I ran my sti 8 block on millers 10w50, what power are you going for?

 

hoping for between 350 - 400, or am i being optimistic?

 

What turbo?

Have a look into some new-ish stuff called Royal Purple.

Judging by the tests being done on it, it out-performs almost every thing else and some stuff three times the price.

 

Yes, those tests show that Royal Purple is absolutely amazing oil, but when they are sponsoring the tests, the results aren't ever going to go against them. There's several tests doing the rounds on the internet, but they are all from RP.

We had some of their oils chemically tested and we weren't impressed. Most of them contain high sulphur levels, which combined with high temps can produce acidic compounds, the last thing you want around the metals of your engine.

 

Millers 10w 50. Excellent quality oil that all my Imprezas have been using it.
