ITR 4T Presto oil is a superior, high-performance four-stroke engine lubricant. The fluid is blended from high viscosity index base stocks and additives to meet the required specifications.  

Why Use ITR 4T Presto Engine Oil?

Use ITR 4T Presto for these benefits;

  • The oil is blended from high viscosity index base stocks and specially formulated additives.
  • ITR 4T Presto meets API SM and JASO MA2 and API standards.
  • The lubricant protects critical engine parts like bearings, gears, camshafts, cylinders, and pistons. 
  • The oil allows for higher load capacity.

The Meaning of SAE 15W50 Engine Lubricants

ITR 4T Presto is classified as SAE 15W50

  •  SAE means Society of Automotive Engineers
  • SAE 15W50 refers to the SAE class lubricant classification. 
  • SAE per viscosity classifies lubricants. Viscosity is the flow of the fluid depending on the operating temperature. 
  • Class 15W50 engine oils belong to the category of multi-grade lubricants. The oil displays good flow properties in both warm and cold temperatures. 
  • 15W means the flow in winter, hence the “W” in the classification number. The oil still flows and can be pumped at -25°C. 
  • 50 refers to the flow property of the engine oil at 100°C operating temperature. 
  • The Kinematic oil at 100°C ranges between 16.3-21.8 mm²/s.

What is the difference between 10W40 and 15W50?

  • 10W40 oil is thinner, flows better at high temperatures, and leaves no residue in the engine.
  • 15W50 engine oil is better for winter than 10W40 fluid. 10W40 is thicker and denser than 15W50.  

Which engine is oil better, 15W40 or 15W-50?

  • 15W50 viscosity is often recommended for high-performance engines. It is used for motorsports engines that are stressed and have a high revving plus heat. 
  • 15W50 fluid is much more suitable for your four-stroke engine compared to 15W40. The lubricant has the recommended viscosity grade for four-stroke engines.
  • The two lubricants have the same viscosity. However, 15W40 has a higher resistance to warm temperatures compared to 15W40.

Frequently Asked Questions

API is an acronym for the American Petroleum Institute. The body regulates and gives  engine engine and diesel oils performance standards. 

Other such regulators include, the ACEA (European), JASO (Japan) and the US Military, and BIS (Bureau of Indian standards).

The highest API for petrol engine motor oils today is API-SP. Category classified from API SA, SB, SC, SD, SE, SF, SG, SH, SJ, SL, SM, SN &amp; now SP. 

Similarly, the API designates the performance of diesel engine oils; the highest specification is API CK4. Category classified from API CA, CB, CC, CD, CE, CDII, CF, CFII, CF4, CG4, CH4, CI4, CJ4, and latest CK4. 

For Automotive gear oils, they use API GL-1 to the highest GL-5.

The single most important thing you can do to get a long life from your engine is to change your engine oil and oil filter as often as recommended by your car manual. 

A lubricant is of good quality when fresh, but after a few thousand kilometers, it is not good for your car. It can turn thick and even corrosive. Change the oil regularly to avoid such risks.
