MotorWeek. zinc and phosphorus in motor oil
« on: June 22, 2011, 10:09:16 am »
[size=0pt]The amount of zinc and phosphorus in motor oil was reduced even further with the latest API "SN" standard. Is there still enough zinc and phosphorus to protect engines from excessive wear? How about older engines, newly rebuilt engines, or engines with flat tappets? Should car enthusiasts look for ancient bottles of motor oil at estate sales? MotorWeek's master technician Pat Goss provides the answers in this four minute video:[/size]

Cheers, good stuff.
 
I've been running my engines on diesel engine oil for about 10 years now. They have higher zinc content than normal motor oil, and also has high detergent- the engine is absolutely clean after 3 oil changes... I mean the aluminium inside the head is silver instead of the ugly brownish color.
The problem with zinc with a newer gas cars is when the zinc passes the combustion chamber it clogs the cat and the o2-sensor.
No really a problem though, as if your engine is healthy, blow-by should be minimal, and o2 sensors are cheap...
