Some interesting Timkin test rig oil test results

[XS650]

I ran across this link in the Corvette Forum.

The test results are interesting, but like the infamous 4-ball test not necessarily as meaningful as the tester would like you to think. Still, there are some BIG differences there.

Got a friend who got to see this test in person. Royal Purple put it on.

He said the test leaves out a very important variable.

Heat.

 

[Master ACiD]

you guys think royal purple could really be that good? i thyink it was a fake test.

 

[XS650]

Thanks, MrC, that 'splains a lot.

That reduces it from interesting but not particularly applicable to IC engine to something less than that.

Look at the Royal Purple UOAS that have been posted. That is the real indicator of how good an oil it is, not a carnival sideshow "test."

The test is an excellent test if you are never going to start you engine and get the oil hot. If you are going to design you engine so that shafts rub against other shafts instead of being mounted in bearing journals this is the test for you. You can conclude that if you have splash lubrication at room temperature and have no spinning shafts running in bearing journals than you should pick from their list of best performing oils. If you have a standard internal combustion engine the choice of 'best oil' is a bit more more involved.

No offense but this has been posted numerous times.

The problem is that people are impressed with the test and it sells engine oil and additives. It's a test you often see at the country fair. It works as a sales tool, every time. At the Del Mar Fair there was such a booth selling an additive and people were buying.

 

[daman]

yep, poor fools.

 

[Master ACiD]

who buys additives at a fair anyways? i wouldnt buy any car stuff at a fair no matter what because its a fair and theres too many snake oil salesman in this world. i would expect people selling additives to have nd30 in a slick bottle.

That is very true. Their are good as well as not so good UOAs with Royal Purple just as there are with all other oils. One UOA is about as accurate as the test performed on the "one armed bandit".
I do not think the test was rigged at all and I don't think the test applies directly to internal combustion situations. It does however prove that RP was the winner of the oils included in the bandit machine test which I guess isn't important unless you own one of those machines and want the best oil to use on it.

On our Timken after a short while the oil is boiling. The friction heats the oil rapidly. I still remeber the oil that blew away the guy doing the tsting at the endo of the night, Ron now my good friend. From what I'd seen earlier in the night I expected nothing from a bottle of oil I had in the car. It was thinner than anything tried yet it quietly did it's job and went past 100lbs pressure for the first time ever easily setting a new record. How could this 'water' smash anything ever tested? It was a few yesrs back and few have bettered it even now. It was from Mobil, anyoune care to take a guess what it was??

You've got a friend in Oz.

Cool.

 

[sprintman]

Heat is generated instantly you start. Think of the friction. Poor oils boil off qiuckly, sure ain't no lack of heat that's for sure

If that test worked this site would not exist. There is more to a good engine oil package than performance on this test. I put this test in the same context as many of those TV commercials about engine oil, entertainment at best, but nothing more.

Yea, and I was hoping for a different result

 

[gundog]

I wonder why Amsoil was no included in their test? While the test in lacking in many aspects, iIt still would have been interesting to see how Amsoil would have compared.
