Tommy,
"First of all, what ae TD's?"
TECHNICAL DATA SHEETS presented by companies to demonstrate the basic parameters in which an oil or lubricant meets and commonly used to compare in the lubricant industry if an oil meets or exceeds a given spec by a manufacture or comparison of another oil."
"Second, it really is too bad that you consider the NOACK test to be frivolous "
Never said that, and obviously you are mis interpreting my comments as many do tech data sheets. Let me say it in another way... If your engine doesn't get any hotter than 190 degs but in maybe the heat zone in the ring area which an oil is only there for an extremely short time is maybe 350*deg's, and you have an oil that handles 445*'s verses another oil that does 490*'s, does it really matter? both are well over any temps used in a engine therefore it becomes a mute point as to how high the noack is if it is being used in a less demanding environment. Point is, just how dang high do you need for a flash point to exceed before you have accomplished the fact it will work in the engine without burn-off? Does that explain it so the picture has a little more clarity? No, I didn't say the astm#'s have no value just that a lot of you look at the astm #'s and have this uncanny way of saying, yep, that oil is much better than the other based on a few #'s because as we ALL KNOW, most every TD sheet available to the public is very LIMITED to ALL the TECHNICAL astm tests. So, as many companies like to do, take just a few little excerpts out of the limited #'s, and blow their horn on just that.
busterThere has to be some benchmark test. Take it for what it is I guess?? I more faith in API tests, and chemical engineers then people on the internet posting tests from there garages.
That has was a hit below the belt!, I think you like tommy are not seeing the whole picture.. Fact is, If comparison is what you want, get ALL THE #'s FOR ALL OF THE ASTM TEST DATA and COMPARE ALL NOT JUST A FEW #'s to start with. Oh yeah, there is more ASTM TESTS than just a couple that most post.. Get all the #'s together, get oil analysis together then lets talk about doing a real comparison. With only partial information about the tests, that's like hearing one side of a story where someone said you did it and the judge never hears your side therefore not ever getting the WHOLE STORY. Hows that for judging oil? BTW, FWIW, I have never stated amsoil or mobil are bad, just that the use of information on td sheets are nothing more than a starting point to looking at an oil, but ultimately, oil analysis will tell the WHOLE STORY where no one can just by the lack of info you have available.
