Is it better to use thicker oil in older engines?
A: Yes. This is a practical method to improve oil pressure in an older, high-mileage engine. The slightly thicker oil film from the heavier base weight oil – 10W – can help protect worn engine bearings as well.
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 happens if I use 20W50 instead of 5W-30?
A 5W-30 oil is commonly used in passenger cars for normal use throughout the year. A 20W-50 oil will not protect a car as well in a cold winter and its greater viscosity will increase drag and friction in a passenger vehicle.
Will heavier oil hurt my engine?
It’s best to use the oil viscosity recommended in the owner’s manual, but using a slightly thinner or thicker oil (lighter or heavier viscosity) generally poses no long-term harm.
Is 20w50 better for older engines?
20W-50 is only used for certain older vehicles or worn engines that require the extra cushioning of a high viscosity oil. Other than that, it really isn’t a high mileage oil. This is because 20W-50 is a thicker oil, and the added resistance can cause further engine wear and damage to both newer and older vehicles.
Can you use 20w50 instead of 10w30?
It really comes down to personal preference. As your engine does put out significant horsepower, we would lean toward using 20W-50. If your engine sees very light duty or is built exceptionally tight, 10W-30 would be fine. But again, if you twisted our arm, we would give 20W-50 the nod for the thicker viscosity.
What’s the best oil for high mileage engines?

Can I use 20w50 instead of 10w30?
What happens if I use too thick of an oil?
If the oil is too thick (aka, the viscosity is high), your car may not start in cold temperatures (cold weather places more strain on a vehicle in any case). When this happens, the thick liquid can’t properly lubricate every part, and it creates enough resistance to impair the most important function–ignition.
Why is 20w50 engine oil is the best?
– Firstly, you need to make sure that your motorbike is in flat condition and on its original stand. – Secondly, before checking the motorcycle oil, make sure the engine isn’t hot. – Thirdly, don’t forget to remove the dipstick from the oil tank. – Fourthly, check the color, level, and viscosity of your 10w40 motorcycle oil.
What are the benefits of using 20w50 motor oil?
20W50 motor oil is a high viscosity oil that provides a cushioning and protects against metal-to-metal contact. It is also a more effective sealant than thinner oils. Both of these benefits extend engine life.
What is the difference between 20W40 motorcycle oil and 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.
Can you use 20w50 oil in your new engine?
It is also a more effective sealant than thinner oils. Both of these benefits extend engine life. 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.
