Types Of Motor Oil- Which Is Good For You?

Oil changes are possibly the most important maintenance any driver will require in their lifetime. This grease is responsible for keeping your engine properly lubricated and absorbing excess grease to prevent overheating.

Although all motor oils serve the same purpose, there are different types of oil: synthetic oil, high mileage oil, semi-synthetic oil, and conventional oil. Below we discuss each type of oil specification.

  • Conventional Oil

This type of oil is the most traditional and comes in a variety of qualities. Conventional oil is cheaper and is recommended for older vehicle models with less complex engine designs. You can expect the change interval to be between 3,000 and 5,000 miles.

  • Synthetic blend Oil

Synthetic blend oil offers the best performance at an affordable price. It has many of the properties of fully synthetic oil but at a much lower price.

This type of oil is a blend of synthetic and conventional base oils plus some additives for increased oxidation resistance and excellent low-temperature properties.

Synthetic blends make it easy for riders to switch from traditional to synthetic oil, which is why this type of oil is becoming more and more popular with today’s most successful riders.

  • Full-Synthetic Oil

Synthetic motor oil is made entirely in a factory or laboratory. Because of this, they tend to be a lot more consistent; It’s easier to control manufacturing processes when all your materials are subject to much stricter standards.

As such, these oils are more refined and generally better for your engine. But that comes at a price. Fully synthetic engine oil is more expensive than conventional oil.

  • High-Mileage Motor Oil

High Mileage Motor Oil is specially formulated for newer vehicle models or newer vehicles with over 100,000 miles. High Mileage Motor Oil, with its unique formulations and additives, helps reduce oil burn and prevents oil leaks that can occur in older engines.

For cars that run too long on the odometer, this added protection is vital, as oil burn is slightly more likely to be an issue, contributing to increased engine wear and reduced life.

Buyer’s Guide To Best Oil For Engines Over 100 000 Miles

Every engine has a different life and has different oil requirements. Therefore, there is hardly a product that is perfectly suited for cars over 100,000 miles. However, choosing the right oil is essential to ensure better engine performance and life.

We have created a buying guide to help you make the best buying decision. Below is a list of some things to consider before investing in the best oil for cars over 100 000 miles.

  • Viscosity Grade

When comparing motor oil for cars over 100 000 miles, you may see confusing numbers and letter codes on the packaging. These indicate the viscosity grade, a measure of the oil’s resistance to flow. Two numbers define the viscosity of an oil.

The first number ends with the letter “W” which means winter. This measurement relates to how well the oil flows when it is cold, such as when the engine starts. The second number is defined by the oil flow at normal operating temperatures.

Thin, low-viscosity oils flow more easily to protect engine parts in cooler temperatures. Thick, high-viscosity oils are often better at maintaining film strength to protect engines at higher temperatures.

  • Vehicle Age

The standard recommendation is that cars or trucks with more than 75,000 miles should use high mileage oil. However, if your car still runs like new and you use synthetic engine oil, don’t worry about the switch.

On the other hand, if you start noticing extra engine noise, oil stains on your driveway, or you have an oil leak, do your engine a favour and switch to high-mileage oil.

  • Weather Condition

Whether you live in a hot or cold climate or regularly use paved or unpaved roads, you need to think about the conditions you typically encounter while driving. Different conditions can stress your vehicle in different ways, like if you often have to change your engine oil.

The conditions in which you live and drive are important when deciding which type of motor oil is right for you.

  • Additives

As engines age, sludge slowly builds up inside them. Even regular oil changes won’t get rid of whatever builds up inside. Using a recommended motor oil for cars over 100 000 miles can reduce and remove these harmful deposits.

These additives also reduce friction on aging engine parts. This prevents your vehicle’s engine from overheating and contributes to longer service life.

  • Price

This, of course, has a huge impact on the type of high mileage oil you choose. Several high mileage oils range from conventional to synthetic varieties.

Prices are determined by brand and variety. Synthetic oils are usually the most expensive. On the hand, conventional oil costs you less.
