Mobil 1 vs Amsoil

[Trick Pony]

What is the difference between the two oils? If both are fully synthetic, then why is Amsoil so much better? I'm putting this in my new mustang and my stang will be sitting more then driven so I'll probably get to the months before the mileage when it comes to when the oil has to be change. So I want really good oil in my engine.

Over time, oils break down and oxidize. This causes it to loose it's rated viscosity.

Amsoil is the best because it breaks down the slowest. Some diesel rigs go 1-200,000 miles between oil changes with amsoil.

I've used mobil 1 for years but I've read on a few forums that mobil 1 isn't as good as it used to be. Is Amsoil really as good as they think they are?

Amsoil is basically the best.

Pennzoil Platinum is basically tied with Mobile 1.

I've used mobil 1 for years but I've read on a few forums that mobil 1 isn't as good as it used to be. Is Amsoil really as good as they think they are? And these are the two oils I have narrowed down too. So I don't need any other suggestions. Thanks
