Compositions and methods are disclosed for reducing combustion chamber deposits (CCD) and/or intake valve deposits (IVD) in spark ignition internal combustion engines. A succinic acid derivative (SAD) of this invention or a mixture with at least one additional component of this invention is added to a liquid hydrocarbon or liquid hydrocarbon-oxygenate gasoline each in an amount of about 0.0005&#x2013;0.5 wt % of the gasoline. Preferably the gasoline is unleaded. The preferred additional components include polyethers (PE), polyolefin butyrolactam derivatives (BLD), butyrolactam alkoxylates (BLA), tridecanol alkoxylate derivatives (TAD) and polyisobutylene amine (PIBA).

Compositions and methods are disclosed for reducing combustion chamber deposits (CCD) and/or intake valve deposits (IVD) in spark ignition internal combustion engines. A butyrolactam alkoxylate (BLA) and/or a butyrolactam derivative (BLD) of this invention or a mixture with at least one additional compound of this invention is added to a liquid hydrocarbon or liquid hydrocarbon-oxygenate gasoline each in an amount of about 0.0005-0.5 wt % of the gasoline. Preferably the gasoline is unleaded. The preferred additional components include polyethers (PE) and polyisobutylene amine (PIBA).

The invention relates to fuel additive compositions for internal combustion engines and to fuels that contain the corresponding additives for internal combustion engines. The inventive fuel additive compositions for internal combustion engines have an excellent performance in keeping the inlet system clean and improved viscosity properties, especially at low temperatures.
