The designation 5W-20 refers to the viscosity of engine oil and how it flows at different temperatures. The “5W” indicates the oil’s flow in cold temperatures (the “W” stands for winter), meaning it remains thin
Engine oil viscosity is the measure of how thick or thin engine oil is and how easily it flows at different temperatures. Lower-viscosity oils flow faster in cold conditions to protect the engine during startup,
An SAE viscosity chart shows the standardized thickness ratings for engine oils at different temperatures, helping you choose the right oil for your vehicle. The “W” number (e.g., 5W) indicates how the oil flows in
The Quick Verdict: White sludge on Oil Cap(often looking like “mayonnaise”) is an emulsion of engine oil and water/moisture. While it can be a symptom of a catastrophic blown head gasket, it is more commonly
An oil dipstick is a simple tool used to check an engine’s oil level and condition. It allows you to see whether the oil is at the proper level and observe its color, thickness, or
What Does 5W-30 Mean? (Oil Number Breakdown) 5W-30 refers to an engine oil’s viscosity rating, showing how it flows in cold and hot temperatures. The “5W” indicates the oil’s ability to flow in cold weather
Engine oil viscosity ratings show how thick or thin oil is at different temperatures and are written in formats like 5W-30 or 10W-40. The number before the “W” represents cold-temperature flow, with lower numbers flowing
In dexos2 vs dexos1, dexos1 fits gas engines; dexos2 fits diesel systems. Dexos1 is formulated mainly for gasoline engines, with modern versions (Gen 2 and Gen 3) focusing on protecting against low-speed pre-ignition (LSPI), improving
Yes. Valvoline High Mileage is a quality oil that protects older engines (typically over 75,000 miles). It’s formulated with special conditioners and seal conditioners that help reduce oil leaks, minimize wear, and protect aging engine
High mileage oil is designed for vehicles with 75,000 miles or more, while regular oil is intended for newer engines. High mileage oil contains seal conditioners, detergents, and additives that help reduce leaks, oil consumption,
