What is 20w40 oil used for?

It provides strong oil film for lubrication and total protection to engine viz. protection from rust, corrosion, with reduced wear under a wide temperature range in air-cooled new generation 4 stroke motorcycles.

Which is better 15w40 or 20w50?

If you have a new engine that takes 15w40 it is best to use 15w40, but if you have a wore down 300,000 mile engine that takes 15w40, then 20w50 is probably king because you have thicker lubrication there, and it stick on your bearings, and all around moving parts more making it not wear out as fast.

What is 15W 40 oil used for?

ADVANTAGE 15W-40 HEAVY DUTY DIESEL ENGINE OIL can be used with complete success in over-the-road diesel trucks, off-highway diesel equipment, farm tractors, and passenger cars and light trucks with diesel, turbo-charged diesel engines, or gasoline engines and is backward compatible with previous API Oil Categories.

Can I use 15W 40 instead of 20w50?

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.

Can I use 20W40 engine oil?

If you have an older car with high mileage, using 20w40 is ok. Especially if it is burning oil. I have done this with some of my prior cars and they lasted for years. The only problem is if you live in an area where winter is very cold, it may be hard to start the car with thicker oil.

What is the difference between 20W40 and 20W50?

Hot 20W40 is the same as hot SAE40, and hot 20W50 is the same as hot SAE50. At any given temperature, a higher number is thicker. But remember, the viscosity is temperature dependant. So cold SAE20 and hot SAE 20 are not the same (hot SAE20 is thinner than hot SAE40, but cold SAE20 is thicker than hot SAE40).

What vehicle uses 20W50 oil?

Suitable Vehicles 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.

Is 15w40 good for petrol engines?

In tropical weather, most OEMs still recommend multi-grade products, such as SAE 15W-40, because the lubricant flows faster through the engine than a pure SAE 40 even at higher ambient temperatures.

What does the W stand for in 15w40?

In 15W-40, the first number on the left (15 here) represents the cold temperature viscosity and contains the letter “W” (which stands for winter, engineers are so creative). For example, a 5W-40 oil will be thinner in cold temperatures than a 15W-40, but at normal operating temperatures both oils will flow the same.

Can you mix 20W50 with 20w40?

In short, unless you understand oil at a deep level – you should not be mixing oils. You would get 5w20w40w50 oil. The numbers denote the viscosity or thickness of the oils. The lower number is thicker and does a better job of protecting the hot engine from wear.

Which is thicker 10/40 or 20 50 oil?

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.
