ABSTRACT:
Phosphorus-free, low ash and light ash motor oils containing no metal DTP's, halogens or hazardous substances are disclosed.

Additionally, light ash motor oils containing no metal DTP, halogens or hazardous substances are disclosed. The light ash formulations may be prepared either as a lubricating oil or as a concentrated additive for a lubricating oil. The use of both the oils and the concentrated additives results in superior price and performance qualities compared to the leading commercial brands.
