Actually, I would probably run Red Line 0W-20 over any Resource Conserving 5W-30 in my FI boxer. As quickly as some RC 5W-30's shear, Red Line 0W-20 will probably have thicker viscosity after severe condition usage than some 5W-30's.

RL 0W-20 is 9.1 cSt's. You can find many WRX uoa's where a typical RC 5W-30 has sheared to a thinner viscosity than this in as little as 2,000 miles.

PU 5W-30 actually holds up well in WRX's in mainly stock, highway (easy) driven cars (based on several uoa's by KHP on bitog). As for Amsoil, HDD 5W-30 Series 3000 is a very robust oil. The Amsoil SS, XL, and OE 5W-30's are typical girly man oils (with SS being slightly better but still shear prone).

My dealership has been using Toyota 0w-20 synthetic and I've used M1 0w-20 AFE synthetic in between dealership changes. Multiple track days, autocrosses, and daily driving. No problems so far and the engine seems to run stronger as I put more miles on.

[Antheezy]

Im using Mobil1 5w-30

[benlaz88]

Im using Eneos 5w-20. Running great and 30MPG (city only) with K&N drop in.

Total 9000 (5w50), best is to have oil temp & oil press gauges then we will see the diff of the oil performance @ diff weather temp.

[BRZnut]

Kept Factory fill in for 4000 miles-->dealer change once and used Castrol--> I'm now changing myself and using M1 0W-20.

I too experience a much stronger engine as the miles accumulate. Evo magazine experienced the same thing. After a few thousand miles the car becomes much quicker, around one second quicker 0-60.

After reading the UOA threads, I'm going to stick to Subaru 0W-20. Looks like great stuff!

Not sure if it's "new oil" effect, but engine seems to be quieter with Eneos 0w-20 oil (not sustina).

I really don't care which brand I use, whatever is available. Mobil 1, Motul, Eneos, Castrol, Redline.

I recently did mine and went with Penzoil Platinum 0w-20 and the OEM Subaru filter.

[Rayme]

Nothing but 0W-20. It's an amazing weight oil for Canadian weather.
