Is it OK to use 20w50 oil?
If an engine oil has a high viscosity, this means that it is thick; a low viscosity means that it is thin.
Select an engine oil with an SAE (viscosity) classification suitable for the prevailing outside temperatures.
F, and 20W50 is OK to use at ambient temperatures above 23 deg..
Will 20w50 increase oil pressure?
With 10w30 the engine will produce a maximum of 55 psi of oil pressure at operating temperature. With 20w50 racing oil and the same operating conditions, it will produce 70 psi of oil pressure.
What is 20w 50 oil used for?
SAE 20w-50 Oil – Conventional & High Mileage 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 Thicker oil better for 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.
What oil is best for older engines?
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.More items…•
What oil is thicker 10w40 or 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.
Is it bad to mix 10w40 with 20w50?

Can I use 10w40 in my Harley?
If you’re going to be riding in below 40° ambient temperatures HD does recommend 10W-40 but unless you are, it’s a poor choice for the engine. You can use 10W-40 in the primary, though. I use Mobil 1 Racing 4T 10W-40 synthetic in the primary and it works well.
Can I use 10w30 instead of 20w50?
SAE 20W50 is thicker than 10W30, so it’ll be longer to reach your engine parts during cold start, but the 20W50 could give your engine extra protectiom when it’s heat and being used for long time running. The sound would be smoother than the 10W30 even you get less responsive on the acceleration.
Can you mix different engine oil weights?

Is 20w50 good for high mileage?
The viscosity level of engine oil 20W50 is geared toward racing engines, as opposed to high-mileage engines, that run extremely hot and need heavy load operation. … Since its viscosity is so great, it can drag down the functioning of the crankshaft, resulting in less horsepower.
When should I use 20w 50 oil?
20-50 oil is an extremely viscous oil. This oil is suitable for hot climates and will provide more protection in hot weather than 10-30 oil will. 20-50 oil is also a good choice for some older vehicles. Since 20-50 oil is very thick, it may help prevent engine leaks in old cars.
Can you mix 5w30 and 0w20?
In summer the viscosity becomes higher due to temperature. … 20 is the finishing weight or how thick it is, when the engine is at operating temperature. 5w30 can be fully synthetic, however, putting it into your engine which is designed for 0w20 is a bad idea.

Should I use thicker oil in a high mileage engine?
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.
Will thicker oil stop oil burning?
A lot of oil-burning takes place because an engine’s piston rings are worn out, and thicker oil won’t fix that. Using thicker oil is also a particularly bad solution for modern cars. … They use low-viscosity oils that splash easily all over the moving parts of the engine to make sure they’re all lubricated.
Can I mix synthetic and regular oil?
The short answer is… yes. If you don’t have a choice, adding synthetic oil to regular oil can help you out in a pinch.
Will heavier oil hurt my engine?
Not only that, but the engine will waste energy pumping the thicker motor oil, reducing fuel economy. Since thicker oils don’t transfer heat as well as thinner oils, operating temperatures will increase, too, possibly leading to accelerated chemical break down and harmful sludge and deposits.
When should I use 10w40 oil?
Using 10w30 oil in cold weather will help reduce excessive oil temperatures and drag as the engine warms up. Using 10w40 oil in the summer will help the oil stick to internal components in high temperatures, avoiding the wear and tear from metal-to-metal contact between moving parts.
Can I use thicker engine oil?
Using oil that is thicker than recommended may lead to a decrease in fuel economy, a higher load on your engine, and even a shorter life for your engine. Conversely, using thinner, lighter-weight oil than recommended can cause excessive wear and shorter life.
