Is the RP scar test the same concept as the 4 ball test?


NO. 4 ball wear is an ASTM test. It's somewhat repeatable. It is correlative to point wear which admittedly is not a frequent occurrence in ICE's. In some ways it is tougher than engine situations, in some ways it isn't.

The "long arm" machines are the real joke.

I'm assuming you mean "call out" as in what BP did to Royal Purple. Correct me if I'm wrong.

No one can do that because Amsoil never explicitly makes the claim that the test corresponds to engine wear. They just say "Here's this test. Our oils do better on it. Also, they can protect your engine." Nothing false or misleading there, at least as far as the lawyers are concerned...


Antics with semantics I guess. If the test has no validity with engine oil, then it should not be allowed in an ad. I guess all companies work things to make them look better than the competition even though the tests are sometimes totally useless. I like the product, my father uses it, but I find it hard to respect a company when they use these misleading tests to lure in uninformed people. But that's business I guess!

But it does, so that's the rub.
 
For Amsoil it does for Mobil it doesn't, and a lot of members are claiming it has no bearing either. Who do you believe?

They could use those additive packages in any lube though, including gear lube.

No it doesn't - and why do people on BITOG keep repeating this?


Because by making that statement they are digging on Amsoil. (IE Amsoil is as good as bleach)

If they are not posting about their flavor of oil they are digging on any other oil that is not theirs.

Same with brands of vehicles. Toyota vs Honda, Ford vs Chevy, dogs vs cats...

There has to be a way to keep up with you guys for message counts!

The add pack itself?

Comparing add packs in the same base oil?

Either way, what exactly is the correlation? We can't even reliably predict the properties of a finished oil from the base stock. How are we to make reliable predictions based on one characteristic of the add pack?

That's another link in the chain, but it's not the whole chain. Connect the dots for us.
 
What motor oil fails the test and what is pass fail for the test for motor oil. Could the Amsoil experts tell all.

Significance and Use

This test method can be used to determine the relative wear preventive properties of lubricating fluids in sliding contact under the prescribed test conditions. No attempt has been made to correlate this test with balls in rolling contact. The user of this test method should determine to his own satisfaction whether results of this test procedure correlate with field performance or other bench test machines.

1. Scope

1.1 This test method covers a procedure for making a preliminary evaluation of the anti-wear properties of fluid lubricants in sliding contact by means of the Four-Ball Wear Test Machine. Evaluation of lubricating grease using the same machine is detailed in Test Method D 2266.

1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

Four Ball Wear Test ASTM D4172
The Four Ball Wear Test ASTM D4172 evaluates an industrial gear lubricant’s wear-preventing properties in steel-on-steel sliding conditions. This test is not intended to predict wear characteristics with other metal combinations other than steel-on-steel and does not measure the extreme pressure characteristics of the industrial gear lubricant. The Four Ball Wear Test ASTM D4172 utilizes the same test apparatus and set-up as the Four Ball Extreme Pressure Test ASTM D2783. The test is run at 1,200 rpm under a 40 kgf load at 167ºF (75ºC) for one hour. After the one-hour test period, the three stationary balls are washed and the wear scars are measured to the nearest 0.1 mm. Another set of measurements across each scar, 90 degrees from the first, is then made. The average of the six measured scars in millimeters is reported as the average scar diameter.

The lower the scar diameter, the higher the level of wear protection the industrial gear lubricant will provide under sliding conditions. When comparing the capabilities of industrial gear lubricants, the results obtained in both the ASTM D2783 Four Ball EP and the ASTM D4172 Four Ball Wear Test should be considered. Some industrial gear lubricants that have good extreme pressure properties may not be effective in reducing wear rates at lower loads.1

Yep - right up there with those guys lighting hoods on fire to prove a wax is durable. Truth is the alcohol burns fast and doesn't generate any heat at all to damage the paint. Clueless people still buy into that junk wax.

As buster shows in his quote, there is no pass/fail. The tests are for evaluation. Someone comparing ASTM tests to "guys lighting hoods on fire to prove a wax is durable" is demonstrating they are not so knowledgeable.

Wear test? No sure there is one.
 
It seems to get harder and harder every year to educate you newbs!! Why not listen to the guys that have been here for years and who have significantly more experience?

I've been here over 3 years and have barely a fraction of the knowledge Pablo, Bill, Buster, etc, have.

If you want to troll, moan, or play "my-fav-flavor-boy", do it on another forum where it might pass for intellectual discussion

WHAT!

You mean that wax that still beads water after fire is NOT the BEST!!!!!

(Now they tell me......)

PS: Just kidding. I've never bought wax off the TV or internet.
