Abstract
Phosphorus-free, low ash and light ash motor oils containing no metal DTP's, halogens or hazardous substances are disclosed. The phosphorus-free, low ash formulations may be prepared either as a lubricating oil or as a concentrated additive for a lubricating oil. 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.
Claims14
A lubricating oil comprising:
- a. about 80% of a paraffinic base oil;
- b. about 1 to about 3% of a magnesium salt of an alkylated aryl sulfonic acid or calcium salt of benzene sulfonic acid;
- c. about 0.005% of a compounded silicone fluid;
- d. about 0.05 to 1.5% of 1H-Benzotriazole-1-Methanamine N,N-bis(2-Ethyl Hexyl)-Methyl;
- e. about 0.05 to about 0.15% of a 2,5-dimercapto-1,3,4-thiadiazole derivative;
- h. about 0.50% of a diethanolamine derivative;
- i. about 9 to about 10% of an ethylene-propylene copolymer;

A concentrated additive for a lubricating oil comprising:
- a. about 50% of a paraffinic base oil;
- b. about 1 to about 3% of a magnesium salt of alkylated aryl sulfonic acid or calcium salt of benzene sulfonic acid
- c. about 0.005% of a compounded silicone fluid;
- d. about 0.5 to 1.5% of 1H-Benzotriazole-1-methanamine-N,N-bis(2-ethyl hexyl)-methyl;
- e. about 0.5 to about 1.5% of a 2,5-dimercapto-1,3,4-thiadiazole derivative;
- h. about 3.0% of a diethanolamine derivative;
- i. about 9 to about 10% of an ethylene-propylene copolymer;
- j. about 2% of a dispersant selected from the group selected of a borated polyisobutenyl succinic anhydride, an amine compound with (polybutenyl) succinic anhydride, a polyethylene poly-, compound with (polybutenyl) succinic anhydride and combinations thereof;
- k. about 0.3% of a dialkyl fumerate/vinyl acetate copolymer;
- and
- l. about 0.5% of (tetrapropenyl)-butanedioic acid, monoester with 1,2-propanediol and (tetrapropenyl)-butanedioic acid wherein said the concentrated additive is absolutely free of ZDTP.
