Abstract
The combination of a fuel-soluble succinimide detergent/dispersant, a fuel-soluble liquid carrier or induction aid therefor, and a fuel-soluble cyclopentadienyl manganese tricarbonyl compound can sharply reduce the formation or accumulation of engine deposits such as intake valve deposits in internal combustion engines. In fact, such compositions can function synergistically whereby the effectiveness of a highly effective succinimide-based deposit control additive can be improved by the addition thereto of the manganese compound, the latter not known to be a substance that reduces deposits.
