Amsoil, is it worth it

[Marlin]

I think mobil 1 is very Nikeish. Nike shoes are not all that great, but their name carries them on, like Bose, and other premium brands. You are paying some fee for that Mobil 1 sticker.

I got this from Amsoil:
NOACK volatility test (how much it burns off over time)

Amsoil:5.44%
Castrol GTX-6.77%
Quaker State-6.97%
Mobil 1-7.49%

In the wear scar test, mobil 1 was last as compared to the following in order from #1 to last
Amsoil
Pennzoil platinum
castrol syntec
motorcraft synthetic
quaker state sythetic
havoline
mobile one(over double the other brands)

Filter efficiency:
Amsoil-98.7%
Premium synthetic brands, Mobil 1-80.23%
Conventional-39.39%

And from the makers of Amsoil also comes NGK spark plugs, which we all know and love. They also do the arfilters for Injen intakes.

Tranny fluid test, leading synthetic brand(undisclosed name) lasted 450 hours until breakdown, Amsoil went to 900 hours and still no breakdown.

I would compare Amsoil to slick50. If you are okay with spending the money, go for it. I am definitely ok with it for once a year oil change, especially in my expedition.
