FUCHS Silkolene Pro 4 XP 10W-50 Motorcycle Engine Oil 1L

To ensure perfect compatibility, always check your vehicle's owner's manual. You need to match two key things: the viscosity (e.g., 5W-30, 0W-40) and the manufacturer specification/approval (e.g., VW 504.00, BMW LL-04, ACEA C3, API SP). You can find all the specifications and official approvals for this oil listed in the Technical Details table above to compare with your manual.

These numbers represent the oil's thickness and how it flows at different temperatures. The number before the "W" (Winter) indicates how well the oil flows when the engine is cold—a lower number means it flows faster to protect your engine during cold starts. The second number indicates the oil's thickness and protective barrier at normal, hot operating temperatures.

Unlike conventional mineral oil which is refined directly from crude oil, fully synthetic oil is highly purified and chemically engineered in a lab, allowing synthetic oils to offer vastly superior protection, better extreme-temperature performance, and longer drain intervals because their uniform molecular structure resists breaking down under high stress.

Most modern cars require an oil change every 5,000–7,500 miles, though vehicles using fully synthetic oil can often go up to 10,000 miles or more. Always follow your manufacturer’s specific mileage and time interval recommendations in the owner’s manual.
