What is the difference between 5w 30 and 10W-40?
A 10w-40 motor oil is a thicker oil at startup than a 5w-30 motor oil. Therefore, 10w-40 oil clings to the engine’s moving parts more than the lower viscosity 5w-30 oil.
What is the advantage of 10W40 oil?
Applications of 10W-40 Motor Oil Drivers commonly use 10W-40 motor oil in vehicles with higher mileage because the oil is thicker while the engine is hot; this helps lubricate older moving parts. This oil is meant to start up vehicles in winter climates that experience temperatures of 10 degrees Celsius.
Which oil is better 10W-40 or 10W 50?
In short, you can use 10W50 if your vehicle is specified with a 10W40 grade, at the expense of a little less power and mariginally lower fuel efficiency, but using the 10W40 on a vehicle for which 10W50 is recommended, will cause faster wear.
When should I use 10W40 motor oil?
While both are low-temperature grade oils, 10W40 is thicker at high temperature; therefore, better to use in warm weather.
Is 10W40 thicker than 20W50?
The smaller number, (the 20 part of 20w-50) describes how the oil behaves at 40 deg C and a 20w at 40 deg C is about 10 times thicker than your engine wants. A 10w-40 is better at around 6 times thicker and a 0w-40 is much better at about 4 times thicker.
Which car oil is thicker?
You might be familiar with terms such as “30-weight” or “10W-30” oil. Those numbers refer to the grade. The higher the number, the thicker the oil. The lower the number, the thinner.
Is 10W40 good for summer?
Similarly, SAE 10W-40 motor oil performs well in cold weather conditions. It has the same low-temperature limits as the 10W-30 but is better in higher temperatures. Either 10W30 or 10W40 for summer use is fine; however, 10W-40 motor oil will better protect your engine.
What does W mean in 10W40 oil?
The W actually stands for “winter” but basically means “viscosity when cold.”. So 10W-40 oil acts like SAE 10 oil when it’s cold, but acts like SAE 40 oil when it’s hot. 0W-20 oil acts like SAE 0 oil when it’s cold, but acts like SAE 20 oil when it’s hot.
What is 10W40 oil used for?
A 10W40 oil is a multigrade oil that has two viscosity or flow grades. Prior to the development of multigrade oils, drivers had to use a thicker oil in summer and a thinner oil in winter. Multigrade oils contain a polymer which slows the rate of thinning as oil temperature rises.
What is the temperature range for 10W-40 engine oil?
While both winter-grade oils perform similarly and reduce drag during cold startups, the 10W-40 motor oil is more viscous in hotter climates and has a better temperature spectrum. 10W-30 synthetic oil’s range is between -25°C/-13°F to 30°C/86°F (sometimes -30°C/-22°F to 35°C/95°F) while a 10W-40 is from -30°C/-22°F to 40°C/104°F.
What is 10W40 in engine oil mean?
10w40 motor oil is synthetic motor oil that has a viscosity of 10 in low temperatures and viscosity of 40 at higher temperatures, usually 100 degree Celsius. Comparison Chart 5w30 motor oil
