Inadvertently got in an argument...

Too many engineers think because they are an engineer in one thing that they know all about everything. The good engineers know what they kno and are willing to learn what they don’t. For the former engineer they will be the first one to tell you they are an engineer to which one of the best responses is to say really? What kind of train do you drive?

You are correct though DOT 3/4/5.1 are all glycol based DOT 5 is silicon based and not compatible as you know. And for boiling point concerns 5.1 can go in 3 or 4 but the reverse is not true, not that it will instantly fail it just a boiling point concern. Then there gets the really technical as 5.1 viscosity is thinner (probably not noticeable by foot but by a brake lever it is) and then you have higher boiling point racing DOT 4’s that can have even higher boiling points than 5.1. But for your argument sake you are correct.

I think a lot of these guys try to impress or scare you when they spout out "Imma engineer". Who cares? I didn't ask you if you're an engineer. In fact, I didn't ask anything. You started telling me what I "need" to do and buy when I already "know" what I need to do and buy.

Luckily for me, my parents didn't raise no fool. I know how to read and know to research to get information. To me, that's part of the fun, plus you get to learn something along the way.

Now I do believe (from a YouTube video I watched) that 370's with the base brakes such as I have, the lid to the brake reservoir should say DOT 3, and that the Sport and Nismo should say DOT 4. I don't know if that's true or not. Could be.

Either way, since I am upgrading the entire brake system on my base 370, I wanted to just go with a little extra headroom with the brake fluid. My thinking is that the thinner viscosity of the 5.1 will be better for the ABS pump/valves, and that the slightly higher boiling point is just another little bit of safety headroom, just because why not?!

Will I ever need any of that headroom? Most likely not, but it's there just in case, and it didn't really cost much more than the regular DOT 4 stuff.

So in short, yes...

I is an engineer.

Got degree's in welding and mechanical.

Plus criminal justice.

I don't play one on tv nor did I stay at a Holiday Inn Express last night.

Some engineers just suck. They have no personality. When in college. They are taught analytical thinking. Most don't take any social classes to help them in public. So they have a hard time being with someone who is not an engineer. Most read something in a book, so then it's the gospel. Even if it's wrong.

And they think they're right all the time.

Most have no hands on experience. They can't tell the difference between a metric crescent wrench and a standard crescent wrench.

Old saying from the Swinburne Institute of Technology engineering school ...

Last week I couldn't spell engineer, now I is one !

Come on! You must know close to everything... just look at that rep power #!!!

I'm one of those idiots that know more then most about everything. But there are still some things I know nothing about. Like women.

You probably know more about one topic than I know about all... and Im not being sarcastic! Similar to what someone said above, life experience trumps book smarts.
