Motorvac's recently unveiled OilClean MOF 1000 uses the company's specialized detergent to flush-out sludge and contaminants that can build up in the engine and lubrication system components, including the oil galleys, valve train, oil pain, timing cover and oil pump. The unit works with spin-on and canister-style filter assemblies, and contains an air blast control to remove residual oil from the pan. One selling point for the machine's services include the fact that a more efficiently operating engine can help improve fuel efficiency.
