Crankcase dilution occurs when the fuel oil from the engine gets into the lube oil of the engine. This can be caused by the walls being wetted due to the fuel condensing in the cylinder. If the engine is cold, or there is an excess amount of cooling around the cylinder, [ 1 ] the fuel oil will condense and have a higher chance to end up in the ...
Oil sludge or black sludge is a gel-like or semi-solid deposit inside an internal combustion engine, that can create a catastrophic buildup. It is often the result of contaminated engine oil and occurs when moisture and/or high heat is introduced to engine oil.
Motor oil, engine oil, or engine lubricant is any one of various substances used for the lubrication of internal combustion engines. They typically consist of base oils enhanced with various additives, particularly antiwear additives , detergents, dispersants , and, for multi-grade oils, viscosity index improvers .
The problem isn’t that cheaper oil will hurt your engine, ... But most modern engines don’t need new oil very often, with most cars requiring service every 5,000 to 7,500 miles. Rather than ...
The ILSAC GF-6 standard (released in 2020) also include a test for oil-related LSPI events in gasoline direct-injection engines based on a Ford 2.0 L four-cylinder Ecoboost engine. [9] API oil category SP, introduced in May 2020, was designed to provide protection against LSPI. [10]
The engine was affected by an oil sludge problem and premature timing chain tensioner failure. The oil sludge issue appears to have been caused by issues with the crankcase ventilation system, and while it affected a minority of engines, it could cause complete failure [ 1 ] In some cases, neglected maintenance aided in premature failure ...
Kia America, Inc. is recalling certain 2021-2023 Seltos and Soul vehicle due to potential problems with piston oil rings. Kia recalls more than 137,000 vehicles for engine issue: See affected ...
Particles in the oil can also cause serious problems with oil pressure. After oil flows through the engine, it returns to the oil pan, and can carry along a lot of debris. The debris can cause problems with the oil pickup screen and the oil pump itself. The holes in the oil pickup screen measure about 0.04 square inches (0.26 cm 2). [6]
