To a car, engine oil is like blood to a human. It’s safe to say that engine oil is essential to the proper functioning of any motor vehicle. It prevents deterioration of car parts even when engine temperatures reach 120 degrees, which is dangerous for many of them.
Furthermore, the vehicle’s performance can suffer greatly if the incorrect viscosity of engine oil is used. In addition, the engine will surely seize if oil leaks, costing a lot of money to fix. Thus, it is crucial to understand how to pick the best motor oil for a vehicle.
It’s important to know the recommended oil grade for the engine before making a purchase. If you look at the manual for your car, you will find the same information. Learn all about the different types of engine oil and which ones are best for your car and its needs in the next section.
The American Petroleum Institute developed this system to rate the quality of motor oils. To find out which API standard is recommended by your vehicle’s manufacturer, check the manual that came with your vehicle.
The engine oil’s thickness and its ability to withstand stress are both set by its viscosity grade. In colder climates, thinner motor oil is preferable, while in warmer climates, higher-grade motor oil is advisable. Due to the high temperatures their engines operate at, performance vehicles also require oil with a higher viscosity.
Two numbers, such as 10W-30, 0W-40, 15W-40, or 5W-30, designate the engine oil’s viscosity. An engine oil with a cold-start viscosity grade of 5W, for instance, has a viscosity grade of 5W-30. Since engine oil of grade 0W-40 is thin enough to flow through all the moving parts, it enables a vehicle to be started from a cold start even in sub-freezing temperatures.
When operating in moderately hot conditions, 10W-30 is a good choice for oil. Engine oils with a lower low-winter (W) viscosity flow more freely within the motor.
Remember that in the case of 5W-30, the 5W indicates the viscosity and the 30 indicates the thickness of the oil at 100 degrees Celsius. When it comes to motor oil, it’s best to stick to the manufacturer’s recommendations, as “40” grade oil is thicker and may cause damage. Even so, it does better in warmer climates.
The best protection against the wear and tear caused by braking, accelerating, and using the clutch is what synthetic oil is designed to provide. So, if you frequently drive in congested areas, it’s in your best interest to switch to synthetic oil, which results in less sludge buildup. It works best with vehicles that prioritise speed or handling, and it can even help increase gas mileage.
Improved refinement and reduced NVH are additional benefits of using this oil. Those who frequently go on extended trips will benefit the most from it. Price per litre for fully synthetic oils typically ranges from Rs 1050 to Rs 1250. There is a one-year or 10,000-kilometer lifespan limit for fully synthetic oil.
If you drive less than 10,000 kilometres per year, semi-synthetic oil can be a cost-effective alternative to fully synthetic oil. However, if you plan on doing a lot of miles per gallon, you should switch to fully synthetic oil because the semi-synthetic variety provides less protection and causes more component wear and tear.
Oil changes for semi-synthetic vehicles should be made every 6,000 to 7,500 kilometres or every 12 months, whichever comes first. If you have a car with a small engine and don’t drive it very often, mineral oil is the most cost-effective option.
Unfortunately, it provides significantly less safety than synthetic oil. It’s also considerably cheaper. Whether you drive 5,000 kilometres or 6,000 months, you should change your oil every 5,000 kilometres or every six months.
However, when it comes to the replacement schedule, it is best to consult the owner’s manual and adhere to the guidelines.
Thus, the consequences of using low quality engine oil or the incorrect grade of oil for a vehicle can be severe. This is because using the incorrect fluids increases friction within the engine, which speeds up the breakdown of those parts.
To rephrase, the data suggests that, despite additives, premium oil may not make a noticeable difference in engine longevity. As far as the oils’ chemical compositions go, there isn’t much of a difference between them.
Negative outcomes are possible from using the incorrect motor oil. It’s possible for the engine to lose power, make a lot of noise, or even stop working altogether.
Engine damage and increased gas consumption are just two of the costs associated with using inferior oils. If you use an oil that doesn’t meet the manufacturer’s specifications, you risk damaging your engine and nullifying the warranty on your vehicle.
The highest quality oil (like Texas’s West Texas Intermediate, or WTI) has a lower sulphur content and a lower density, so it sells for a higher price. There may be a wide range of costs because of variations in product quality.
