I ran Rotella on my built engine. Didn't like it. It made it run considerably louder.

^yah I was thinking of running rotella since I've been reading nothing but good things about it for our engines....also remember reading a few mentioning about how much louder their motor was....

U think a higher weight oil will benefit me since my motor is stock, daily driven 45-50 min to work and back and this is all highway driving no stop and go traffic?? My main concern was the 30 weight shearing down since my trip to work is fairly long especially with the turbo probably running at a high heat...I figured the 40 would provide more protection with higher temps

I'll share my experiences. I have used Amsoil XL 5W-30 for most of my cars life. It's an 04 STi with about 52k miles. I live in upcountry Maui so my commute is roughly 50 miles roundtrip, but the drive home climbs to about 3,600 ft above sea-level. I drive roughly 40 45 minutes one way.

I have had good experiences with Amsoil. My car does not consume any oil between oil changes and the oil temps rarely exceed 220 degrees on the hottest day and usually stay just above 200.

Just switched total 5w40...pretty smooth....I used to use rotella, i think the total is smoother.

i currently run with rottela 5w40 no issues, runs like a champ although i only have about 6k better run like a champ
Im probably gonna try something different my next oil change to see if i notice any difference in noise.

I have a 2005 STI, Currently at 140K I have tried Valvoline, Mobil 1, Mobil 1 EP as well as Amsoil Signuture series 5W-30's. Vavoline was buy far the worst for burning --Burned almost a quart every 1K. Mobil 1 EP and Amsoil burned were best only burning about a 1/2 Quart between changes/ every 3K

I currently use Penzoil Ultra 5w30 in my '04 WRX motor. No problems. I hardly notice losing any oil between changes.

It just holds up better in the turbo EJ motors. It's been pretty well proven that thin or easily thinned xW30 grade oils spin bearings. A robust 30 or decent 40 grade oil is a safer bet, IMHO.

Pennz platinum
Castrol (german castrol)
Certaain Amsoils and Motuls
others that elude me...check BITOG or the bajillion oil threads on nabisco, too.

you trying to keep under warranty?

^yah I've been doing a lot of research but I wanted to see what the guys here in Hawaii use because climate and weather differ from the mainland and what works for them their might not work for us especially with the elevation here on the big island.....warranty?? I'd rather be on the safe side but on the other hand I'd like to use an oil that will provide longevity and better protection for my motor even if I had to run a 40 grade oil....the only thing that im concerned with rotella is because its made dor diesels an ive read that some of the chemicals cause the catalytic converter to become less effecient....tried RP but I dont like it...
