Except for the Amsoil XL Line, Amsoil's other oil's are extended drain oil's.
Amsoil 100% Synthetic Oil is probably a great oil under the right conditions. Lets say you buy a brand new car, and you are only going to keep it for 5 years or 100,000 miles, and then you will be trading it in. In this scenario, Amsoil is a fine oil. The other scenario is if you are doing alot of long trip driving, say about 50 to 100 miles a day, go ahead and do an extended drain and more than likely everything will be fine.
If you are doing short trip driving, then I see that Amsoil would not be the best choice.
If you are keeping your car for maybe 200,000 or maybe even 300,000 miles, I would think that an oil like Pennzoil Ultra that has alot of cleaning properties would be the better choice.
Your engine will get dirty over many miles and years, my gut feeling is that the Amsoil 100% Synthetic probably has more anti-wear additives than it does cleaning additives.
Is Amsoil going to meet the new GF-5 Standard, seems like the new standard is going towards more cleanliness. We all know that engines do get dirty, just take a look at the threads in the Oil Additive Section.
In the short run, have fun with Amsoil, but if you are keeping your car for the long haul then you might want to look at Pennzoil Ultra.
One last thought, it is easier to keep an engine clean as opposed to trying to clean it up.
So according to your post, Ultra has LESS anti-wear additives but is LOADED with cleaning agents.
So at the end of the day, your engine will be EXTREMELY clean but completely worn out.
Sounds like B.S. to me, to be honest with you.
The way i see it, Amsoil has the same amount of cleaning agents as Ultra but is also loaded with additives that help it run much longer, hence why it costs more.
I do agree that some oils are loaded with more cleaning additives then other but at proper OCIs any El Cheapo dino oil will keep your engine spotless.
I agree mostly here with you Artem...but really if any oil PREVENTS your engine from getting dirty "WHY"?!, do people obsess with needing an oil that focuses on cleaning up the engine?
I personally don't use Amsoil for cleanup intervals, that is a waste, it's best used(IMO) in extended drain service.
I use other oils, like one of Pennzoil, or an HDEO, with perhaps an oil additive that is reputable for less than 5K(which in severe service is all a conventional is GREAT for, let along capable of perhaps give or take 1-2K more)...yet with a full synthetic like PP or PU in servere service in a dirty engine needing cleaning, they shouldn't be kept in for 10,000 miles at a time if needed for cleanup. Regardless of how clean it can help the 'dirty' engine become, if can't keep the gunk in suspension for extended service you are back to where you started.
I don't believe the OP has issues with needing cleaning, and if so, could benefit from another oil. In the best scenario, any synthetic could make it 10,000 miles without problems arising. The question is, what does the OP want the oil to do time wise? If he has settled on 10K, he could try another oil and work up to 10,000 but I'd do a shorter interval(5-7.5K) on my first interval with the whatever other oil the OP wants to try instead of Amsoil.
Yet, if it's extended interval service the OP wants, and isn't pushing past 10K...he has to pay for one of the best oils at that(Amsoil) unless it's just an engine/application that is super easy on oil and any syn can make it. Back to square one, having gone full circle, he still would have to see how any oil holds up to 10K before just blindly hoping it's working as well as Amsoil.
