Liqui Moly Top Tec 4100 5W-40 - 1 Litre ⚫ Review 🏆

Liqui Moly is a German company that has specialized in motor oils and additives since 1957. They are known for producing premium quality lubricants and their Top Tec line represents some of their most advanced synthetic motor oil formulations.

Top Tec 4100 5W-40 is part of Liqui Moly's line of full synthetic motor oils designed to meet the latest specifications for gasoline and diesel engines. It features innovative "synthesis technology" which combines synthetic base oils with advanced additives for optimal all-round protection.

Product Overview

Liqui Moly Top Tec 4100 is a fully synthetic motor oil with a viscosity grade of 5W-40. It comes in a 1 liter bottle, which is a common volume for engine oils.

The 5W-40 viscosity grade means it has characteristics of both a 5W and 40 weight oil. The 5W refers to the oil's behavior at cold temperatures, with a lower number meaning better flow at low temps. The 40 refers to the viscosity at high engine temperatures. So 5W-40 provides low temperature fluidity along with high temperature viscosity.

Top Tec 4100 utilizes Liqui Moly's "Synthesis Technology," meaning it is a fully synthetic oil. Synthetic oils are chemically engineered to have improved properties compared to conventional mineral oils. They provide better protection, performance, and efficiency in most engines. The "100" refers to this oil meeting the latest API SN PLUS standards for gasoline engine performance.

Benefits

Liqui Moly Top Tec 4100 offers several key benefits that make it an excellent choice for your vehicle's engine.
