Is 20W-50 a good oil?
20W-50 motor oil is a great high-performance, heavy loading oil that holds up well in extremely hot climates.
What is 20W-50 used for?
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.
Is 20W-50 better than 5w30?
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.
What does 20 50 SAE oil mean?
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. Most modern oils are 10W40 or even 5W40.
Can thick oil damage 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.
What oil can I use instead of 20W50?
Re: Substitute For 20W-50 engine oil? 5w50, 15w50 and 10w60 tend to be the alternatives.
What happens if I use 20W50 instead of 20W40?
20W50 will hold on to the viscosity marginally better than 20W40 when the engine gets hot. However, 20W50 mineral oil will cause more sludge than a similar 20W40 because 20W50 will have more viscosity improvers. Pulsar 150’s manual recommends 20W40, but you can use either, not much of a difference.
What’s the best oil for older cars?
When you’re choosing the best oil for older cars or high mileage engines, there are several criteria you can look at.
- Pennzoil High Mileage Conventional Motor Oil.
- Castrol GTX Part-Synthetic High Mileage.
- Valvoline MaxLife High Mileage Synthetic Blend.
- Mobil1 High Mileage Engine Oil.
- Amsoil Premium Protection Motor Oil.
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.
Which is better 20W 40 or 20W 50?
20W40 is suitable for hotter climates and will not cause sludge as opposed to 20w50 which is more appropriate for hotter conditions.
What happens if I 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.
Should older cars use thicker oil?
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.
