Oil Test by Street Commodores Magazine - dial up beware

Provided by the guys a SC.

Some very good reading.

This is the background info and testing standards.





Some of the resluts are very disturbing

Would be interesting to see these same oils tested after 10000k's in an engine. Looks like the Royal Purple stuff is the way to go for protection although they didnt test any Mainline products.

awesome, i've been running the penrite 5w60 in my last few engine oil changes.

Looks like my choice was a good one.

Thanks Animal great post, and perfect timing for me as I am currently cosidering what oil to run from here on in; and quite surprised by some of the early test results shown.

[aperfectcircle]

Thats a good right up I think

Might go for some royal purple next oil change.

clearly shows you how poor some oils "claim to be the best"

i guess the old sayings true . you get what u pay for and "oils ain't oils"

I have been using Royal Purple in my VS Ute (20w50)and my Monaro (10w40) since I read this article in March 2006. I was so impressed with engine oil, i also use it in my gearbox (Synchromax) and diff (MaxGear). It has made a big difference, especially in the ease of gear changes. I recently had my car tuned and the figures that I got even suprised the tuner. I told that I had Royal Purple all the way through and he said that it all helps. It's a bit hard to find so if your on the Sunshine Coast in QLD, PM me and I will give you the adress where you can get some.

I would have thought a lot of these oils tested would have been too thin for an LS1?

I believe SC admitted some flaws in their testing procedure shortly after publishing this. The conclusion was the procedure and testing equipment would be more valid for evaluating performance of grease etc rather than engine oil.
I am not a full bottle on tribology (study of wear, lubrications, friction etc ) so cannot personally comment. Although, I was a little skeptical when I saw this article. The results from experimental work are obviously dependant on the inputs so a little bit of knowledge can become a dangerous thing.
I know some of my friends have been involved in this area at university (Mechanical Engineering) and it is incredibly in-depth and complex. In fact people have phDs (Doctorate) based solely in tribology. I would suggest this information should be viewed with this in mind.

a fantastic write up. even if it isnt 100% acurate, it definitly give us a rough idea as to what is good and what is not.

[Nobby]

Wow, from a purely uneducated spectators view, it looks very much Royal Purple FTW, but Valvoline if you cant find the RP anywhere.

Could the motorheads around here explain if this is totally acurate, or are there other factors not reflected by this test?

[GHZ28]

Yes, this was back in about March this year when this hit the press, and they admitted later that the testing was more suited to diff and gearbox oils, something they did not know at the time.

They have said they would revisit it with testing more in line with the conditions in an engine, but so far I have not seen it.

No doubt, now that this has been raised again, 450kw Adventra will have a thing or two to say....

Awsome. Im going Mobil 1 next change see how that goes.

They wrote something in issue 116 that the tests they performed may be irrelevant.. They also said they would have a more indepth look at oil in the future showing why their tests were irrelevant..
Just happen to have my my copy of the mag in the desk drawer..
