Amsoil Gear Lube: No more Series 2000?

[Vaughn MacKenzie]

I usually use Amsoil Series 2000 75w90 in my Dana 80 but today when I went to order more it isn't listed anymore. Instead they suggested I get the Severe Gear 75w90, so I went ahead and ordered it although I didn't like plunking down the money for something I wasn't sure about.



Anyone know if this is the same as the Series 2000 with a new label, or another lube formulation?

Vaughn, AMsoil has upgraded all their gear lubes, and the "Severe Gear" has replaced the series 2000 lubes.

Does that mean that Amsoil has added more of their additives? The Amsoil additives are what causes Amsoil to fail API testing from what I understand.

the vast majority of amsoil oils are not API tested, which does not indicate a failure. They just didn't shell half a million to test an oil they've far more thoroughly tested, and didn't see the need for some cheesy tainted organization to give them their stamp of approval.



I read the article in the amsoil mag on the severe gear oil and it sounds like an improvement over the already excellent series 2000. I'll be adding it this summer when I change my axles out.

Thanks Wayne. As if it needed improved! Going nearly 40,000 miles on a rear lube change and having nothing more than a few MICROGRAMS of wear metals accumulate on the magnet and the lube still clean like new tells me it would be tought to beat that kind of performance



As far as the API thing goes, since it appears on Pennzoil products, it means nothing to me

Gear lubes DO NOT have API certifications! They DO have Gear Lube Performance and Classifications requirements set forth by API, OEM as well as Military specifications. API Service classifications include GL-1 (engine oil) used in some manual transmissions, GL-2 Worm Gear drives, GL-3 Manual Transmissions and Spiral bevel final drives, GL-4 Manual transmissions, spiral bevel gears and Hypoid gears, GL-5 Moderate and severe Service in hypoid and other types of gears, and MT-1 Nonsyncronized manual transmissions in heavey duty service (effects yellow metals without producing corrosive by-products).

Gear lubes also require the SAE (Society Automotive Engineers) grading system, AGMA (American Gear Manufactureres Association) and ISO(International Standards Organization) VISCOSITY is the number one characteristic!

When comparing SAE gear oil grades with SAE engine oil grades, the gear oil grade numbers are always larger. This may lead one to believe that gear oils are more VISCOUS (heavier) then engine oils. The truth is, in many cases they are not. An SAE 90 gear oil for example may have the same Viscosity of a SAE 40 or 50 grade engine oil.
