There  are only a couple of Mobil 1 oils having sufficient ZDP levels for 
our  
flat tappet engines.  10W30 is NOT one of them.

I'm comfortable using the Mobil 1 High Mileage 10W-30 SL oil--the  
phosphorus level is 900 and the zinc compounds are 1000.  But I bought  several 
changes worth at Walmart and Advance Auto because it was reported here  on VV 
that the high mileage oil was being phased out.  I'll cross this flat  tappet 
oil bridge again when I run out of what I've got.
