I’m honestly surprised auto manufacturers don’t make it more clear what type of oil should be in the car. I mean, I’ve been in a few conditions in the states down here (surprisingly only one state away from Arizona) where 5W was not adequate. Then again, most people don’t have the mental bandwidth to understand how to…

Ok, I left out my assumptions, I’ll give you that. In my mind, an acceptable design life of an engine is “long enough that by the time I need a new engine, the car is worth less than the repair.” Running your car cold isn’t going to change you from pass to fail. If literally every other component on my car is going to…

That moment when you realize that you didn’t pay for any of the furniture in your apartment because it was either a hand-me-down or found on the side of the road...

You have one jet to fly to your Bugatti so you can go on a road trip through the south of France. Then you have a second jet so you can fly from the end of your trip back home. The third jet is to pick up the first jet that you dropped off at the beginning of your trip. I can’t believe I had to explain that to…

I don’t doubt that an engine can seize in cold temperatures, but that could just as easily be related to dirty/old oil, pre-existing damage, or even just having temperature below the capability of the oil. Afterall, 5W oil is only rated to -22°F(ish). At that point, you need to be running 0W.

I’m not arguing anything close to an absolute. I’m literally saying that if your cold-start temperature is within the design criteria of the oil, then it’s within the design criteria of the engine and you have nothing to worry about under normal loading. In other words, the oil’s rated cold-start temperature defines…

To be fair, I thought you were responding to a comment I made where I went into a lot more detail than the one you actually responded to. Sorry about that.

Hijinks may include: missing nap time, complaining about change, driving too slowly, etc.

At what point did I say cars don’t need to be warmed up ever? I’m not saying that you can just run your engine without warming it up in any temperatures. I’m saying that oils are rated for cold-start temperatures and as long as you’re not outside of those cold-start temperatures there is zero reason to worry about…

At what point have I said anything about it being ok to abuse your engine at all? I’m saying that they design the engine to meet performance requirements under expected driving conditions in their predicted environments. Your engine has a finite life even if it operates at running temperature for 100% of that life.…

The models account for engine loading. It’s quite easy to add that detail nowadays actually. And no one is saying the “issue is eliminated.” I’m saying that the engine is designed to tolerate “the issue” at the maximum predicted oil viscosity and still maintain their specified minimum reliability/longevity targets. At…

No one’s claiming the new technology doesn’t adhere to the laws of physics. It’s that our thermal modeling of systems is substantially better at predicting how clearances between moving components change due to thermal expansion. Also included in those models are the changes in oil viscosity as the temperature…

As long as you’re using the appropriate oil for your climate, the oil will really never be so thick that it doesn’t get to where it really needs to be. Engines are designed with the range in oil viscosity in mind.

Nope. They’re your actions.

No, I’m saying that if my parents were both currently in the ICU, I’d be pretty stoked to be around good people too. Fault him for what you want from his presidency, but “smiling at an inauguration ceremony” is a bit of misplaced rage.

Be fair to dubya. With his parents’ recent health issues, today really is the best day he’s had all week.

Agreed. The automated dual-clutch transmissions are significantly better, but the traditional style autos are still just as bad as they’ve been for a couple decades at least. The Chrysler 200 I had most recently had just as bad a transmission as the Honda Accord I had in 1994.

Ok, on pharmaceuticals and medicine in general. Totally agree. I missed an entire industry, let alone a product.

Good point. I guess this just means that the NHTSA won’t force a recall, but not that there won’t be ongoing litigation as to Tesla’s responsibility.

Then that begs the question, “At what point are semi-automated systems safe enough to be sold to consumers.” This is one of very few products (none that I can think of) where anything other than unforeseeable misuse of said product or error by the end user is expected to result in the death of its users. The fact that…
