Should You Switch to Synthetic Oil after 100k Miles?

Motor oils need proper temperature and viscosity to flow and cling to the oscillating parts. In a high mileage engine, an increase in temperature is observed. With this, most conventional engine oils become useless in most cases, and they do not provide the efficiency they used to offer.

Synthetic Oils are made thicker with the help of additives (viscosity modifiers), which help them provide better results at high temperatures.

Because of this sudden lack in fuel efficiency and frequent oil change requirements at worn-out engines, it is recommended that you switch to synthetic oil after 100k miles.

Most people are hesitant to change to synthetic oil because of some myths and rumors.

We are here to provide you with all the necessary information there is about switching to synthetic oil after 100k miles.

Switching to synthetic oil after 100k miles.

What happens to all old machines and instruments?

They start to catch dust and impurities more than they used to, also they heat up pretty fast, right?

Because of these complications, they start to wear out fast, and their efficiency starts to drop. The same is the case with engines.

High mileage engines are prone to these problems.

If you are having the same problems, switching to synthetic oil may be the solution.

There is a reason why synthetic oils are called high mileage oils.

They are designed to help maintain high mileage engines.

They have fewer impurities as compared to conventional oils, and they also have a detergent component to them.

It helps with the longevity of your engine by cleaning up sludge buildup.

The oil will help you with the maintenance of your engine after 100k miles.

It is all the more reason for you to switch to synthetic oil.

Can I switch to synthetic oil before 100k miles?

It is not a requirement that you have to use it after 100k miles.

If all those benefits attract your attention and you are driving in harsh climatic conditions, why not just switch to it before 100k?

The point of changing to synthetic oil after 100k miles is just because the engines develop a need for maintenance at that point, and synthetic oil can help with that.

There is no harm in switching to synthetic before the 100k mark.

When not to switch to synthetic oil?

You can use synthetic oil in most cases but there are some when you should avoid it or discontinue use if your car already has minor leakage problems.

Synthetic oils have a better flow, so they tend to seep out of leakages more as compared to other oils.

While switching to synthetic oil you should monitor your oil for a period of 3 to 4 weeks.

If you see that your oil level is dropping continuously, you should discontinue use. If the leakages are just temporary in this period, and they disappear later, then all is good.

How is Synthetic Oil different?

Synthetic oils are infused with artificially synthesized chemical compounds.

They have two components to them, the primary component is the same as any, which is a base oil that is extracted from crude oil.

The other component is a set of additives that assist in the modification of oil.

Synthetic oils are generally thicker with more temperature resistance.

They are modified both physically and chemically to suit conditions better.

They also provide better lubrication when compared to other conventional motor Oils.

Does Synthetic oil cause leaks?

When it comes to leaks, saying that a certain oil causes a leak is not right.

So, the answer to your question does the synthetic oil case leak is simply NO!

Synthetic oil flows better, so you can say that they are more likely to leak than conventional oil.

They will leak out of the engine if and only if there is a way for it to leak out.

But thinking that they will be the cause of the leak is just inappropriate.

Can you mix synthetic and regular oil?

The oils can be mixed and can be used with no negative impacts.

The only downside to this will be that the efficiency and benefits of synthetic oils will be diminished.

If your car has been running on conventional oil and you do not fully want to submit to using synthetic fuel, then it is fine to just get the best of both worlds.
