And for any one who might not be aware, 0-20 is molded right into the oil fill cap of the FR-S.

When speaking of Amsoil, note that their OE and XL lines are made from Group III base stocks. Of course, what matters most is the complete package (base stocks and additives) and the oil's end performance.

DaJoian - Can you check if the oil is API SM or SN? Just curious.

It's "API Service SN"

for those of you doing lots of track and stuff like that, motul, IMO, is way better than even amsoil or penzoil or even redline. I personally try to use redline as much as possible and motul in my max effort vehicles, or ones that will see a lot of abuse. worth the expense in my mind.

Wow, haven't seen the SN yet. And U.S. dealers are still getting in plenty of SM. The SM has higher levels of moly.

Sorry for asking this stupid question... but which one is better and what are the advantages over the other?

Motul. Ester based oil.

Moly is an excellent friction modifier and anti-wear additive which is why it's found in very high levels in racing oils like Red Line and Motul 300V. Generally it's being reduced in the new API SN/ILSAC GF 5 oils for emissions requirements, although Mazda just came out with a Mazda branded SN/GF5 high moly oil.

Yikes... Would you say I made a mistake in changing out the factory oil a little too early?...

I really don't know. Some people say moly aids the break-in process and some people say that it doesn't. Over at subaruforester.org, there has been an ongoing oil consumption thread since June of 2011 for the new engines that use 0W-20. Just a couple of ideas that I have had are breaking in the cars too easy (according to the manual) or changing the factory fill too early. Most DIY'ers always change their oil early. Everone is like; "ZoMG i have to get out the mETal bits beFORE the enjine assplodes!" In addition to moly, the factory fill has higher levels of zinc and phosphorus as compared to even the dealer Subaru/Idemitsu oil.

This is what Idemitsu Lubricants of America emailed to someone on another forum when he asked about moly in the factory fill vs. the dealer oil:

You ask some very good questions which I will answer in “generalities”. First, just so you know where the information is coming from, Idemitsu supplies most of the OEM’s for both Factory fill and service fill. In the case of Toyota, we do not supply their service fill oil so I cannot comment on that particular formulation.

OEMs specify Moly in their factory fill formulations to increase fuel economy during the initial period. In general a factory fill formula will be more robust in the additive treatments etc. This is done for a variety of reasons which I will not go into here.

Some of the service fill formulations also contained molybdenum however, with the transition to the ILSAC GF-5 specification, most 0W-20 service fill 0W-20 formulations now do not have Moly. That being said, you are always safest following the OEMs recommendations. All service fill OE formulas that we supply have been submitted to a full battery of tests at that respective OEM’s R&D facilities in Japan and have been approved.

You can also buy moly at NAPA.

Any Subaru branded oil that is API SM/GF4 (old specs) has a lot of moly.
