Engine Oil Guide: Types, Oil Changes & Maintenance

The Ultimate Engine Oil Guide: Types, Changing Time, and Inspection

Your engine is in constant use while you drive. However, even if your vehicle has an excellent maintenance record, it may have serious issues if you do not use the proper oil. Engine oil protects moving parts from wear, removes heat, absorbs oil from friction, and lubricates moving parts.

This engine oil guide will show you how to select the correct engine oil and what the key signs of trouble are and then provide you with an effective maintenance plan.

The Various Engine Oil Types and Their Applications.

Oils are not all the same. By knowing about the various types of engine oil, you can better decide which oil to use for your car's engine.

Conventional Motor Oil

Conventional oil is a petroleum-based oil that may work in older engines that are designed for it. It is, however, less resistant to oxidation and extreme temperatures compared to modern synthetic formulations.

Full Synthetic Motor Oil

The full synthetic oil benefits are enhanced by thermal stability, resistance to breakdown, and protection in challenging driving situations. It also helps reduce engine wear, improve lubrication during cold starts, and maintain consistent performance.

High-Mileage Motor Oil

In high-mileage vehicles, the oil may contain additives that are meant to condition old seals and to aid in minimizing oil consumption, in particular, in some engines.

Follow the engine oil for high mileage cars specifications of your vehicle manufacturer.

Motor Oil Viscosity Explained: Oil Grade Meaning

Oil viscosity is a measure of how an oil flows at various temperatures.

Knowing what the oil grade means can help drivers determine which oil to use.

0W-20 oil: This is the type of oil found in most newer engines that need a minimum viscosity.

5W-20 oil: For cars made to use this type of oil.

5W-30 oil: A common grade that has different flow properties than 5W-20 oil.

10W-30 oil: Different cold temperature flow properties than 5W-30.

5W-40 oil: Used in some engines, where a higher viscosity is necessary at higher operating temperatures.

Wondering what does 5W-30 means? The first number refers to the cold temperature of viscosity, and the second to viscosity at operating temperature.

DO NOT choose an oil because of the viscosity. Refer to the owner's manual for the engine oil guide, grade and performance level required.

When to Change Oil?

Your oil change frequency will vary based on the vehicle, oil quality, driving conditions, and manufacturer specifications. The manufacturer of oil change intervals vary from around 5,000 to 10,000 miles, depending on the vehicle.

There are a few things that can affect when you need to change your engine oil:

Frequent short-distance driving.

Long idling and stop-and-go traffic.

Dusty roads, hot or cold weather.

Extensive towing or rough riding of the engine.

Severe driving conditions as defined by the manufacturer.

For people who are not sure of the number of miles between oil changes, they should check the owner's manual or vehicle maintenance monitor.

Keep in mind, oil change mileage or time is whichever one is reached first as advised by the oil manufacturer.

How to Check Engine Oil: 5 Simple Steps

Oil checks can detect oil loss, oil leaks, and potential contamination when performed regularly. You can find these things listed in an engine oil guide for reference.

Park on Level Ground

Park on a level surface and observe the manufacturer's recommendations for engine temperature and idle time.

Take Out the Dipstick

Look in the engine and locate the oil dipstick. A newer vehicle, however, will provide a reading of the oil level electronically.

Remove and Clean

Look in the engine and locate the oil dipstick. A newer vehicle, however, will provide a reading of the oil level electronically.

Check Oil Level

Check for low engine oil symptoms. Put the dipstick back in completely and pull it out to check the oil level relative to the lowest and highest lines.

Check Condition of Oil

Check engine oil at home if there is any unusual contamination in the engine oil, if it is milky, or if there are any particles visible.

Signs Your Car Needs an Oil Change

Understanding the signs of dirty engine oil and lubrication issues can help avoid costly engine damage.

Watch for:

If the oil pressure warning light comes on when driving, stop in a safe place and turn off the engine. Never drive until the cause of the problem is fixed. Engine oil inspection is very important no matter what happens.

DIY Oil Change vs Professional Oil Change Procedure

Self-service oil change is a procedure that includes draining the used oil, replacing the oil filter, properly placing the drain plug, and pouring in the recommended oil. But an oil change done in the wrong way can lead to engine damage, leakage, or overfilling. Professional service consists of using the correct oil, changing oil filters, and leak testing, as well as being responsible for the disposal of used oil.

Engine Oil Maintenance Tips for Long-Term Protection

Periodic oil changes aren't the full answer to good engine oil maintenance.

Here are a few simple ways:

Be sure to regularly check oil levels.

Follow the manufacturer's engine oil change schedule.

Use the proper oil viscosity and specifications.

Follow the manufacturer's guidelines to change the oil filter.

Get a check on leaking or warning lights quickly.

Keep an Oil Change Checklist and Service Records.

An ongoing car oil maintenance plan helps save unnecessary wear and promotes the performance of a car engine for a longer period.
