Quick Answer: Does Thicker Oil Run Hotter?

What is 20w50 oil for?

20W50 motor oil is a high viscosity oil that provides a cushioning and protects against metal-to-metal contact.

It is also a more effective sealant than thinner oils.

Both of these benefits extend engine life..

Which oil is thicker 5w30 or 10w40?

A 10w-40 motor oil is a thicker oil at startup than a 5w-30 motor oil. Therefore, 10w-40 oil clings to the engine’s moving parts more than the lower viscosity 5w-30 oil.

Is 10w40 good for high mileage?

The slightly thicker oil film from the heavier base weight oil – 10W – can help protect worn engine bearings as well. As long as you’re not hearing knocking or serious mechanical noises from the engine, the heavier oil should buy you many more miles of service from your vehicle.

What happens if I put 10w40 instead of 5w30?

If you use 10-w-40 instead of 5-w-30 specified by the manufacturer then the viscosity of 10-w-40 used by you will be higher and oil thicker than what is specified during winters. Similarly the oil viscosity will be higher and oil thicker than specified during summers.

Does thicker oil run cooler?

If it makes you feel safer, run a bit thicker oil but with thicker oil, comes increased engine wear at cooler temperatures and increased heat into the oil through more friction and less flow (flow and pressure are inverse , as you increase pressure, you decrease flow).

Is 10w40 good for summer?

However, if you live in warmer or hotter regions, you’d definitely want to grab the 10W40 engine oil. This is especially important during hot summer days when the scorching heat of the sun can really amplify the heat generated by your engine.

Which 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 10w 40 too thick?

Multi-grade oils could stay as close to the optimum viscosity over a range of temperatures – not too thick when it is cold and not too thin when it is hot. … The difference between 10W-30 and a 10W-40 is the high temperature viscosity. Obviously, a 10W-40 is thicker than a 10W-30 at high temperature.

Is it OK to use 10w40 instead of 10w30?

Overall the 10W30 will be the more appropriate oil for cold weather and non-performing engines while 10W40 is perfect for warmer temperatures and older vehicles. But, if you are still not sure what to use, talk to your local mechanic or check the vehicle’s manual.

Is 10w40 good for winter?

Yes, although they are both technically 10w oils, a 10w-40 is much thicker in cold conditions compared to a 10w-30.

Does engine oil get thicker when hot?

Oil weight, or viscosity, refers to how thick or thin the oil is. … Your engine needs oil that is thin enough for cold starts, and thick enough when the engine is hot. Since oil gets thinner when heated, and thicker when cooled, most of us use what are called multi-grade, or multi-viscosity oils.

Should I run thicker oil in the summer?

As a general rule, you’ll get the best protection in the summer when you use a slightly thicker grade of oil, such as a 10W30 instead of a 5W30. Engines need a thicker oil in the summer months because of the summer heat and its effects on thinning the oil out.

Can I use 20w50 oil instead of 10w30?

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.

Does thicker oil affect performance?

Engine Oil DOES Affect Performance Wonder no longer. The oil you choose for your car’s engine makes a difference in its economy and power production. … Your engine has to work harder to move internal parts with thicker oil in the crankcase, sapping energy before you ever have a chance to use it.

When should you use 20w50 oil?

Warmer Temperatures 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.
