Engine friction basics begin with a simple fact: an engine’s moving parts resist one another as they work. From piston rings sliding against cylinder walls to bearings supporting the crankshaft, this contact is necessary for operation but can reduce efficiency and generate heat. Engine oil helps control that resistance by forming a protective film between … Read more

Engine pressure is essential to how an engine produces power, circulates oil, and manages air and fuel. Understanding engine pressure basics helps explain why readings vary during operation—and why an abnormal reading can point to a developing mechanical problem. Compression, oil, intake, and fuel pressures each serve a different purpose, so no single reading tells … Read more
The all wheel drive warning light tells you that the system sending power to all four wheels has a problem or has temporarily limited its operation.
