Boosted High Horsepower Motor Oil?

[Grape]

anything diesel related will have tons of detergent which causes detonation. even rotella had the zinc pulled out in march of 07, the same time all the exhaust filters showed up on production diesel trucks. mobil 1 motorcycle 4t full synthetic has over 1600 ppm zinc and is readily available at oriellys or autozone and is about $10/qt.

10/40, there is also a V-twin version of the same oil which is a 20/50 and has over 1750 ppm zinc.

So VR1 has no zinc in it anymore, am I reading this correct Grape?

vr1 does, but there is a huge warning on it to not be used in street cars with catalytic converters.

Ok, I've been using it in my sprint that's got a solid flat tappet cam and I was worried about wiping it out.
