Sorry 'bout that Pablo, didn't know that you already checked. Thanks for trying again today though. What is everybody's take on this spec from them anyway?
Which Synthetic oil to use in my new Acura RDX?

Taking nothing away from PP, but if it is HT/Oxi type test and a group III oil can "pass" it must not be that tough. I know nothing of the actual specification, and if Amsoil does, they aren't saying. Something tells me it was NOT on their radar screen when I first rattled their cage, and they really didn't chase it down (due to other pressing matters no doubt....)
Anyway I will stay on it myself. The natives are restless.

Is this becoming a Honda Forum?
Anyway, GC is/was Factory-Fill in some of the most high-end TURBO Euro cars. The test sequence for the longer Euro specs is based on an 18k miles interval. So, imo use Mobil 1 on the 0w-40 (SL if possible) or try GC. Look also that Saab turbos use M1 0w-40 now and their previous "specific" oil was an A5 0w-30. PP 5w-30 is also an A5 oil. This is the spec I prefer for my Hondas.

It appears no one knows exactly what type of test this actually is, in terms of actual testing process. However, a little common sense says it's a oxidation/deposit test. None of the companies I've spoken with even know what it is, including Mobil tech. (not surprised)
The key for superb turbo charger performance is heat resistance, specifically the oil must withstand hot temperatures and not oxidize and form deposits. A PAO/Ester oil like Amsoil would definitely meet this spec. and I'm sure even a group III could if it's a good oil.

Hold the presses....this just in from HQ:
WOW...
(bold added by me)
I'm 1000% impressed.
Thanks for that Pabs. I'm getting ready to (finally) order some more oil from you and that made me feel alot better!
(The ATF for my Subaru we talked about, I was feeling a little uneasy with it just being added from Amsoil...)
Take care, bill
This is what I got back from Amsoil
Every answer is slightly different. They need an M1 group III type statement.....oh yeah, maybe not.
How come only one person actually knows what the spec is? And he died last year holding A-8 ♠.

I'm all for making fun of M1, but it was testing done by Honda, not XOM. M1 does do an excellent job of keeping engines clean though from people I've spoken with that have experience with it.
So according to this test, none of the other oils tested did that well according to Honda. What brands where they I wonder? Synpower? Castrol Syntec? Or did Honda use Home Depot 5w-30 to make M1 look good?
Amsoil will pass this test easily IMHO.
PP/M1 are the only two oils that passed this test as of now.
Notwithstanding the bias for Amsoil here.... Amsoil did not gain approval by Honda. M1 did. Bottom Line.
That's an incredibly naive response. M1 gained approval by passing the tests AND being part of a marketing deal with Honda.
Pennzoil Platinum is approved, too, but you don't see Honda touting Pennzoil. XOM paid for that Mobil 1 endorsement by Honda.
Putting aside all 'paid endorsements' for a minute, I'm very curious about warranty concerns where Amsoil (and Redline) are involved. If a manufacturer has specific requirements for oil to be 'certified' and G.O.D. forbid you have an internally lubricated component failure and are found to be using a non-certified oil (despite how good the oil is), are you giving the manufacturer grounds to deny warranty coverage? I'd be more than happy to pay the extra cost to use Amsoil or Redline, but if something happens, I'm not thrilled about the concept of Mazda telling me to get bent.
Can someone clear this area up for me? What certifications are Amsoil and Redline missing, if any?

Why is it when M1 passes a test, performed by another company such as Honda in this case, and all others are have showed to either have failed or do poorly, it's considered marketing?
Marketing is XOM showing the results and displaying them trying to convince it has a superior product. CBD makes a valid point and while I'm sure Amsoil would/will pass this test, I'd be very concerned about my warranty with this new HT0-06 spec. Let's give credit, where credit is due. That test graph specifically states "Honda R&D" suggesting that data is from Honda, not XOM.
I personally would NOT want to use any of those other brands, whatever they may be.

CBD - In that case, I'm pretty sure Amsoil would back it with their own warranty. Not sure of the technical details of it however, relating to different manufacturer specifications. I'm sure one of our Amsoil sponsors would be able to explain it further.
