottle to break-in my recent 440 bullet in my sig car and just picked up another for an oil change.
