Abstract
A process and method for manufacturing an improved engine oil comprising mixing ferric fluoride with ZDDP to form an additive mixture, heating the additive mixture to at least 125° C. for at least 4 hours to produce a pre-reacted mixture, and adding the pre-reacted mixture to a fully formulated engine oil not containing ZDDP. Also disclosed is an engine oil prepared by a process comprising mixing catalyst with ZDDP to form an additive mixture, heating the additive mixture to about 60° C. to produce a pre-reacted additive mixture, and adding the pre-heated additive mixture to a fully formulated engine oil not containing ZDDP.
Claims20
A method for improving engine oil comprising:
- mixing a catalyst with zinc dialkyldithiophosphate (ZDDP) to form an additive mixture, wherein said catalyst is a metal fluoride;
- heating the additive mixture to produce a pre-reacted additive mixture;
- and
- adding the pre-reacted additive mixture to engine oil that does not already include ZDDP.
