The API SQ specification represents a significant step towards global harmonisation of lubricant standards, with unprecedented alignment with international specifications like ACEA (European Automobile Manufacturers’
Since March 31, 2025, a significant change has taken effect in engine oil specifications: the maximum mini-rotary viscometer (MRV) viscosity for ILSAC GF-7 and API
Lubricants aren’t just about viscosity and performance—sometimes, their colour can tell a deeper story. While most people assume a darkening lubricant simply means it’s time
During World War II, conventional mineral oils couldn’t withstand the extreme temperatures inside high-performance aircraft engines. The solution? The first synthetic lubricants were developed to
Long before synthetic and mineral-based lubricants, the earliest civilisations relied on animal fats to reduce friction and wear. Ancient Egyptians, for example, used animal-derived oils
ILSAC GF-7 and API SQ will replace GF-6/API SP on March 31, 2025—ushering in a pivotal upgrade for gasoline engine oils designed for modern, downsized
🔬 The Lubricant Lab: Sequence IVB Valvetrain Wear Test—Methodology & Advances Over IVA 🛠️ The Sequence IVB test (ASTM D8350) measures how well engine oils
Did you know that API SP engine oils undergo an entire suite of Sequence Tests before they can carry that specification label? Each test targets
Did you know that the API SP specification is not only the go-to engine oil standard for modern turbocharged, gasoline direct-injection (GDI) engines, but it’s
