Anti-wear additives such as zinc and phosphorus are limited by lawmakers because they damage catalytic converters on engines with high oil consumpion.

Kinda putting the cart before the horse, if you ask me. Any diesel grade oil, motorcycle oil or any oil marked 'Racing' does not have these limits applied to them.

Diesel grade oils tend to have more detergent additives in them, plus more acid neutralizers such as boron, calcium and magnesium to cope with the demads in such engines.

So you are saying that the diesel oil would provide a longer life for the engine overall, than say if I ran Mobil 1 the life of the engine?

Not necesarily, but it can't hurt, is what I'm trying to say. I haven't seen a good comparative analysis of major oil brands since 2003. However, I had read a tech bulliten published by the Porche Car Club of America which cast doubt on the ability of modern gasoline engine oils to protect their beloved air-cooled pancake-sixes. A lot of 911 owners run Rotella 15-40 (non-synth) in their vehicles. a 911 holds a little over two gallons and most owners like to change often.

Mobil 1 stacks up good, if you like it, there's no need to switch.
