First oil change

[JET_83]

Touc

When you have 2 guys with 150-200k+ miles on their engine, one of which changed oil every 3k miles and the other who changed theirs every 8k miles… who was more right in the end?

(Talks of financial responsibility aside because that’s not what the original thread was about)

Touche but can you confirm the accuracy of that?

How do you know it’s quite accurate? It’s a chip so it can malfunction

Proof of this can be seen at the bottom of any bag of chips ... Open your eyes !

Not without changing the oil and guessing at its health just by looking at it.

HAHAHA - observation. I do have pretty good powers of observation. And a background in science, automotive, and years in networking, network security, switches, routers, did board level repairs on Compaq notebooks in the 90s, was authorized for Compaq warranty work.......... designed and spec'd the computer interface systems for the Compressor Controls Corp Series IV turbo compressor control systems.
(all that is a long way of saying - I get computer stuff)
Chips fail in a way that won't cause the calculations to be off........

Without going into long drawn-out details, my degree is in automotive.

So I decided to take a look at the new oil I have out in the garage, and it seems pretty thin! Way thinner than the oil I used on my Nissan. Looks like I'm going to have to call Pennzoil and complain that I got used oil.

Better get on that ?

Ask them why there’s deposits at the bottom of the quarts too

Can't you tell me? I've heard you can tell me everything about my oil just from looking at it.

Imagine if he'd seen the oil coming out of my diesel tractors years ago........ and your HANDS were black if you got it on you.

Anyway, as far as looking dark, like we said, some looks darker right out of the bottle, but there are other things that can make it look dark, none of them necessarily bad:

a) heat cycles,
b) contaminants,
c) the presence of additives that cause the oil to darken during normal use.

NAPA, Toyota, AMSOIL and other companies have info on oil being dark. As NAPA says "it's not time to panic".

This is from AMSOIL -

While heat cycles cause oil to darken, soot causes oil to turn black. Most people associate soot with diesel engines, but gasoline engines can produce soot as well, particularly modern gasoline-direct-injection engines.

Soot is a byproduct of incomplete combustion. Since soot particles are less than one micron in size, they typically don’t cause engine wear. For comparison, a human hair is roughly 70 microns in diameter.

IT specialist? lol

I taught a class in Eugene, OR for Symantec corporate products in 2000. Head of network security for an agency of the state of Iowa. So is that a problem?

As for cars, I now run a restoration shop. My degree is in automotive, state winner Plymouth Troubleshooting contest, went to nationals. 4.0 GPA in college. Skipped the first two HS auto classes because by that time I had my own shop, so I went right to the third and top class in HS.
Tested out of college math as I'd already taken it in HS.
Apparently Jeep thought I was ok back in the 80s because I got a call from Iowa's largest Jeep dealership offering me their service manager position. We had never even met. They tried to hire me away from another shop.
Do you want more automotive background? Ok - my work has been on several AMO international gold winners, one of my cars is a 3 time gold winner and I have people from all over the country send me parts for restoration.

Your turn.................

Then why turn down the job?

Apparently you've never been in-demand or you'd know. There are tons of reasons a skilled candidate turns down offers.

OP, that’s the great thing about America. You’re free to do whatever you want. Change your oil once a week for all I care. That doesn’t mean everyone else is wrong. You do you & let us do us.

 

[Shifu]

I’m waiting till the computer tells me to change it. So far 7200 miles and 15% oil life.
