I like pictures like this. It’s a reminder for some that the automobile is the most complicated and technology packed object they interact with... by a wide margin. 

I suspect we will see a statistical improvement with each level. Will there still be injuries and deaths? Yes, of course, but less than what we have now. The trends of automobile legislation are designed to prevent injuries and deaths, so it would be no surprise if manual driving were eventually outlawed. My only hope…

It will take a while, but it’s inevitable.  Once all the kinks are worked out, prices will be cheaper.  Then again, There is even a chance that car ownership will not be required anymore, and you only call a car when you need a ride, like a ride share system.  I seriously don’t think it’s a matter of if, but a matter…

I change my oil every 10,000 miles (unless I do a track day). Every car I own is over 200k miles.

Oxidation and acidification are the main reasons you change your oil

I like this channel, but he lacks a lot of the statistical methods required to really detect differences in some of the things he tests. When you are trying to detect a very minor difference you either need really expensive equipment or a large sample size to provide the statistical significance required. 

People honk at me for going to fast in the snow, yet I don’t ever have any trouble stopping at intersections. I wonder why that is.

Doesn’t seem like it would be that big of a deal to find someone to let him use one of these:

Your friend is right. Besides it’s better to actually measure the pressure drop across the filter, and replace it when needed, instead of guessing and wasting money. For example, the pressure drop across the filter of my Fiesta didn’t get to 2kPa until 150,000 miles. I installed this in my car, it’s saved me more…

My filter didn’t really get clogged until 150k miles. 

knowing that you’ve added both power and efficiency to your car without turning a single tool. 

Except that i’m just buying the part in both cases, not having them install it. So, it’s the same warranty. It’s also from ford parts online, not the dealer desk.

I’ve been IN the industry on the engineering side for 10 years.  I guess I’m just optimistic and keep thinking each time was a fluke. 

I just can’t anymore. I have never had a positive experience at a dealership. Taken my cars for warranty work and they can’t figure out whats wrong until I go back in the shop and show them it’s a bad tie rod, or I open the hood and see bolts left loose.

The latest three issues I’ve had: A bill for service (I hurt my…

All of this is splitting hairs, and is really only of concern if you are developing an engine. This is why we auto engineers spend billions developing a car. So you don’t have to worry about it. Just don’t beat your car senseless, and carry on. 

Laws of physics are the same. What is tested during development is different. Oil is a SUPER complicated chemistry fluster cuck, and every maker has a slightly different specification of chemical mixtures for anti-wear, anti-foaming, anti-oxidation, anti-moisture, etc. etc. It all boils down to splitting hairs though.…

It’s too bad that chart doesn’t have 75w-90 gear oil (instead of just the sae 140 gear oil). Most people are incredulous to learn that gear oil has very similar viscosity as motor oil, it’s just a different type of oil. SAE weights can be confusing.

Idle bump has a LOT to do with many things.  Catalyst light off is a big one. You should see some of the retarded timing along with high MAP’s to light off the cat.  

Also, get that guy to google who thought the SAE weight of an oil was the measure of viscosity.  As if.
