I believe these results are produced by Amsoils own lab (probably done properly I would agree ) however, it is Amsoil's lab. This does diff from an independent lab ( with a reputation at stake supposedly for not giving bias) even if it was paid by Amosil to do the tests.quote:

I see no reason to assume, or even suspect, that Amsoil rigged the testing. But, I also see no reason to believe Amsoil would've published the results if their sponsored tests (presuming the testing lab's objectivity) hadn't ended up favoring Amsoil products' alleged superiority, either. (Duh... - begs the question how many other comparative tests have been run over the years that Amsoil made sure never saw the light of day in print?)
JohnBrowning, what is the NOACK % for Castrol Syntec 5W-50? I sent Castrol an email requesting this information about a year ago but they said that information was proprietary.quote:
2KBMW, Are you useing Syntec 10W30? I ask because these numbers mean nothing if you are useing the 5W50. I would also point out that out of 7 tests Castrol did better on only 3 of them. I do not know that can really be called much of a victory if they only bested 3 out of 7 tests. To add insult to injury the 5W50 that most used of the line up has the worst NOAK of any so called synthetic I have ever seen.

Most drugs are approved based upon the reuslts of multi center trials etc, what few people know is how many actual patients were involved, sometimes only a few thousand. If you read the inserts (which few people do)though you get the entire scoop. How many people get a presciption and ask the doc about all the possible side affects? Many docs don't know all the facets of the drugs they push (may not even run tests on the patient) and are similar in some ways to those that sell motor oil (never examine the engine)prescribe a specific oil and inform the consumer to go 25,000 miles between changes
QS just recently started advertising their synthetic 5w30 and 10w30 as being A3, so it's only their latest formulation, and I'm sure this test must've been done with their older formulation.quote:

I thought the Q.S. 10-30 was A3 rated. How can it have a lower HT/HS than M-1 or even some conventional oils (like their own Q.S. Peak performance)????? Are these stats accurate?
The stuff I see around here all says SL formula on it, but doesn't say A3 rated, so it's probably a reformulation done midway through the SL cycle. Speaking of which, I guess we'll be seeing SM formula oils coming out sometime later this year?quote:

Aren't the new specs ref. to SL formulation? Isn't the Q.S. synth SL 10-30 version the A3 one? Or are we on the second SL formulation already?
I don't think that the current Quaker State Synthetic 5W-30 and 10W-30 is rated ACEA A3. If you look at their tech data sheet it states: "European ACEA A3-98/B3-98 engine test protection standards (5W-30 & 10W-30)." It does not state that it actually meets the ACEA standards for the out-dated A3-98/B3-98 standards from 1998. Perhaps Gman-II or another attorney will comment on the wording of their statement.quote:
