Guess my TBN

[jimbrewer]

I want to do something different: Tell me what my TBN will be before I get the results. All you smarty-pants guys get to put it on the line instead of pontificating after the fact. Also, wisdom of crowds and all that:

My situation: 2012 Ford F150 3.7L. 5,075 on Motorcraft 5w-20 semi-synthetic. 90% short-haul (less than five mile) city driving, no hauling or trailing. Oil was changed in early September, 2012 (I'm a low-mileage driver, obviously). Its cold up here. I live in the southern rockies, but the car is garaged. I use no ethanol premium gas, if that makes a difference, and the OLM reads 33%. This is the first fill after factory fill.

To make it interesting, feel free to tell me what factors you rely on and which ones you do not. But don't waffle. Give me a TBN number.

Good luck.

What lab is doing your UOA?

3.5

4.+; presuming it's Blackstone.

Pointless exercise! There is no power in a WAG except occasionally when you guess right and can swell your ego out of sheer luck. More educational if you listed the TBN and the full UOA and then ask for wherefores and whys based on actual facts.

Its Blackstone. My guess is 1.8. Well see if there is a home court advantage. Sample should arrive Thursday, results a little afterwards. Quite a spread here, which surprises me a little so far.

No kibitzing without a number! A guy who has 3700 posts on this forum ought to have a pretty good idea how these things fall out.

P.S. The ego bolstering only works when you take an extreme position and it works. "0" is already taken, but we have numbers north of "4" still available.
