I'll offer the apology for seeming that I was on a rant; not my intent. However, ...
Are you not the one that specifically stated you had a Harley, and in fact was your question not specific to a TC Harley? What did you expect me to point my answer towards? You are also the one that mentioned PAO products (Mobil 1 and Amsoil) and HDEO produts (JT-8, Delvac, Rotella, etc), are you not? Seems to me you were questioning the applicability of dino HDEOs, compared to the performance you might expect from the high-dollar PAOs. Did I mis-enterpret your statements and question?
Then you asked this, referring to dino HDEOs: "...
but what's the opinions out there for use in the twin cams with their high temps?" and I gave a specific example of how an HDEO is designed for high temps in a diesel, and how those temps are comparable to a TC engine.
Then you stated this: "
Thanks for any feedback." Gosh, I presumed this meant
all manners of contribution were acceptable; perhaps I misunderstood.
And then this from you: "
The whole point of the post was to try to get opinions on the HDEO oil’s listed". Ummmm - isn't that what you got? I'm sorry if I wasn't specific enough. Delvac - great stuff. Rotella - excellent. Mystik JT8 - very worthy. I consider them all fine quality HDEO products.
You also said this: "
I've used syn3, Mobil 1 15w40 and currently Amsoil 20w50" and this: "
My OCI is 3000 to 3500 normally."
So I stated this: "
Geeze - most guys dump the oil out of their Harley LONG before it's used up anyway, regardless of brand or grade." (I do belive you qualify as an example.)
Exactly where is it that you thought I got off topic?
I'll again offer the peace pipe for my tone. But, golly, my answers were spot on, and I don't know how you saw it otherwise.
P.S. - the amount of time one spends in the seat has nothing to do with the relationship of the engine to it's lubricant. My wife accumulates more driving miles than do I at times, due to the nature of her job. Does that make her more "lubricant savy"? Hardly!
Welcome to the site, BTW.
