I think you need at least 3 more "reserved" posts.

Damn, thought we were going to talk about heat transfer. Ah...memories of a class from hell, that somehow I still pulled of an A for taking an extra final exam. Classmates laughed at me, but I got the A and they got the B and C.

Classmates laughed at me, but I got the A and they got the B and C. Heat Transfer has been very good to me. After a student internship where I was doing aero, I ended up in a combustion group where our main concern was heat transfer. And that experience led to my noise engineering job. The combination of the two experiences led to my current emissions engineering job.

The combination of the two experiences led to my current emissions engineering job. The Heat Transfer class I took eons ago was known to encourage students to drop out. I recall over-hearing a conversation where the TA notified the professor that about 1/3 of the enrolled students already dropped the class. The prof's response (while chuckling) was to work on the remaining 2/3. Hindsight, yeah, the class was tough and the rumours didn't help much but in the end the prof was quite fair. At the end of the class I think I had a C and the extra final exam was optional where the stakes were the final exam score would replace the end of class score. Scored an 80, the threshold for an A. Told my friends that this extra final exam was easier than the regular exams. Oh well!

Look the equations up in the book, plug them into the computer, see what happens, and then figure out why the numbers came out like they did. Really, heat transfer is simple. Heat moves from hot to cold. That's it. Engineering is funny that way.

Do we have a All VT Hall of Fame? If not, there should be a committee just for that.

Wolfgang , I think I am going on a little bit of a hiatus. I am a plant, and I need watering.

I know I'll be ignored but I had a genuine oil post to add.
I recently read about a teen who saved $ to buy a used car, took his dad with him to the dealership. Cute car, no body rust, about 125k miles, seemed to be good.
They were about 3/4 of the way home when the engine started knocking. It was a Saturday afternoon and they got the car home and called the dealership at some point. The dealership told them to bring the car in Monday. For whatever reason on Monday when they called the dealership told them later in the week and in the meantime they had a mechanic come check out the car.
Apparently to hide the engine knock the dealership used a higher viscosity oil to get the car sold. The car ends up being undriveable and needs thousand$ in repairs. The dealership says "Whoop, not our issue" and leaves the kid and his parents to deal.
This all would've been avoided had they taken the car for a test drive over to their local mechanic for a quick check -OR- even to the nearest Auto Zone where they could've hooked up the computer to read the codes. Apparently the codes showing up were ALL over the place and if they would've done this (per volleydad) they could've avoided this issue.
There you go, my random contribution to oil viscosity talk that wasn't supposed to be interesting but has real life implications. I am prepared to be ignored.

Oil doesn't have anything to do with "engine knock", so I'm thinking this is probably a folktale.
(OK, so thinking it over, it does depend on what is actually happening. "Engine knock" is generally a combustion timing problem, which likely doesn't have anything to do with the oil, unless your valves are hydraulic and operated by oil pressure. However, engines can have "rod knock", which sometimes can be temporarily quieted by increased oil pressure. A thicker oil can increase the oil pressure, at least when the oil is cold.)
(I'm still suspecting this is a folktale, though.)

"Engine knock" is generally a combustion timing problem, which likely doesn't have anything to do with the oil, unless your valves are hydraulic and operated by oil pressure. However, engines with connecting rods can have "rod knock", which sometimes can be temporarily quieted by increased oil pressure. A thicker oil can increase the oil pressure, at least when the oil is cold.) (I'm still suspecting this is a folktale, though.) I won't dispute you, just reporting what was written. The dealership was specifically mentioned by name and allegedly the mechanic told them that they used a more viscous oil to subdue the knocking noise during the buying process. I went to dig up the original post to verify what was said and it's showing n/a on the book of faces so perhaps someone else disputed the claim and the folk tale was found to be false. If so I have egg on my face … Someone on this post also said "Dealerships give you three days to return a car" and if that's the case then all of this is bologna! And now I find I have potentially added nothing of value. It is true that you can't believe the internet.

"Dealerships give you three days to return a car" That's potentially also a folktale. Depends on local law. Some states have laws mandating a "cooling off period" and other states say that once you sign the contract, it's done. I expect that if someone sold you a car that they *knew* was defective while specifically and deliberately hiding the defect from you, you would have a pretty solid court case.

Speaking of defective cars, last April ago some young lady went into a Mercedes dealership I think in Xi'An, central China. Dealership smooth talked her into taking a loan out even though she was planning on paying by cash. Noticed oil was leaking even before she took possession of the vehicle. Brought it in several times to the dealership and they couldn't fix it and offered to change the engine. news.cgtn.com/news/3d3d774e3545444d34457a6333566d54/index.htmlLuckily justice sided with the customer and forced the dealership to refund her money. Also had to investigate whether the car had undisclosed problems, and although not mentioned in this article, the gov't looked into coerced loan even though Mercedes said they do not have a loan program offered through the dealership. And naturally, Mercedes reputation took a hit even though it was a local dealer swindling the customer. There is a happy ending...Mercedes apologized to the customer, offered her a new car free of charge (I think) and a trip to their HQ.
