Obectivist take on motor oil

[crenca]

I know there are more than a few  car guys & gear heads around here.  I found this recently (you may already be aware):

I can not vouch for the accuracy of his results, but his methodology appears to be valid.  I know many of you will continue to taste, feel and fart on your motor oil in attempt to lift a thousand veils of viscosity and the like, but some of us will might find his method/results helpful.

This guy needs an editor and to put that info in a spreadsheet or something.

[cjf]

Even for a motorhead like myself, that is a brutal read

[Ralf11]

part of it is about the need for Zinc, aka ZDDP in older motors - not new

 

some of the rest is std. tribology, which can be found elsewhere online with nice diagrams

 

agreed the guy lacks... um... poise

[GregWormald]

Poor presentation plus HUGE diatribe against "high zinc, low wear" fantasies.

However, really good data once you get past the "introduction".

Now I know why Porsche recommends Mobil 1.

new Porsche, yes

 

old air cooled ones need ZDDP such as Brad Penn, Joe Gibbs*, certain Delo or Rotella oils

 

Pooschey now sells their own oils too - guess how much it costs????

So, you're telling me the purchase price isn't the end of high expenses when buying my Singer?  Damn...

 

 

 

 

 

 

 

*not really buying a Singer

Yep, that site is in desperate need of formatting.  

 

Section 28 is useful to me because I realized recently that all three of my vehicles call for 0-20W oil.  Turns out Mobil 1 Extended Performance is the 2nd best oil of this weight he has tested which is a good thing as it has been I reached for the last few cycles....

get a ruf

 

 

it will kill your Singer dreams even tho it has the fugly bumpers

 

or... do what I did:  DIY as light and powerful as you can [1] afford, [2] think prudent

 

I just wish I had a '72 unit body, not the '73...

I have also found that the audio reproduction via my car's audio system is waaaay better when I install Mobil 1 in the crankcase.

I will probably not be able to afford a Ruf either.

so the doctor part is not cosmetic surgery...

 

just get a '74 and debumperize it to look like an early car; then hotrod the motor and fix up the suspension

[SuperRoo]

My AWD turbo boxer sounds great when running plain old 10w30 dino oil. I did upgrade some of the cables.

[Speed Racer]

I use Red Line 40wt Racing Oil in my race car. It has an air-cooled 3.6L normally aspirated engine in it out of a '93 964.

[AudioDoctor]

Porsche recommends Mobil 1 in my GT4, but I don't think it is 10w30 and I am not going to go look at the box in the garage right now.  

 

edit: Went to my Rennlist history.   Mobil 1 5W-50

ha, no I am not a plastic surgeon.  Pediatric Trauma/Critical Care

[Ralf11]

I cannot imagine the insurance rates for that...

For the GT4 or my Practice?

[elcorso]

A few years ago I saw a Russian truck that used beaver oil in the power steering. Very difficult to find in the Rainforest. Maybe these cars had constipation

hahaha, crazy ass russians!

Maybe not, it last ten times than regular power steering oil and I guess that there are a lot of beavers in Russia.

 

It's like 6H30π tube (super tube).  Now in use in HE music gear.

The tube was designed to withstand atomic radiation in case of war, for the original Soviet MIG planes !

 

Sorry for the out of thread...

Maybe, maybe not!  lol

I meant the practice, but a GT4 can be costly.  A friend let me drive his GT-3 on Mulholland drive once and I drove it like a little old lady.  He drove it up before that, and I thought he was going to clip one of the elderly billionaires going down the hill to check his mail...

[Ralf11]

speaking of the thread title "Objectivist"...

 

the damage to older car motors form less ZDDP in the oil was not predicted based on mechanistic analysis - it was discovered after valve train parts started failing

 

so, very much like the epidemiological type analysis done first in the London sewer example, and common today when a cancer cluster is spotted
