Here it is fellas

Blackstone wrote: " Thanks for the note that this oil was from 1985. Back then copper was a common additive in the oil so the 97 ppm here isn't a problem at brass/bronze parts. Universal averages show typical wear levels for this type of engine after 4500 miles on the oil. This oil was run just 3,000 miles, so we're happy to see all wear readings close to or below averages. This engine was started right before the sample was taken, so that explains the fuel we found. The TBN was stong at 5.0, so lots of additive was left. 1.0 is too low. It looks like this old oil is doing just fine. Nice report.

JUST like I thought it would turn out!

You can clearly see how SE/SF oils sacrificed detergency for Zn/P and viscosity spread (as mola has said), although, even with low detergency, the oil still held good TBN.

VERY interesting about copper being an additive in old oils - I've never heard this before. I know copper is used in 'Restore', but I didn't know it was a regular oil additve in OTC oils!

Man, with a TBN of 5, you could probably run this 5-6k miles and be just fine, like many probably did back in the day! I've always wondered what the oil looked like that my Godfather would have run in his 1976 Gremlin that kept it going for 12 years. This, and the PS article have let that happen!

Thank-you soooo much!

I don't comment in this section much, however I must do so here. It looks like there is nothing new under the sun in engine oils, only different ways to get there.. Copper by the way has outstanding lubrication properties.. I use copper based anti seize in place of grease/oil in some applications, and it outperforms expensive, top end stuff either grease, or oil most of the time.

Calcium 428? Don't think I'll be trying this in my car, but thanks for playing guinea pig for our entertainment.

The magnesium level of 883 is decent though...

Okay, I'll reply as I did in your other thread.
I told ya'll that this oil would do just fine in a moderate performance engine in typical use, and it did.
Edge and Ultra?
For what?
