Can you use 10w30 instead of 5w20?

Originally Answered: Can I put 10w30 instead of 5w20? You can, but you will get worse mileage, and in most cases shorten the life of your engine, as it will take longer to pump up pressure for your bearings and lifters, and won’t spray your lower cylinders for an extra second or so on each cold start.

Can you mix 10w30 and 5W20?

Can you mix 5W20 and 10W30? Yes, you can mix both oils.

What is the difference between 10w30 and 5W20 oil?

10W30 is thicker and protect older engine with its sealing capability. 5W20 is thinner multi-grade oil that is pertinent for quick starts in the lowest temperatures. In order to protect your car from internal damages, it is beneficial to use only specified engine oil by the manufacturers.

What oil can I substitute for 5W20?

The 0W or 5W refers to the pumpability in cold temperatures. Therefore, a 0W would flow more easily than a 5W and could be an acceptable substitute. Thus, it is suitable to use a SAE 0W-20 as a replacement for SAE 5W-20 application.

What happens if I use 10W40 instead of 5W20?

And a 10W40 would invalidate your warranty… just so you know. In a 5W20 engine. You could use a 0W20 oil (I use 0W20 oil) in cold weather and it would be Ok by Ford. (they will not say it is good, but they will still honor the warranty..)

Will 5w20 hurt a 10w30 engine?

Using 5W-20 for an engine designed for 10W-30 risks having the super thin oil leak out gaskets or past the engine rings possibly leading to a low oil situation or fouled plugs. Using 10W-30 engine oil in an engine designed for 5W-20 risks not getting the thicker oil thoroughly around the fine tolerance of the engine.

Is it OK to mix 5w20 with 5w30?

It is entirely safe and okay to mix 5W30 and 5W20. Whether you’re topping your 5W30 engine with 5W20 oil or vice versa, you are definitely not triggering any harm or potential damage to the engine’s core components. Yes, the oils may have different additives; hence, the difference in their weight rating.

Is 5w20 good for winter?

5W20 motor oil is another low-temperature grade typically recommended for winter use, with a 10W-30 as an alternative for higher temperatures. This oil type is common because it provides the best fuel economy, saves fuel consumption, and has fewer exhaust emissions.

Whats thicker 5w20 or 10w30?

The 10w30 type is the thicker one and 5w20 is the thinner. A 10w30 is the same as 5w30 when at operating temperatures. Merely switching cold viscosity isn’t likely to do much for you. Instead, try a high mileage oil and see if that helps.

Which oil is thicker 5w30 or 10w30?

10w30 is thicker than 5w30 because it has a higher viscosity in low temperatures. The engine oil will flow slower than 5w30 during the cold season. Thicker or higher viscosity metal oil has a better seal compared to low viscosity oil. Thicker oil offers better lubrication of motor and engine parts.

What happens if you use 5w30 instead of 5w20?

Due to the increased resistance of the thicker 5W-30 oil, your engine will produce slightly lower fuel economy and horsepower output. You also risk engine damage when using 5W-30 instead of 5W-20, as the internal engine components are specifically designed to be used with 5W-20 motor oil.

Should I use 5w20 or 0W20?

Sure, 0W20 will flow better than 5W20 at low temperatures, but the difference is minimal and both versions run thin in cold conditions. However, if you live in an extremely cold region, the 0W oil will do less damage than the 5W oil while starting the engine.

Should I use 5w20 or 5w30?

5w30 is by far the most common on the market. However, the lower viscosity version, 5w20, is also recommended by many vehicle manufacturers. 5w20 can provide better protection in climates with lower temperatures as the lower viscosity will improve oil movement in freezing conditions.

Should I use thicker oil in a high mileage engine?

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.

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.

Will it hurt to use 5w20 instead of 0W20?

You can use 5W20 synthetic instead of 0W20 synthetic if you want, if the warranty is no longer an issue. Even if you’re still under warranty It’s extremely unlikely that the 5W20 synthetic will ever cause you a problem.
