Gasoline engine black sludge - occurrence, causes & testing
Abstract
1. Gasoline engine sludge is a major worldwide problem 2. U.S. and European sludge have similarities 3. Stop-go driving and longer oil drains make the problem worse 4. Fuel is a major influencing factor 5. Increased use of cracked components may be cause 6. Sludge can be peproduced in controlled field tests 7. Daimler benz M102E and ford PV-2 (VE) tests have been developed to overcome problem by higher oil quality 8. The M102E and PV-2 respond in a similar way to increased dispersancy 9. High dispersant ocp viscosity modifiers appear to have unique adbantage in both tests
