What happens if I use 15W40 instead of 20w50?

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.

Can I use 15w50 instead of 20w40?

There won’t be much changes or problems in changing 15W-50 grade to 20W-40 but as days passes it might bring slight changes to your engine due to different viscosity in both oils.It is recommended to use the same lube oil so that you can enjoy the benefits for some more extra years.

Can we use 15W40 instead of 20w40?

Originally Answered: What is the difference between 15w 40 and 20w 40? 40 is viscosity at 100°C , that means both have around same viscosity at 100°C but viscosity of 15w40 at 40°C is at 109 and 20w40 at 40°C has 121, 20w40 is thicker than 15w40 and and it is not recommended for cold climates.

When should I use 15w50 oil?

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.

Can I use 15W40 instead of 15w50?

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.

What is 15W-50 oil used for?

What is the difference between 15W-40 and 15W-50 oil?

15w-50 has a viscosity grade of 40. It is thicker and heavier as compared to 15w-40. It has been recommended for engines that have high performance. Most essentially used in motorsports, they are equipped to operate under heated and stressful conditions.

When should I use 15W50 oil?

What is the difference between 15W-40 and 15W 50?

What is 15W-40 oil used for?

15W40 oil changes less with change in temperature. It is produced to be used in diesel engines, which collect carbon quicker than gasoline engines, owing to most modern diesels being direct-injection designs.

Is 15w40 too much oil for my engine?

15w40 is harder for your engine and actually reduces horsepower in cold environments but if you are using light oil in the tropics then you risk early engine failure. The answer to your question is where do you live, what is the temperature of the engine environment and how big and heavy is the engine.

What is the difference between 10W40 & 20w50 oil?

Most modern oils are 10W40 or even 5W40. The numbers 20W50 refer to the viscosity of the motor oil, set by the Society of American Engineers. This refers to its fluidity or thickness. The “20W” indicates how quickly the engine will start when cold or in cold weather.

What does 20w50 mean on a car?

The “20W” indicates how quickly the engine will start when cold or in cold weather. The “50” refers to the thickness of the oil when the motor has been running for a while. 20W50 motor oil is relatively viscous and thick.

Can I use a 15w50 instead of 20w50?

Yes. You can. Although switching from 20w50 to 15w50 has it’s own share of pros and cons. The advantage is you get better cold start. Hence it’s useful only when temperatures are low. The cons being that it won’t be lasting as long as 20w50.
