I've realized the Mobil 1 I've been using is basically crap (HTHS of 3.1 for 5W30) I've read great things about Redline and would love to use it but it seems retarded expensive and hard to find. I also read that a lot of people are running Rotella T6 but because it only comes 5w40 it results in higher than ideal oil pressures.

Is anyone using an economical synthetic oil available locally or at least in US big box stores that has HTHS numbers closer to the 3.8 of Redline in 5W30?
Just go to Costco and pick up a cheap case of Castrol Edge and stop worring! You're putting WAY TO MUCH thought into this!

Now if you owned a highly moded turbo Subaru or even a Porsche/Ferrari/Lambo, then your question about proper oil would be more valid/important.

For what it's worth, I change my oil twice a year (6 months). Once in the fall and once in the spring on my 2011 STi.

Spring = Rotella T6
Fall = German Castrol 0w30
Both I get at Walmart.
