Holy cow everyone !! (fitting for Wyoming,,, although I was never in any of those businesses,,,) What outstanding replies !!
I would like to acknowledge each person, but for the sake of efficiency I'll just make a general reply to all.
And maybe I need to first make these few comments: Please accept the fact that I am not here to frustrate or annoy anyone. When I deserve to be scolded, I will accept it with due respect. Forgive me if my posts get too long or unnecessarily detailed. Yes, I could have included such things as dynamic viscosity and the resultant bearing heat generated, the critical importance of oil film strength, dry starts and the industry proven resultant wear, and on and on. I just didn't feel it was necessary for the purpose my my question. I still use the old-fashioned laptop for my interface with the amazing world wide web, hence the ease of using quotes, etc. for clarity quite convenient. I'm just an old retired guy that still values learning things. I am willing to share with you things that I am discovering along the way. I have always valued quality motor oil and filters, even to the point of overkill. I am very impressed with the broad spectrum of fantastic knowledge and experience found here on BITOG.
So, by posting my question in this "new" thread, it has generated outstanding responses from many people that otherwise would not have seen my questions/comments on other threads with similar subject matter. Thank you for that privilege.
At this point I am finding it absolutely intriguing that so many people's real world experience is totally verifying the overall validity of using a motor oil that falls within approximately 9 to 12 cSt kinematic viscosity. -the properties of a typical 30wt oil at 100 degrees C. -maybe overkill, but likely good insurance.
And to that I add several other properties, in some cases not critical, but certainly pertaining to overall high quality.
Like purity of the synthetic base stock oil used, the high importance of a quality balanced total additive package, and the very high importance of the seldom mentioned, often forgotten, or just plain unaware actual factual provable film strength of the finished oil. -something that so far I have only found published from one source, a mechanical engineer, not oil company data.
I really like the concept of using whatever makes a person feel cozy at night. That is very profound advice. Especially given that there is a certain amount of flexibility in actual product used, just as long as the OCI's are always respected as being critically important.
I have a rather profound statement I read somewhere years ago, regarding the undeniable basic facts of how proper lubrication between any two moving metal parts can make wear impossible. If there is any interest, I will see if I can recall it.
Cheers everyone. Thank you for the continuing interest. Have a quality day !!
