Anyone got a copy of SAE Technical Paper 2003-01-3119?

I'm curious as to WHY wear decreases as oil ages, but I'm also cheap. [ December 27, 2003, 10:13 AM: Message edited by: Roger ]

This is the name of the paper. Are you sure you have the right ##??? "Antiwear Performance of Low Phosphorus Engine Oils on Tappet Inserts in Motored Sliding Valvetrain Test"

That's the one Al. I got the number from the Synthetic Oil Life Study web site. It matches the paper name and number listed on the sae.org page for ordering SAE Papers. http://www.sae.org/servlets/productDetail?PROD_TYP=PAPER&PROD_CD=2003-01-3119 Even though it is only 2 month's old, I thought I'd check around and see if anyone's got a synopsis of it. You've mentioned buying those papers in the past. Are they worth it? I mean $12 won't break me. [ December 27, 2003, 11:28 AM: Message edited by: Roger ]

his one seems to fit better: SAE Document This paper compares 5W-30 oil with 20W-50 oil in terms of Urban/mixed/highway miles. It compares the oils at 800 KM and 15,000KM . The gains in fuel economy drop as the oil ages but the 5W-30 oil increases its advantage over the 20W-50 oil at the 15,000 km mark. I just scanned the report. I'll post more later.
