How To Deal With Oil In Your Radiator

How does car engine oil work?

#driveyourlife

Youve got oil in your radiator? Is it supposed to be there? How did it get there? All great questions if your friend just asked you how to deal with oil in their radiator because you know it definitely is not supposed to be there.

Your radiator is supposed to contain coolant to help keep your engine cool because an overheating engine can cause a lot of damage. Coolant is made up mostly of 2 things, water, and glycol. Water is chosen because it is great at transferring heat. In fact, water is almost 4 times better at transfer heat than engine oil is! The glycol is in your coolant, in various forms depending on what type of coolant your vehicle uses, keeps things from freezing in the winter.

Since water is so much better at transferring heat than oil is, its important to remove any oil from your cooling system ASAP!

What Does Motor Oil Actually Do

To understand the function of motor oil, its first important to at least get a basic understanding of how your engine works. You dont need to get too technical to really understand what oil does: rather, the most important thing to understand is that there are many moving parts inside your engine. These moving parts not only rub against each other, they also produce a great amount of heat.

Essentially, motor oil acts as the lubricant that allows all of these moving parts inside your engine to rub against each other and not overheat or wear out quickly. If you were to try and drive your car with no motor oil inside of it, very quickly, that heat and friction would cause the engine to weld itself into a useless piece of metal. When this happens to a car engine, the engine seizes or locks up. Once an engine is locked up, theres basically nothing that can be done to fix it. Other than, of course, replacing the entire engine.

Obviously, most motorists want to avoid this, and thus ensure that their car has sufficient motor oil to coat and protect its moving parts against excessive wear.

In addition to the heat generated from all of the moving components of the engine rubbing against each other, engines run off of a process called internal combustion. This process of combustion produces a lot of water vapor, carbon, acids, and several other byproducts.

Why Should I Check My Engine Oil Level

The oil in your engine is one of your vehicles most important elements. It keeps all the engines internal parts moving as they should, and stops them from wearing out too quickly.

If the oil level in your engine drops too low itll stop it from working efficiency causing it to seize up, and could eventually lead to significant engine damage if not addressed.

Oil should be drained and refilled annually as part of the MOT. But that doesnt mean you shouldnt still check your levels at regular intervals throughout the year to avoid your engine running low.

What Does an Oil Change Do? How Engine Oil Works

by Aloha Auto Repair | Apr 29, 2020 | Auto Repair | damageOil

When you buy a new car, you make sure to change the oil regularly as a part of maintenance. It is highly important you do this. However, some of us who are less versed with how cars work would wonder, what exactly would happen if there is no oil in it all. Without oil, your car may run for sometime but soon it may quit. So, to protect your cars engine, you should always keep a check on the oil level in your car. You should also avoid driving it at a low oil level.

Your car oil performs many critical functions. It lubricates the parts and reduces the damaging friction. It also removes deposits inside the engine and this helps in better fuel efficiency and performance. It also protects the car engine from damaging corrosion and rust.Your cars oil is the core of your engine. So, dont ignore its importance.

Lets discuss here what damages can be caused if there is no oil in your car and what you should do to prevent any damage.

How The Engine Lubrication System Works

Alex Leanse

Engine oil serves a vital purpose: it lubricates, cleans, and cools the many moving parts in an engine as they cycle thousands of times every minute. It reduces wear on engine components and ensures everything works efficiently at controlled temperatures. Keeping fresh oil moving through the lubrication system reduces the need for repairs and makes your engine last longer.

Engines have dozens of moving parts, and they all need to be well lubricated to provide smooth, consistent performance. Oil travels between the following parts as it flows through your engine:

Oil pan: Also known as the sump, the oil pan is usually situated at the bottom of an engine. Serves as a reservoir for oil. It is where the oil collects when the engine is shut off. Most vehicles hold between four and eight quarts of oil in the pan.

Oil pump: The oil pump pressurizes the oil, pushing it through the engine and keeping the components continuously lubricated.

Pickup tube: Driven by the oil pump, this tube sucks up oil from the oil pan when the engine is turned on, sending it through the oil filter and throughout the engine.

Pressure relief valve: Regulates oil pressure for a consistent flow as load and engine speed changes.

Oil filter: Strains the oil to trap debris, dirt, metal particles, and other contaminants that can wear down and cause damage to engine components.

