ENGINE OIL VARIANTS

We all love to buy a car, but the ultimate thing is to maintain our lovely car properly. But while the engine is the heart of the car, the oil is its blood. It is the biggest responsibility for every individual to know the variants of oil which are used for your car’s engine

What is Oil Viscosity?
Viscosity is a measure of the resistance of a fluid’s flow. The thicker the oil, the slower it will flow. The oils fall into viscosity grades 10W-40. 10W bit (W=winter) simply means that the oil must have a certain maximum viscosity or flow at temperature. The lower the “W” numbers the better the oil’s cold temperature performance.

What are the Different types of oils?

Fully Synthetic:
A fully synthetic oil is mainly preferred for fuel efficiency and better mileage. You can examine the product is fully synthetic or not by its SAE (Society of Automotive Engineers) rating will be 0W-30 or 0W-40 or 5W-40.
*0W-30: Fuel economy savings
*0W-40: Enhances engine performance and power
*5W-40: Ensures good cold starting

Synthetic Blend:
Synthetic blend oil is very cheap to get, but it is not highly recommended for your car’s engine. Because when it comes to fuel economy and performance, it is not up to the mark; you will have to change the oil very often. For a better way, we can use semi-synthetic which is a combination of motor oil and synthetic oil. It provides better protection against engine wear. The SAE rating for semi-synthetic includes 5W-30, 10W-40 and 15W-40.
*5W-30: Better Protection
*10W-40: Good Protection after starting out
*15W-40: Better at reducing engine wear

Conventional Oil:
Conventional oil is the origin for motor oils, and later, it was produced by the base oils of hydrocarbons, poly internal olefins, and polyalphaolefins. It’s SAE ratings are 10W-40 and 15W-40. Conventional oil provides basic protection for most engines and it’s the ideal oil for people who have very ordinary driving styles. And it’s cost-effective.
*10W-40: Basic protection for a variety of engines
*15W-40: Oil needs to be changed more often

For better performance of your engine. Oil check should be done every week as recommended by the car manufacturers. Oil consumption depends on the model of the car and driving style.

Don’t Ignore These 5 Car Engine Noises

Every car comes with some metal parts in the exterior, and fibre in the interior. It is very common for these parts to start producing noises over years of use, largely because of vehicle usage.

Engine knocking sounds:
This is heard when you drive your car by changing gears or by acceleration. It is caused because the early ignition of the air-fuel mixture has not produced the minimum power at the right time. In this case, check your engine oil level. If you find any faults, take it to your nearest service centre. Sometimes proper tuning of the engine could fix this issue.

Pinging on cold start:
This noise is caused by the fuel mixture in the engine cylinder being ignited too early by the heat of compression. We can hear this noise during acceleration of the vehicle. As the engine gets older, it will start to ping more on cold start.

Tapping sound from the engine:
The tapping sound from the engine is due to the low oil level or loose components. You can check your oil level using the dipstick. When you rev, the engine tends to produce more tap or upper valve train noises.

Loud squealing:
Loud squealing noises come from the internal engine and is caused by the belts. In a car, there are multiple belts: one for power steering pulley and one for the AC compressor. The belts generally slip from the pulley because it’s worn out. This sound is louder when you start the engine cold and fades away as you accelerate.

Grinding noise:
This is one of the common engine noises heard frequently. This noise is caused by the driver when shifting the gears; because when you apply the gear with half clutch, then there will be a grinding noise. If you are doing so, avoid it because it can damage the entire engine system.

Check the oil level regularly; because in a car, noises arise primarily because of the low level of oil. The other common thing is a bad belt, which can cause squealing noises. If you find worn-out belts, it’s time to replace them.
