Looking to explore for new motor oil

Currently I'm using German Castrol 0W-30 and I'm gonna get a UOA on it so I'm looking to venture out try other oils.

I've been looking at Amsoil and they have the Signature series 5w-30 and the European Formula 5w-40. Also Motul 8100 has X-Max 5w-40 and Eco-Clean 5w-30.

Also, vendors feel free to chime in on what you recommend.

Mike the Aussie convinced me to use Total, once I found out Blackstone likes it.

Redline or Amsoil - quite simply the best stuff I've ever found.

Honestly, the signature series Amsoil I think are unnecessary for STI's. With our short oil change duration, the extended life oils are a waste of money.

I run on 5W30 Amsoil

Looks like I have more choices now than ever!

So with viscosity, is better to go with a thicker 40 weight oil vs 30 weight that Subaru recommends?

We use Amsoil 5w-40 in most cars. Great oil all around.

Good to know!

Thanks guys for your input. I'll eventually get around to trying them all and seeing how they perform.

DO NOT use a thicker oil
The majority of wear occurs at start-up while the oiling system primes. The thicker the oil, the longer it takes to circulate.
Heavier oils are a holdover from the days of natural base racing oils when they needed a high viscosity to prevent thermal breakdown. True Synthetic oils have a much higher heat tolerance than any natural base racing oil

Rotella T6. There is a big thread on Nasioc about it and its by far the best oil according to all their tests. It all looked like jibberish to me but apparently it holds its viscocity for a very long time or something.
