Which 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.
What’s the thickest car oil?
The thickest viscosity grade for automotive applications is a SAE 60 which has a viscosity between 21.9 and 26 cst at 100c. Pretty thick stuff. Used in older engines, large Diesel engines.
Can I use 20w50 oil in my lawn mower?
The short answer is yes, you can use 20w50 oil in a lawnmower but results may vary. … This kind of oil is not designed specifically to be used in a lawnmower. 20W50 is actually a fairly specialized petrol engine oil formulated for use in engines made generally before 1980.
Is 20w50 good for high mileage?
Considerations. 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.
Will thicker oil damage 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.
Should I use thicker oil in an older 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.
What weight oil is best for high mileage?
Best Motor Oil for High Mileage Engines [4 Recommended Buys]Valvoline (VV150-6PK) MaxLife 10W-40 Higher Mileage Motor Oil. … Pennzoil High Mileage Vehicle Oil. … Mobil 1 45000 5W-30 High Mileage Motor Oil. … Castrol 06470 GTX 20W-50 High Mileage Motor Oil.
When should I use 20w50 oil?
20W50 motor oil is suitable for warmer climates, where the higher temperature causes the oil to thin. It is also useful for vehicles subject to hot temperatures and for those used for high-stress activities such as hauling or pulling trailers.
Is 20w50 thicker than 30w?
20w50 will be thinner when it is cold but at a 100 degrees it will be thicker than a 30 wieght.
Is 10w30 thicker than SAE 30?
Nope. SAE 10W30 is an oil that has SAE 10W viscosity(thickness) at low temperatures, and SAE 30 viscosity at high temperatures. The W stands for ‘Winter’. Note that these viscosities are relative, and standardised numbers and no absolutes, the oil doesn’t get thicker when it’s hot, it gets thinner.
Which is better 15w50 or 20w50?
The “20w50” means it flows like a 20-wt. when cold and protects like a 50-wt. when hot. The 15w50 obviously starts with a thinner base-stock with more VI’s and a has a broader temperature range.
What is the difference between 5w30 and 20w50?
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 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…•
Will thicker oil stop rod knock?
Once an engine starts to knock, the rod can fracture without warning. … So, the first job in slowing down the deterioration is to thicken your oil viscosity and boost the oil pressure inside the engine. You’ll know if it is working because it should quiet the knocking.
Is 5w30 good for high mileage?
High-mileage motor oil doesn’t hurt and it could prevent leaks from starting. … Some mechanics recommend switching to a thicker (higher viscosity) oil — such as 10W-30 full synthetic oil instead of 5W-20 full synthetic — or using oil additives to stop leaks.
