Engine Oil – What Does My Car Need?

AAMCO Utah • Dec 06, 2019

How to Choose the Right Type of Oil

There are a lot of different types of engine oil out there and you may be overwhelmed when you go to pick up a container from your local auto shop. What’s the difference between them all?

Viscosity

First off, the “W” in the different types of oil stands for winter. The number before the “W” designates the oil’s viscosity at zero degrees Fahrenheit. As motor oil warms, it becomes thinner and vice versa. With that in mind, you also want to know the viscosity as your engine warms. The second number in the type of oil represents the viscosity at 212 degrees Fahrenheit.

Each engine will have an optimal range for viscosity, so you should check your car’s manual to ensure you get the right type when buying your own motor oil.

Conventional vs Synthetic

Conventional oil is the standard go-to for most cars. More specifically, conventional oil with a viscosity of 5W-20, 5W-30, or 10W-30 will take care of most standard cars.

Some cars require synthetic oil – often when they have more high-tech engines, likely found with performance and heavy-duty cars. Full synthetic oil is made to have better and longer-lasting performance, plus they generally operate more efficiently at both lower and higher temperatures. However, these are more expensive and can be bad for certain engines, so it’s not recommended to buy synthetic if your car’s manual does not say to use it.

There are also synthetic blend and higher mileage oils for more specialized use. Often, synthetic blend oil may be used in pickups and SUVs to help with carrying heavier loads. If you want to keep your car around even once it’s getting up there in miles, you can use higher-mileage oil. These are formulated with seal conditioners to help restore shape and flexibility to the seals within your car’s engine.

At-Home Maintenance

There are a few things you can do yourself to make sure your engine runs well. By paying attention to certain areas of your car, you can be sure you won’t run into problems regarding your motor oil.

Check Engine Oil Level Regularly

In most cars, it’s easy to check the oil level. There will be a dipstick under your hood labeled oil – pull it out, wipe it off, then reinsert. When you pull it out again, it will show the level of oil in your engine. You can use lines marked on the dipstick to judge whether you need to top it off. If it is low, you likely have a bigger problem and should make an appointment with your local mechanic.

Shoddy Repairs

This can range from insignificant to serious, depending on what was done. Improper installation of modifications or accessories may be simple enough, but if previous mechanics did bad repair work on the engine or transmission, that can end up being very expensive down the road. A pre-purchase inspection will bring to light any of these problems before they become a huge expense for you.

Is Your Oil Service Light On?

Many newer cars have a light that will come on when you have driven a certain number of miles since your last oil change. If this is the case with your car, don’t ignore that light when it turns on. Ignoring the oil change light and putting off getting an oil and filter service done will only cause more serious problems.

 

Look for Oil Spots Under Your Car

One problem that can cause low oil levels is a leak. This could mean worn out seals or a crack in part of your engine, but if a leak is your problem, you will likely notice oil spots under your car when it has been sitting for a while. Keep an eye out for any new oil spots and schedule an auto repair service if you notice any.

Regular Oil Changes Keep Your Engine Happy

By keeping up with regular oil change services , you make sure the parts in your engine are adequately lubricated. This means you avoid causing extra damage and expensive auto repair services. It’s recommended that you have an oil and filter service twice a year to make sure your oil isn’t overly contaminated or degraded. When you get them less frequently, you may notice a difference in how your car runs and even gas mileage.
