Synth oil change for US$44.99? - Is there something wrong here?
What base stock is it made out of? What type of additive package does it have? Have you found any data online that shows it's decent?

Unless you have been closely comparing oil analysis results for Amsoil vs Royal Purple.

I figured why not and i gave it a try.
I can say this about amsoil that after driving my old car hard for 65k miles. Opening up the head revealed no gunk buildup and all engine components looked great. Unlike someone who was using conventional oil had more miles then me..not by a lot and he had soo much crap inside the his head. Driving styles were identical.

If i am not mistaken the show trucks on Spike TV did a comparison before and after the swap to RP and they showed drop in engine temps. Being that the car was ran before and after oil change.
Good info mygspot. What type of oil changes did the conventional oil user use? If he used a 3,000 mile oil change, I'm surprised he has gunk and varnish. If he pushed out to 5-7k, then I can fully understand.
Amsoil is great stuff. Pricey though. And not quite easily available enough for me. I just use Mobil 1 in the 5qt jugs from WallMart.

I agree that amsoil is hard to get. Around me i accidently ran into an independent dealer and started buying stuff through him. otherwise you can always order directly from the company. Now that i switched to RP its available at pepboys.

IMHO and to what I have seen, Amsoil still out performs RP, Redline and Mobil 1 in wear tests. I try to keep up with BITOG forums on tests but when I was reading it, it was known RP actually caused more wear overtime they Amsoil or Mobil 1.
If youre gonna spend 12 bucks on a filter then you should just get the Mobil1. It's filtering capability has been proven time and time again. The K&N is another good option in that price range, it has a better flowthru but is less efficient at filtering. You can't have everything, they are contridictory to themselves, either you get free flow or high filtration.

really good stuff, and its a full synthetic, not a blend

a quick faq on the oil
Basic information:
What is GC?
GC stands for German Castrol. It's officially named Castrol Syntec 0w-30.
Produces great UOA results.
Engines run quieter and smoother. (OK, that may be an opinion.)
Comparable price with other synthetics. ~$5 qt
GC is a TRUE synthetic. Made from PAO/Esters, not Group III.
The other Castrol Syntecs are not true synthetics.
Other examples of true synthetic oils are Mobil1 , Amsoil, Redline, and Royal Purple to name a few!
GC is good enough to have its own forum! That's gotta mean something.
What's bad about this stuff?
Not much.
You might have a hard time finding it depending on where you live.
Your car might not like it. You'll never know until you try.
Keep trying oils until you find one you're happy with.
Addicting. You'll see what I mean...
Is it "thin"? Come on, 0w-30 has to be watery.
NO! Please don't completely buy into that myth.
At cold temps, the 0w weight correlates to cold cranking viscosity.
That means GC will still flow at cold temps. (Which is a good thing!)
At operating temps, the 30 weight is actually close to a 40 weight.
GC is one of the thickest 30 weight oils around.
I don't want to go into too much detail about this here. It can be very confusing.
My point is, GC is not "thin" in most temperatures that we use our cars in.
