ABSTRACT:
The present invention relates to a clean gear boron-free gear additive employing a boron-free ashless dispersant, a sulfur source and a phosphorus source. More particularly, the preferred boron-free ashless dispersant is a hydrocarbyl succinimide. This additive composition when blended with a suitable base oil meets MT-1 and MIL-PRF-2105E requirements without the need for boron. MT-1 is a requirement for a clean gear manual transmission oil. MIL-PRF-2105E is a requirement for a rear axle oil.
