  2. Check the Viscosity Grade:

    The viscosity grade is a factor in the thickness of a lubricant. It allows you to determine the stress holding capacity of engine oil as thin engine oil works well for winters, but a high-grade or thick lubricant is good for summers.

    This is also the reason high-performance cars come with a higher viscosity oil as their engines constantly work at very high temperatures. The viscosity of a lubricant is determined through a set of two numbers, like 10W-30, 0W-40 or 15W-40, or 5W-30.

    A higher oil grade means a higher viscosity. When you use thin lubricating oil will reduce the friction in the engine, Making the flow of oil much better & easier. And when you use thick lubricating oil it works better in higher temperatures and protects the engine bearings and engine sealing by acting like a protective layer.

  3. Go with the ACEA Rating:

    The ACEA depicts the rating of a lubricant like A5/B5, A3/B4, etc. This rating is granted after considering many parameters considering the fuel economy, sludge, soot thickening, and oxidative thickening. ACEA rating of a lubricant can help you determine its suitability for your vehicle, so it’s best to keep this in mind when choosing an engine oil, particularly for a diesel engine.
