Auto & Truck Oils, Lubes & Filters – Separating Technology from Hype

Good thing Amsoil doesn’t stoop to API Licensing

Irresponsible and unqualified “maroons” too often leave ugly trash commments on vehicle forums, making grossly incorrect statements about Amsoil synthetic oils that just infuriate me. Like this classic gem from the Slant Six forum: “Don’t let the Scamsoil droids convince you their expensive gunk is superior to properly-tested, properly-certified regular or synthetic name brand oil.” Or over at Ford-trucks.com you find “Most of Scamsoil’s products ARE NOT API certified!!!! Sounds like you have been reading the lies on the Scamsoil website, stay away”.

If they were merely sharing their opinion and stating their credentials, people wouldn’t have much heartburn over it. But to make false statements like that, irresponsibly leading people away from the superior performance and lower costs of advanced technology, gets me irate.

So, for the record, let’s establish qualifications before we talk about facts. I’m a B.S. degreed Mechanical Engineer. I’ve been in industry for more than 20 years, the last 5 as an engineering manager, and have spent more than the last 10 in the Tier 1 and Tier 2 suppliers, where most automotive parts are made and a lot of value-added engineering is done to improve the products and manufacturing processes. As a matter of fact, while the OEM has some involvement when a subassembly has a defect, guess who is required to do an “8-D” root-cause analysis, implement corrective actions, and monitor to make sure the CA’s are effective and it can’t happen again?

In 2004 I bought a 2002 GMC Sierra with the Duramax turbodiesel and Allison transmission package. That was the beginning of a journey of extensive personal research into vehicle drivetrain lubrication and filtration, and a growing passion to tell people the astonishing facts I learned. I became an Amsoil dealer, not only to help people get literature and best pricing, but to continue learning.

Opinions are as worthless as armpits – everyone has one, but most of them are smelly. And you can see some of the smelly opinions in detail on this “scamsoil” page for Amsoil skeptics, which corrects Amsoil myths using facts.  I tell people what I know, and the conclusions I can reasonably prove with facts and data. So let’s talk about facts. But before I can get far, I have to explain the common sense backdrop to correctly “frame” the facts.

I find it interesting how one-sided the online forums often are: if an Amsoil dealer makes a statement, he’s often dissed, disbelieved, and ridiculed – even if he’s an engineer. If he’s not a “supporting sponsor” of the forum who is paying for the right to make “commercial” comments, he may get warned, censored or kicked off by the moderators for “advertising” helpful facts or suggestions. However, no one seems to question if naysayers have ever worked for petroleum suppliers, if they have an engineering degree, or if they have had training sponsored by “big oil” – and they aren’t required to be a paying sponsor to make glowing recommendations of petro oils. Couple that with a forum’s discussion environment of one or two pararaph comments, and the deck is strongly stacked against open an discussion of engineering facts and test data.

Executive Summary-in-One-Paragraph of the
Facts on API Certification of Synthetic Engine Oils
Under Their EOLCS:

Unfortunately for consumers, the API has no Certification for high performance: only minimum performance. Further, the API provides no reasonable certification options for genuine Group IV and Group V synthetics, deliberately maintaining a skewed structure that multiplies synthetic test costs by several times. In addition, the API Certification adds content restrictions (not required by the SAE, not required by the OEM’s) that prevent long drain intervals and prevent very low wear rates. So the world of API Licensing implies that high-profit mediocre products are high performance, it ensures that only petroleum-company oils can be cost-effectively Certified by the API, and it ensures that the world’s highest-performance products cannot be API Licensed/Certified at all. Fortunately for consumers who want high performance and high value, the API Certification monopoly is a voluntary trademark Licensing program that does not matter in vehicle warranties.

Now, that’s stunning information for many people.  So let me clarify:

Close examination of the OEM Owners’ Manuals shows that engine oils must meet the API/SAE Service Grade requirements that the OEM states.  Continue reading

Differential Fluids, Differential Covers, and Towing.

OK, what’s the real scoop on differentials?  What do aftermarket differential covers do for you?  Should you buy one or make it yourself?  When should you worry about it?  When do you need a temperature gauge for your differential?  Those questions and more came up in a recent online user forum, and the experts’ answers were excellent.  If you do any towing, I believe this information is critical for you.

OEM’s agree that to maximize your differential life you need to do your first fluid change at 5,000 miles, and lubrication and drivetrain engineers will add that a high-performance synthetic is the best and longest-lasting choice.  Maybe you’ve heard that, but what synthetic should you choose?  Remarkably, there are downright embarrassing differences in the tested performance of gear lubes on the market.   In fact, using the wrong one in a towing application will probably take your differential into early failure.   You can download a free research study detailing the performance testing of 14 name-brand gear lubes.  Think it doesn’t matter much?  On the contrary, we found it very disturbing that over half of the name-brand gear lubes failed one or more of the standard performance tests.

That study is also excellent because at the beginning, as background, it outlines the results of operating-temperature studies done on differentials in towing applications.  The information from those studies is eye-opening.  So enjoy.  And remember, your entire vehicle and towing load rests on TWO GEAR TEETH in your differential: your gear lube choice is critical !
