Quick Answer: Should I get thicker oil in an older engine?

Will thicker oil damage my engine?

Using oil that is thicker than recommended may lead to a decrease in fuel economy, a higher load on your engine, and even a shorter life for your engine. Conversely, using thinner, lighter-weight oil than recommended can cause excessive wear and shorter life.

What oil is best for older engines?

It is the Valvoline MaxLife 10W-40 oil that stands out as the best for motors that are old. The additives in Valvoline are enhanced. Your motor will perform better when you use the additives.

Is 10w40 better for older engines?

Is 10w40 Better For Older Engines? When you put more pressure on your vehicle’s engine at high temperatures, 10w40 will reduce wear and tear on the engine and make it more durable. 10w40 is also an excellent choice for older vehicles.

Is it better to use thicker oil in high mileage engine?

Yes, High mileage engines will benefit from more viscous oils. Thicker oils have additives such as conditioners, antioxidants, seal swells, detergents and friction additives that are engineered to take care of high-mileage engines. Gaskets, seals, and non-metal parts start decaying as an engine ages.

What happens if I use 20w50 instead of 5W-30?

There is actually a difference between 20w50 and 5w30. As a result, the fuel efficiency will be reduced, the horsepower will be reduced, and the engine damage will be greater because the rotate will be harder. Make sure you trust the engineers who built your vehicle.

Can I put 10w40 instead of 5W-30?

Your vehicle does not use 5W-30 oil. The recommended oil viscosity for your vehicle, according to Kia documentation, is 10W-40. If you drive the vehicle in exceptionally cold weather, well below 32 degrees, you can use 5W-30 oil but even 10W-40 is still perfectly OK to use if outdoor temperatures are below freezing.

Should you use synthetic oil in older engines?

It protects better, performs better, and lasts longer, and it’s no longer made with a chemical compound that could hurt older vehicles. Modern synthetic oil is safe to use in all types of vehicles, ranging from new purchases to classics to aging not-so-classics.

Which oil is thicker 5w30 or 10w30?

10w30 is more viscous than 5w30 and is also the thicker fuel amongst the two. This changes the efficiency of the two oils as well. 5w30 is less viscous and therefore can reach even the difficult parts of the engine for lubrication. But this is not possible with 10w30 since they are thicker.

Will synthetic oil hurt older engines?

Myth: Full synthetic oil is not good for high mileage cars or older vehicles. The myth is rooted in the idea that synthetic oil is “slipperier”—lower in viscosity, or not as compatible with seals and will therefore leak or leak more in places conventional oil might not. Again, completely untrue.

What happens if you put 10W40 instead of 10W30?

This is the reason your location is so important in selecting which oil to use. Between a 10W-30 and 10W-40, 10W30 motor oil would run smoother in colder climates while a 10W40 would be more effective in preventing engine wear and tear in warmer temperatures.

Is 20W50 thicker than 10W40?

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. The way to improve your gas mileage is to drive more efficiently and purchase a vehicle that gets better gas mileage.

Is 10W30 thicker than 10W40?

10W40 oil has a higher viscosity, retaining more thickness than 10W30 as the temperature rises. In that case, 10W-40 motor oil would technically provide better protection against engine wear contact in higher temperatures.

Is 10w40 good for high mileage?

Mobil 1 High Mileage 10W-40 motor oil is recommended by ExxonMobil for use in high mileage vehicles (even those that have used lower quality conventional oils), including: Cars.

When should I use 20w50 oil?

What Is 20W-50 Oil Used For? 20W-50 is a common motor oil used in moderate-to-large diesel and gasoline engines, high-performance motorcycle bikes, and aviation vehicles. Its resistance to thinning at high heat also makes it popular as a racing oil and high temperature driving.

Can I use 10w30 instead of 5w30?

The answer is yes. You can use 10w30 instead of 5w30 oil since both meet the SAE standard for viscosity at operating temperature. Generally, the viscosity difference between the two is neglectable.
