What Engine Oil to Use for Old Cars

Introduction

When it comes to maintaining your old car, one of the most important things you can do is to use the right engine oil. The wrong oil can cause premature wear and tear on your engine, and can even lead to catastrophic failure.

In this article, we will discuss the different types of engine oil available, and help you choose the right one for your old car.

Types of Engine Oil

There are two main types of engine oil: conventional oil and synthetic oil.

Conventional oil is made from refined crude oil. It is the most common type of engine oil, and is generally the most affordable.
Synthetic oil is made from synthetic hydrocarbons. It is more expensive than conventional oil, but it offers a number of advantages, including:

Improved engine protection
Longer oil change intervals
Better fuel economy

Choosing the Right Engine Oil for Your Old Car

When choosing an engine oil for your old car, there are a few things you need to consider:

The age of your car. Older cars typically require a thicker oil than newer cars.
The type of engine in your car. Some engines require a specific type of oil.
The climate in which you live. If you live in a cold climate, you will need an oil that is resistant to thickening at low temperatures.

Once you have considered these factors, you can consult your vehicle’s owner’s manual to find the recommended oil type and weight.

Recommended Oil Types for Old Cars

Here are some general recommendations for the type of oil to use in old cars:

For cars built before 1970, use a conventional oil with a weight of 10W-40 or 15W-40.
For cars built between 1970 and 1990, use a conventional oil with a weight of 5W-30 or 10W-40.
For cars built after 1990, use a synthetic oil with a weight of 5W-30 or 0W-40.

It is important to note that these are just general recommendations. You should always consult your vehicle’s owner’s manual to find the recommended oil type and weight.
