I gotta ask a few things. Thanks for this thread, by the way...I don't know anything about this and I learned a lot thus far. But Claudius is running Castrol RS 5/60 ?!?! What's with that. It seems so high-viscosity and even though it's going to protect the engine like crazy, is it really down to 5wt at temp or are you losing tons of HP?

thats a huge range...
meaning a ton of additives and thus a lot of deposit.
I'm sure it covers the range, maybe not well, since with all that additives its gonna breakdown a lot easier. BUT if you change it early, it probably hasn't broken down yet. Who knows short of running some lab tests.
Mobil 1 has a 15W50, use that if you want protection at the hotter temps... probably great for summer time!

Taking advice from someone who writes stuff like this:

Anyhow, here are some cars which DO boost: Porsche 911 Turbo, Porsche Cayenne Turbo, Aston Martin DB7 Vantage. They all have seriously expensive engines and they all produce serious power stock - over 400 hp and over 400 lb-ft of torque. And they all come from the factory filled with Mobil 1.
Most so-called engine builders are clueless about tribology. Heck, they probably don't even know what the word means.

Tribology
Oh hell, even I know what tribology is...and I don't even build engines. It's the study of the history of the little furry creatures, tribbles, that infested the starship enterprise when Kirk was still captain. Don't play US for ignorant! HA!

I dont think I'm losing that much hp: a friend of mine's got the same setup as me and the same 410 ft/lbs and bhp numbers. I dont know what oil he uses, though. I guess the Mitsubishi recommended oil is ok for stock engines, but then again, it's your car and your choice

First thing I did. Dyno oil is the best way to brake a motor in. It can't hurt.
This is the first EVO to ever have Syn. from the factory.
10/30 dyno for the first 3K and then a fine Syn like red line is my plan.
I support ya buddy!
Built a few motors my self.

About this turbo vs NA oil thing. So Boost Solutions is saying don't boost with Syn oil because of the extra pressure on the cylinders. But don't NA motors have significantly higher compression? Creating ALMOST equal 'cylinder pressures'.

Another example is to large of a exhaust on A na car will lose Tq because a NA car needs some back pressure to increase the cyl pressure.
8.8/1 static compertion (EVO motor)
10.5 / 1 Static compertion to a 330ic
8.8/1 Static compertion + 19 Pounds per square inch = much higher compertion then 10.5/1. I don't know the formula off the top of my head but under boost compretion is around 14/1.
That's why we turbo charge cars
