What is the difference between 15w40 and 20w50 oil?

What is the difference between 15w40 and 20w50 oil?

20W-50 motor oil is for vehicles with gasoline engines. 15W-40 oil is for diesel applications. The difference between the two grades are just the specifications and for all practical purposes, in older vehicles without variable valve timing, the two grades of oil are interchangeable.

What is 15w-50 Synthetic oil used for?

15W-50 has historically been a viscosity recommended for high performance engines, and is used today primarily in motorsports racing where engines are stressed due to high revving and heat.

When should I use 20w50?

A SAE 20W-50 motor oil is typically used in older vehicles or in particularly warm climates. Castrol GTX 20W-50 has been specially formulated to help extend the life of your engine by keeping it free from sludge, even when operating in extremely high temperatures.

What is 20w50 oil good for?

20W-50 is a common motor oil used in moderate-to-large diesel and gasoline engines, high-performance motorcycle bikes, and aviation vehicles. Its resistance to thinning at high heat also makes it popular as a racing oil and high temperature driving.

What happens if I use 20w50 instead of 15W-40?

It is best to use the same brand, type and weight of oil you put in at the last oil change. Unless you are at the fringes of temperature range for the 15w-40 oil, putting the 20w-50 in isn’t going to change the viscosity of the oil enough to damage anything.

What is the difference between 15W and 20W oil?

The main function of these grades is to describe the viscosity of the Engine oil. Simply put, the engine oil grades help differentiate between oils with varying thickness. The higher a grade is, the thicker the oil. This means that 20W-50 grade oil is thicker than 15W-50 grade oil.

Can I use 15W-50 in my motorcycle?

Energy-Conserving Oils because of its higher viscosity. A higher viscosity oil’s resistance to flow is the reason why automobile-specific oils that are not energy conserving have been used successfully in wet-clutch motorcycles without slippage problems. So 15W-50 Mobil 1 works fine in wet clutches.

What are the benefits of using 20w50 motor oil?

Is 20W50 good for petrol engine?

Suitable Vehicles Depending on the recommendations for the particular vehicle, 20W50 oil is suitable for large or small diesel engines, gasoline engines, motorcycles and aviation vehicles. It is also suitable for both air- and liquid-cooled engines.

Can you mix 20w50 with 15W-40?

Unless you are at the fringes of temperature range for the 15w-40 oil, putting the 20w-50 in isn’t going to change the viscosity of the oil enough to damage anything.

Can we use 15w40 in bike?

no. You should not us truck oils in your bike, especially something like an R1. If you”re going to run the bike hard and hot for long stretches, like on a track, then you need to use something equivalent to Motul 15w40 (or even 15w50) that has been specially formulated for bikes.…

Is 15w50 better than 15w40?

The answer is no. 15w-50 is a more suitable engine oil for your Royal Enfield than 15w-40. As 15w-50 is the recommended viscosity grade for the Twin Spark engines that are used in their models. Both have the same viscosity but 15w-50 is more resistant to higher temperatures than 15w-40.
