Do High Mileage Cars Need Thicker Oil




Yes, high mileage cars need thicker oil. This is because the oil breaks down quicker in high mileage cars and becomes thinner. Thicker oil will help to protect the engine better and keep it running smoothly.

As cars age, they begin to rack up mileage. And as mileage increases, many car owners wonder if they need to switch to a thicker oil. The truth is, it depends on the car.

Some high mileage cars will need thicker oil, while others will be just fine with the standard stuff. Consult your owner’s manual or a trusted mechanic to see what’s best for your ride.

Is Thicker Or Thinner Oil Better for High Mileage?

We get a lot of questions about oil changes and one of the most common is, “Is thicker or thinner oil better for high mileage?” The simple answer is that it depends on your car. If you have a newer car with a tight engine, you can use a thinner oil.

This will help your engine run more efficiently because there is less drag on the parts. However, if you have an older car with more miles on it, you may want to switch to a thicker oil. This will help protect your engine from wear and tear by creating a barrier between the moving parts.

Ultimately, it’s important to consult your owner’s manual or speak with a qualified technician to determine which type of oil is best for your car.

What is the Best Oil for a High Mileage Car?

As your car’s mileage starts to rack up, you might be wondering if there’s a special type of oil that’s best for high-mileage vehicles. The good news is that there are indeed oils formulated specifically for older cars. These oils can help to extend the life of your engine by providing extra protection against deposits, corrosion, and wear.

If you’re looking for the best oil for a high mileage car, we recommend going with a synthetic blend or full synthetic oil. These types of oil contain additives that provide superior protection against engine deposits and wear. They also tend to have a higher viscosity, which can help to protect older engines from leaks and oil consumption.

Is Higher Viscosity Oil Better for High Mileage?

Viscosity is a measure of a fluid’s resistance to flow. The higher the viscosity, the thicker the fluid and the greater the resistance to flow. Higher viscosity oils are generally better for high mileage engines because they provide a thicker cushion between moving parts, reducing wear and tear on the engine.

However, higher viscosity oils can also cause problems at start-up in cold weather if they are too thick, making it difficult for the engine to turn over. It is important to consult your owner’s manual or a qualified mechanic to determine which oil is best for your particular engine.

Thicker Oil For Older Engines? Myth Busted!

Best Oil for Cars With Over 200,000 Miles

If you’re driving a car with over 200,000 miles on the odometer, congrats! That’s a significant accomplishment. But it also means that your car is likely in need of some special care and attention when it comes to choosing the right oil.

Most cars these days are designed to run on synthetic oil, which is typically more expensive than traditional motor oil. However, if your car has racked up a lot of mileage, you might want to consider switching to a high mileage motor oil. These oils contain additives that can help protect engines with higher mileages from wear and tear.

There are plenty of different brands and formulations of high mileage motor oil on the market, so it’s important to do your research to find the best one for your car. You might even want to consult with a mechanic or auto specialist who can offer specific advice for your situation.

Engine Oil for High Mileage Cars

When it comes to engine oil, there are many different options on the market. But, if you have a high mileage car, it’s important to choose the right oil for your vehicle. High mileage oils are designed for engines with over 75,000 miles on them.

These oils contain special additives that help protect your engine and keep it running smoothly. Here are some things to keep in mind when choosing an engine oil for your high mileage car: -Look for an oil that is marked “High Mileage.”

-Choose an oil with a higher viscosity rating. This means that the oil will be thicker and will provide better protection for your engine. -Make sure the oil you select is compatible with your car’s manufacturer recommendations.

If you take these factors into consideration, you can be sure to choose the best possible engine oil for your high mileage car.

Should I Use Synthetic Oil in My High Mileage Car

If your car has over 75,000 miles on it, you may be wondering if you should start using synthetic oil. Synthetic oil is designed to last longer and protect your engine better than conventional oil, so it may be a good choice for a high mileage car. However, there are a few things to consider before making the switch.

First, check your owner’s manual. Some manufacturers recommend synthetic oil for high mileage cars, while others do not. If your manual does not give a recommendation one way or the other, you can consult with your mechanic to see if they think synthetic oil would be a good choice for your car.

Second, keep in mind that synthetic oil is more expensive than conventional oil. If cost is a concern, you may want to stick with conventional oil for now and save synthetic oil for later when your car really needs it. Third, remember that switching to synthetic oil will not miraculously fix all of the problems that come with owning a high mileage car.

Synthetic oil can help extend the life of your engine and protect it from wear and tear, but it cannot undo years of damage. If you are hoping for a major improvement in your car’s performance, you will likely be disappointed. Overall, whether or not to use synthetic oil in a high mileage car is a personal decision.

There are pros and cons to both choices, so weigh them carefully before making a decision.

Thicker Oil for Older Engines

As engines age, their oil needs change. Just as our skin gets drier and less elastic with age, so too do the moving parts in an engine need thicker oil to prevent leaks and maintain proper function. While most new cars come filled with what’s called “conventional” motor oil, a switch to a synthetic blend or full-synthetic motor oil is often recommended for older engines.

The key difference between conventional and synthetic oils is that synthetics are man-made rather than naturally derived. This means they can be designed with certain properties in mind, such as increased thickness or heat resistance. For an aging engine, thicker oil is generally better.

It will help to seal up any leaks that have developed over time and also provide better protection against wear and tear. If your car’s owner’s manual doesn’t specifically recommend a synthetic oil for older models, it’s still worth considering making the switch. Not only will your engine thank you, but you’ll likely see improved fuel economy as well!


High mileage cars need thicker oil because the oil breaks down faster and causes more friction. The thicker oil helps to protect the engine from wear and tear.
