Engine oil is compared to human blood. As humans can’t servive with contaminated blood, vehicle engines are the same. So you first check the oil quality to get maximum engine performance. 

  • Castrol Edge 

Meeting the industry standards like American Petroleum Institute (API) and European Automobile Manufacturers Association ACEA A3/B4, Castrol ensures its quality.

  • Castrol Edge 

This oil contains more zinc, phosphorus (about 800 ppm), and many other anti-wear additives in its formula. So, all those chemicals will prevent premature damage and aging, reducing metallic fatigue on the high-tension valve springs. That will create extreme metal-to-metal contact that leads to an internal higher temperature. 

  • Mobil 1 

Around 1,000 ppm of ZDDP and a higher amount of phosphorus are in the Mobil 1 engine oil recipe. All those chemicals work as anti-wear additives to protect engines from heat, pressure, and sludge formation. That’s why your engine performs better, like its pristine condition, even after many years of running.
