I could have sworn I posted that info...perhaps I am losing my mind? Look at 2,3,6. The others are obviously relative and no min std is known to me.


And I do not live and die by API SL - I posted previously that many tribologists are not sure that the lowered levels of phosphorous demanded by the mfr's to protect their catalytic converters will provide the same level of wear protection as non-API certfied oils like Amsoil and Red Line. The GF-3 compliant oils used a new generation of anti-wear additives, but look at the huge gap between Amsoil and the others. The mineral oils in the wear test must all be buying the same AW additives packages from outfits like Lubrizol.

 

Good report RR. Reminds me of the days when I was working at Castrol doing oil trials. Road rage do you know of any trials that have taken place where many oils were tested in any kind of engine and cylinder wear data was collected ? Still looking for this info on the net.

Rich.

 

No. You might check the SAE research librarian. Mobil did one on its own product, and it showed little wear at 200k miles - so extrapolate that and imagine what an oil that measures better might do?

Over the road haulers using Amsoil and bypass lubricant have gone 1 million miles. Mny truck mfr's will warrant their trannies/diffs for 1 million miles if they using approved synoils - the drain and fill plugs are replaced with no tamper types!

Some of the new BMW automatics come with no fill plugs!

BTW, Volvo has designed a car for women - a team of women engineers and product developers worked on it. It calls for 30,000 mile OIL change intervals! It is essentially maintenance free, and transmits to the dealer a service call when needed. Hard to believe, no?

And Visteon has a 150k air filter design.

 

Nope. But GE uses an entirely different business model than Amsoil. I do not feel it is a good comparison. GE has segregated itself into many prodcutive businesses. Somthing tells me they won't be pushing their jet engines on me if I order a refrigerator. I can also go to the closest home improvement strore to pick up a GE refrigerator whereas there is no auto store to my knowledge in a 30 mile radius of my address that carries Amsoil products. And if Amsoil was so great and so wonderful, like GE refrigerators, shouldn't it be falling off the shelves anywhere I go?

This is sort of a red herring argument - indicting the product for issues that have no relation to it. The facts of the tests speak for themselves, and as I already commented, it is corroborated by both independent analyses I have run over the years myself, results from others I trust, and can easily be impeached if someone wants to run other tests
The gear lube test I posted a while back was run by an independent laboratory with unimpeachable credentials, and it showed their gear lube at 3X the test sequence performing better than Valvoline NEW.

 

interesting

 

Road Rage, sir you are a most welcome member of the s2ki community. thank you very much for this comprehensive information and analysis!

 

This is excellent information - thank you very much for compiling it! Here's one vote to make this a "sticky thread" at the top of the page.

 

oh and let me go ahead and sum up all that mumbo-jumbo for us S2000 fanatics

If you love your S and plan on keeping it forever, PURCHASE AMSOIL BY THE CASE.

(do I hear Group Buy?)
