Caltex Lubricants 

  Getting the Basics Right: Base Oils Lubrication has been around since the invention of the wheel. Horse-drawn carts with wooden axles used meat greases, pine tar and various forms of animal fat as lubricants. Later, Linseed oil, originally a wood preserver, briefly replaced them as the primary lubrication agent. The earliest internal combustion engines used a product derived from refined crude oil. This was the beginning of the modern base oil. As IC engines became more complex and operated at higher speeds and temperatures, there was a need for better lubrication that could keep up with modern engines. So, additives were supplemented with the base oils. This combination had improved viscosity and protected the engines from wear, friction and resisted corrosion better.  In modern cars, the base oil is still the primary catalyst for better engine performance. It forms 75%-80% of the finished product while the additives (10%-20%) and the viscosity index improver, which keeps t...

  Understanding the ILSAC Standard for Passenger Car Engine Oils As automotive technology advances, the engines in our vehicles are becoming more sophisticated and efficient. Today’s engines are designed to deliver more power while using less fuel, thanks to innovations like turbocharging, direct injection, and variable valve timing. However, these advancements also create new challenges in engine maintenance. With increased power output and tighter tolerances, the demands on motor oils have changed significantly.   This is where International Lubricant Standardization and Approval Committee (ILSAC) standards come into play. Formed back in 1992 by some of the biggest names in the auto industry—Ford, General Motors, Chrysler, and the Japan Automobile Manufacturers Association (JAMA) these standards set essential performance benchmarks for passenger car motor oils (PCMO) to ensure they meet the evolving needs of modern engines.   When it comes to ILSAC Standard for Passenge...
