I'm sending the link of this conversation thread to the mechanic and if there is a chance that I'll be running with a dry pump, I'll ensure it is looked after, even if I have to hook up a battery booster, disable engine start somehow, and turn it over until we need to worry about the starter. Call me anal, call me nuts, call me overboard, but the matter of oil starvation is of course something of great concern and this is not my first "after a whole year" oil change and I am thinking of as many factors as I can in pursuit of a great cleansing.
"Still, I am wondering what your hypothesis is on the oil that is blown out with the air. Do you think it will have more contaminants in it that the other oil?"
I distinctly recall that UOA samples should NOT be taken from the first or last quart or so. Surely I am not the only one to recall that, and I am very happy I'm not the only one to second-guess it: The oil had been circulating around and around and I don't see why the last bit should have different metal counts or the like, relative to mid-stream. Thus I want to test the how's and why's of it.
"I don't mean to be rude"
I know, and I thank you again. You are not rude and I shrug off those that are (to the best of my ability) There are over so many thousands on BITOG, the few that poke fun at me are not indicative of the many that want to see my results. FWIW the mechanic-friend used to poke fun at me for buying $12 a quart oil, shipped up from the US, keeping it in for a year because of a 1 micron absolute / 0.5 micron nominal filter
"but I just dont see that you can learn much from the analysis of the "blown" oil."
Has anyone done this before to see if they are same, similar, have some interesting differences, or are very different? If so it should have been posted on BITOG long ago. I have the nasty habit of volunteering the be the Guinea Pig. Thomas Edison, the Wright brothers, and those that first tried going into space or the moon, were scoffed at. I have no plans to be next to Edison in the history books, just trying to do what I can in my little corner of the BITOG world
"I think you might learn more if you got an analysis of the BG flush."
That will be done also! I have chosen to take the mechanic-friend's advice and give BG's methods a try and give them the benefit of the doubt. They have done research and know what can go wrong. Plus the mechanic disbelieves everything at first and wants proof. He second-guessed and debated everything the teachers said in mechanic school and as a result, remembers the how's and why's and what-if's behind the course material. He caused the teachers great pain...probably the greatest when they gave him the award for a great 'final' at the end of the course. I trust him, he trusts BG, he suggested I try BG, I am trying and trusting BG.
Here is his plan / the plan: Drain all old oil into a jug. Then call in the 'air force' and do the 'blowing job' and keep that seperate for a test. Fill will plainish dead-dino oil, add the BG stuff. Run as needed, then drain with another set of samples, and another forced-air pushing of the residual oil (yet another bottle). Then fill with Redline. If the numbers come back as a problem, switch to GC for our Southern Manitoba winters. Now THAT is where I worry about dry start-ups.
Anything else to discuss?
Best wishes to all
