ON Magazine's article on oil?
[QUOTE=Mika;863316]I have not read the article; however this thread has moved it up on my to read list. I have read this thread (at least through the point I left to bang this out) and frankly donÔÇÖt get the thread.
Is it an oil thread about an oil article? If so there has been precious little about oil and a great deal of credential posturing while attacking the author and his writing product rather than the underlying data and conclusions. Silly me, I thought the critical thinking process in things like this is to focus on the data or conclusions and vet that in the discussions.
Is it a thread about technical writing/editing? If so there is a dearth discussion of how to structure an article (introduction, body, conclusion), a paragraph or even sentence structure. As owners of the Owners News you are publishers so where is the publisher discussion of editing of technical, or at least non - how I spent my summer vacation articles?
And you guys wonder why Vince has trouble getting technical articles.[/QUOTE]
Awesome. A review of a thread that reviews an article you haven't read.
Purpose of the original question
First of all, I DO commend the author of the article for the sheer amount of work put into the project. What I was questioning was the explanation of all of that overwhelming data. Still, having read the article carefully 2x through, I am still at a loss on how to "evaluate and come to my own conclusion." I think the article could have been much better if it had taken each of the test criteria, and then said something like this. Oils with higher ZDDP are better for these types of applications...and so on through other data as well. Then overall, NOT make a recommendation of any one of the oils, because that would differ from person to person based upon their particular priorities and perspectives. For example, someone who rides in extremely cold weather will have a priority to find the best oil for cold flow. Others, in Arizona, will want an oil in hot weather which will not foam and provide lubrication in extremely hot, dry weather. Others along the coastlines may be concerned about the affects of an salty atmosphere affecting oil longevity and so on and on. This is one of reasons for differing opinions.
Probably one of the things that I personally wish is to evaluate differing oils (but not so many as the article did) of the slipperiness of the oils under varying conditions. For example, I have heard that synthetics are far slipperier than conventional oils - not so much just after the oil change, but a lot after some miles are on them. Another example is that I have been told by oil engineers that the synthetics provide MUCH better lubrication before engine warm-up which is when most engine wear happens - at start-up and just after.
I used to work for a large corporation (which I am sure you have heard of) and our local plant (around 2,000 employees) used literally thousands of gallons of hydraulic oil each year. that company's choice was Mobil/Exxon which, I am sure, was largely chosen for cost/pricing reasons.
Another issue I heard was that of all the synthetics, Mobil 1 was the ONLY pure synthetic. The oil engineer who told me this stated that all the others in some form still had a regular oil base. True? I don't really know.
Years ago, I was told by an Amsoil rep, that he actually saw his car engine temperature gage go down after changing over to Amsoil! The problem with that logic was the the engine temperature gage is controlled by WATER temperature, and THAT is controlled by the thermostat. Even if the oil DID have the affect of producing less friction (thus less friction and less heat), the thermostat would simply have closed a little further to compensate and keep the engine at the desired constant temperature.
Finally, after all this, I would like to have seen the article say "under these conditions" such and such oil appears to be better, but "under these other conditions" this oil would be better.
Once people are shown HOW to sort through all that data then, and only then, can they make an "informed" decision based upon their own particular circumstances.
