Quick Answer

Frequent Question Is 20W50 better than 10W40?

10W40 is not better than 20W50 for high mileage. The difference between 10w40 and 20w50 is simply that the latter is thicker. As far as gas mileage goes, no oil will improve your gas mileage by changing from 10W40 to 20W50 or vice versa.

What happens if you use 20W50 instead of 10W40?

If you use 10W40 in a car that requires 20W50 for an extended period of time, you can damage the engine. If you use 20W50 in a car that requires 10W40, you can damage the engine as well.

When should I use 20W-50 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.

Can I use 20W40 instead of 10W40?

Differences between 10W40 and 20W40

20w40 oils have a higher ‘W’ number, which means they will not perform well in colder temperatures, that is the only difference between the two oils.

Will 20w50 hurt my engine?

1. Is 20W-50 Oil Bad For My Engine? 20W-50 is not a very popular oil viscosity. In the wrong engine, it can lead to sludge, excess friction, varnish deposits, problems with oil burning and oil pressure, and even affect your engine life.

Is 10w40 thicker than 20w50?

10w40 oil is a popular all-purpose oil designed in many different engines. 20w50 (also known as 10w30) is another popular all-purpose oil used in engines. The differences between 10w40 and 20w50 are small, but they have something in common: They are thicker than regular 20w50 oil.

Is 20W50 good for bike?

HP RACER SYNTEC 20W 50 is recommended for new generation geared 4- stroke bikes requiring a 20W 50 grade engine oil. HP RACER SYNTEC 20W 50 far exceeds the requirements of the bikes manufactured by HMSI, Hero MotoCorp, TVS, Bajaj etc.

Can I use 20W40 instead of 20W50?

20W40 is suitable for hotter climates and will not cause sludge as opposed to 20w50 which is more appropriate for hotter conditions. But, it has more drawbacks than 20w40. For example, it will only pass two or three cold starts in a colder climate but nothing beyond that.

What is 20W 40 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.

What is 10W 40 oil used for?

This oil weight is commonly used in diesel engines or in a smaller motorcycle engine too. The 10W-40 oil viscosity also often serves as an alternative for older engines with burning or oil leaking issues. Why is that? The 10W-40 engine oil has a thicker viscosity than, say, 10W-30 oil when the car engine is hot.

Is 20w50 good for petrol engine?

Virtually every mechanic recommends the use of 20w50. 20W-50 engine oil is no good for modern engines, regardless of the mileage. It is too thick, and flow to sensitive areas like multivalve cylinders, VVT / VANOS and any other timing adjusters that rely on instant oil pressure will be impeded.

Can I use 20w50 oil 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.

Is 20W 40 engine oil Synthetic?

MOTUL 20W40 3000 4T Plus Synthetic Blend Engine Oil (1 L)

Can I use 20W 40 instead of 10w30?

20w 40 is a thicker oil when compared to the original 10w 30 oil. So 10w 30 oil is going to flow better than 20w40 oil when you initially start it and also run it. If the oil flows better the better the oil will lubricate and protect engine parts.

Is 20W 40 good for motorcycle?

In recent years some manufactures of 4 stroke motorcycles have been switching to engines suitable for 20W40 with very promising results. They are finding it gives top-notch performance and the dirt dispensing is better.

What is SAE 50 oil used for?

Applications : SAE 50 API SN /SM/SL is recommended for the lubrication of gasoline engines for passenger cars, commercial vehicles and farm equipment as well as diesel engines for commercial vehicles and contractor equipment.

What happens if I use 20W50 instead of 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.

Is 10w40 good for high mileage?

Is 10w40 Good For High Mileage? The 10w30 and 10w40 oil options are both acceptable for your car, but if you have a high mileage car, you should use the 10w40 oil. Older engines are able to handle higher temperatures and wear and tear more efficiently with thicker oil.

What happens if I use 20W50 instead of 10W30?

The main reason for using 20w50 is to slow down oil burning. If this is the case, using 10w30 would speed up the burning. I have had oil burners before, and used 20w50 in the summer, with no problem. But, your car will be hard to start in very cold weather with 20w50.

Is 10W40 good for summer?

They are both available in pure conventional form or as high-quality synthetic grades. Either 10W30 or 10W40 for summer use is fine
however, 10W-40 motor oil will better protect your engine.

Is Thicker oil better for older engines?

Older engines use more oil, but it gives them a better fuel economy. Older engines with more than 75,000 miles on them require a thicker oil that will lubricate their critical engine parts and prevent oil leaks, sludge, and deposits from forming.

What is 10w 50 oil used for?

10W50 oil is a high-performance engine oil that offers outstanding engine reliability and temperature stability under extreme driving conditions. It’s used for a wide range of motorsports and modern engines with turbochargers.

Can I use 20W50 in a 4 stroke?

Small Engine Four Stroke 20W-50 is suitable for use in lawnmowers, generator sets and pumps, four stroke outboards / inboards, brushcutters and in other gardening equipment. It may also be used in engines that specify SAE 30 oils that are using excessive oil.

What is 5W 50 oil used for?

A 5W-50 motor oil is suited for a broad range of applications including motorsport, classic/collector cars and extreme driving conditions like towing and high operating temperatures.

Which is thicker 20W40 or 20W50?

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). As 20W50 is actually heavier oil than 20W40.

Which oil is better 10w30 or 20W40?

What The Difference 10w-30 And 20w 40? The thickness of 20w40 is higher than that of 10w30 at high temperatures. It is desirable for lubrication at operating temperatures to be high. When normal operating conditions are met, 20w40 is better than 10w30.

Which oil is best for motorcycle?

What does the 20W50 mean?

The viscosity grade 20w50 is 20 weight, 50th in weight. It is common to use the terms ‘weight’ and ‘viscosity grade’ interchangeably and to refer to them as the same thing.

What does 20W 40 oil mean?

Explanation: Multigrade oils (like your 20X40)are formulated to pass viscosity tests across a range of weights. For example, 20W40 meets the requirements for 20-weight at cold temperatures and 40-weight at high temps. Motor oil is like every other fluid in that its viscosity varies with temperature and pressure.

Can I use 20W50 instead of SAE 30?

cooler! SAE30 is very suitable for older, aged engines to use. 20w50 will work in engines for what could be described as the summer weather period. If you live in colder climes then you should really consider using 30 weight.
