I had my Rotella Synth 5W-40 tested last oil change. I ran it for about 1.5k street miles with 1 track day and everything looked great. This is from a slightly tuned STi (17-18psi on the stock turbo). So I wouldn't be worried about running the Rotella on the track.

I would stay away from 30 weight if you are going to be seeing a lot of heat/boost. My tuned STi seems to like RTS 5w40, I recently had an OA done on it and everything looked great. I only had 1.5k miles on the oil but there was also an hour and a half of track time. So I would go with a good 5W40

I'm running Rotella synth 5-40 on my slightly modded STi. I had it on the track for about 1-1.5 hours last week and it didn't use a noticable ammount of oil. I plan on running this oil for ~3k total and getting a UOA. But so far so good for RTS!

Wow, amazing car...

And as Doc stated, the power level I'm running is nothing for these cars. I'll probably end up using Rotella and sending it in for a UOA. If it comes out good, I'll keep using it; if not, I'll look into Motul or another good synth.

My mods are: Invidia V2 DP (bellmouth) Maddad Whisper CBE (full 3 inch, no tapers) APS 65MM CAI 3 port boost solenoid and I have a dual catch can set up that I'm still working on modifying and figuring out where I want to mount them, I should have these installed before I hit the track. The...

Thanks for the quick replies guys! Great info. ProjUltraZ, yes the 2.5l turbo subies are pretty fast, fast enough for me at least (for now...)! The car is spec'd out for 5W-30 and the Rotella Sythn is 5w-40. I doubt this will be a problem though, don't a lot of car companies spec 5w-30 to get...

I'm was planning on switching my slightly modified 07 Subaru WRX STi to Rotella synthetic. I just wanted to hear everyone's opinions first. Incase you don't know, these cars come with a 2.5l turbo horizontal motor, they make ~300hp stock. I bought the car new and have been running Castrol dino...
