Question: What Oil Grade Should I Use

Say your engine needs 30-weight oil when it is running at operating temperature. Well, 30-weight oil will work perfectly well when your engine is warmed up. But when you go to start it on a cold winter morning, that 30-weight oil is considerably thicker and has a hard time moving when you turn the key.

Which oil is better 5W-30 or 10w30?

5w30 provides better lubrication compared to 10w30. It is best suited for private vehicles and light-duty diesel and petrol engines, while 10w30 is more suitable for commercial vehicles and other cars with heavy load engines.

Should I use 5w30 or 5w40?

5w30 can be used by different type of vehicles and in different range of temperatures, but is ideal for colder temperatures. 5w40 is often used in higher mileage engine sand performs better in warmer temperatures.

Which oil is better 5w30 or 10W40?

In the main, 10W-40 has higher viscosity than 5W-30 across the entire temperature range. It’s thicker, heavier.

Can I use SAE 30 instead of 10w30?

No, SAE 30 is a single viscosity oil. 10w30 is multiple viscousity. Recommended engine oil viscosity changes with temperature because natural oils change viscosity with temperature. A SAE 30 oil will thin out at higher temperatures.

Can I mix 10w30 and 5w30?

No- you wont get the desired output by mixing these two oils. Because , both have different grades, 5w30 is more light and the density is less , and is intended for light usage (scooters). Whereas a 10w30 is a higer grade with more density and suitable for more higher capacity engines.

What happens if I put 5w40 instead of 5w30?

In practice, this means that each oil is just as viscous at lower temperatures and will remain viscous at -30°C, however 5w40 oil outperforms 5w30 oils at higher temperatures, being effective up to ambient temperatures of 50°C, as opposed to 30°C.

Can you switch from 5w30 to 5w40?

There’s not going to be much functional difference between a 5w-30 and 5w-40 as there’s a lot of functional overlap in the recommendations. The lower weight might yield better efficiency under light load operating conditions, but higher weight might yield better protection under higher load operating conditions.

Can I use 5w30 instead of 5w40 VW?

As long as the oil you use is VW 502 certified, a 5W-30, 0W-30, 5W-40 or 0W-40 will work just fine.

What happens if you use the wrong oil?

Using the wrong fluid can cause poor lubrication, overheating, and possibly transmission failure. A mechanic might not be able to reverse the damage, even by flushing the transmission. Mistakenly adding motor oil or brake fluid can also destroy your transmission.

Is Full synthetic oil Better?

Is synthetic oil better for my engine than conventional oil? Yes, synthetic oil is better for your engine than conventional oil. Although conventional oil (i.e., mineral oil) can provide adequate lubrication performance, it can’t compete with the overall engine performance and protection provided by synthetics.

Do I really need synthetic oil for my car?

Yes. Some engines require the use of synthetic oil, but most do not. However, synthetic motor oil can be used in place of conventional oil even if the vehicle manufacturer does not require it.

Is it OK to use 10W40 instead of 5W30?

Your vehicle does not use 5W-30 oil. The recommended oil viscosity for your vehicle, according to Kia documentation, is 10W-40. If you drive the vehicle in exceptionally cold weather, well below 32 degrees, you can use 5W-30 oil but even 10W-40 is still perfectly OK to use if outdoor temperatures are below freezing.

When should I use 10W40 oil?

While both are low-temperature grade oils, 10W40 is thicker at high temperature; therefore, better to use in warm weather.

Is 10W-40 too thick?

10W40 oil has a higher viscosity, retaining more thickness than 10W30 as the temperature rises. In that case, 10W-40 motor oil would technically provide better protection against engine wear contact in higher temperatures.

Is it OK to put 10W30 oil in a lawn mower?

10W30 is a common motor oil grade suitable for many lawn mowers. Your owner’s manual will tell you the exact grade required, but in almost all cases 10W30 is the right stuff for a four-stroke engines. Any brand of oil that’s suitable for cars or trucks will work fine in your mower.

Can I use 10w40 oil in my lawn mower?

SAE 30 motor oil is commonly recommended for use in a lawn mower engine, but the safest best is to use the type of oil your lawn mower manufacturer recommends. Often 10W-30 or 10W-40, the same motor oil types that are used in vehicles, can also be used in a lawn mower.

Is 10W30 and SAE 30 the same?

SAE 10w30 oil has 10w thickness at low temperatures, but SAE 30 is at high temperatures. In the straight SAE, 30 doesn’t and can have immense Viscosity and helpless pumpability at low temperatures. As SAE 10w30 is not thick in low temperature, while SAE 30 is in high temperature.

Is 10w30 better for high mileage?

10W-30 motor oil makes for a decent high-mileage oil. It gives a better fuel economy while reducing the oil consumption for older engines. Older engines with more than 75,000 miles on them require a thicker oil that will properly lubricate their critical engine parts and prevent oil leaks, sludge, and deposits.

What does 10w30 mean?

Answered January 07 2020. The 10W30 designation on engine oil means that the viscosity of the oil is rated at 10W when an engine is cold and 30 when the engine is hot. This is different than an oil labelled 5W30, which has a thinner viscosity when the engine is cold at 5W.

Is 5W-30 or 10w30 better for winter?

10w30, the thinner 5w30 will circulate quicker, and flow through bearing tolerances better during an engine startup in the winter or colder climates. The “w” behind the five and the 10 indicates that those are the viscosities in colder or winter temperatures.