What About Those Long

What about those claims that certain oils can go 15,000 or 25,000 miles between changes? Is there really an oil that comes with a 300,000-mile engine guarantee? Because severe driving degrades oil additives faster, oil manufacturers often qualify their oil change recommendations in the fine print. In some cases, your driving habits may require you to reduce the advertised mileage interval by as much as half. So dont assume you qualify for the best-case scenario: Read the instructions and the warranty terms. And no matter what the companies promises are, if you skip the carmakers recommended change intervals, your factory or extended warranty will be void. So youd have to depend on the oil manufacturer to pay for repairs.

Why So Many Oils

How do I know what Oil to use in my car? Engine Motor Oil and Oil Filter

Look in auto parts stores and you’ll see oils labeled for all kinds of specific purposes: high-tech engines, new cars, higher-mileage vehicles, heavy-duty/off-road SUVs, and even cars from certain countries. You’ll see a wide selection of viscosities.

If you read your owner’s manual, you’ll know what oil the vehicles manufacturer recommended to use when it was brand-new. The manual may include a reference to Energy Conserving or Resource Conserving oils, which means that the oil passed a fuel economy lab test against a reference oil. While that doesnt always translate to better fuel economy, most leading brands have at least some viscosities that are labeled as such.

Signs Your Car Needs An Oil Change

Engine oil is like the blood of every car. The engine needs oil to lubricate its moving components and keep them operating smoothly. In fact, engines of all kinds need oil in order to function. It doesnt matter if youre using a motorcycle, generator, or even a lawnmower. If its got an engine, then it needs to be lubricated with oil.

Looking for a good online repair manual? for the 5 best options.

An engine is filled with parts that are constantly moving and rubbing together. This constant rubbing creates heat from all the friction. You need oil to flow through these moving parts so that it can absorb the heat and prevent overheating.

Oil thats in good condition accomplishes its task. Old oil doesnt and need to be replaced. Fortunately, overdue oil change symptoms are easy to spot.

  • What is a Tune-Up?
  • What Are Engine Oil Specifications

    Not all engines are the same, so it shouldn’t be a surprise that oils aren’t the same either. The specification is another way that engine oils differ.

    Car manufacturers and oil companies work together to agree performance specifications for engine oils. There are several different sets of standards around the world:

    • The American Petroleum Institute
    • The European Automobile Manufacturers Association
    • The International Lubricant Standardization and Approval Committee , or
    • The Japanese Automotive Standards Organization JATO.

    Modern car engines need oils that are really durable, and last for thousands of miles between services. Modern oils protect against corrosion and sludge formation, and contain detergent additives to keep the engine clean.

    Later specification oils are usually, but not always, suitable for older cars, while older specification oils shouldnt be used in newer cars.

    Car manufacturer’s specifications

    Many car manufacturers develop their own engine oil specifications. Most notable are Volkswagen and Mercedes-Benz, but BMW, GM, Porsche, PSA and others also have their own.

    More and more often, these are very specialised ‘long life’ oils designed to support very long intervals between services.

    • If your car’s handbook quotes the manufacturer’s own specification, you must look for this on the oil container.
    • The manufacturer may also give an acceptable equivalent ACEA or API specification, though this might be for ’emergency top-up only’.

    What Engine Oil Does

    The purpose of oil is to clean, cool, and lubricate engine components. Oil coats moving parts so that when they touch, they slide instead of scrape. Imagine two metal pieces moving against each other. Without oil they would scratch, burr, and otherwise cause damage. With oil between them, the two pieces slide with very little friction.

    Oil also cleans moving engine parts. The combustion process creates contaminants, and over time tiny metal particles can build up as components slide against each other. If the engine has a leak or isnt perfectly sealed, water, dirt, and road debris can get into the engine too. Oil works to trap these contaminants, where they are then strained out by the oil filter as the oil cycles through the engine.

    The spurt holes spray oil onto the undersides of the pistons, which creates a tighter seal against the cylinder walls by forming a very thin layer of fluid between the parts. This helps improve efficiency and power, as the fuel in the combustion chamber can burn more completely.

    Another important purpose for oil is that it carries heat away from the components, extending their life and preventing engine overheating. Without oil, the components would scrape against each other with bare metal-on-metal contact, creating a lot of friction and heat.

    If the oil is too old, it will have built up high levels of particulates that may have clogged the oil filter. A clogged oil filter will not let oil pass through as it should, and this can affect the engines ability to maintain consistent speed. It may not be a hard sputtering, but you should be able to notice it as youre driving. A simple oil and filter change can go a long way towards ironing this out.

    Using An Oil Extractor Pump

    If you have a well-equipped home garage, you may have oil pumps.

    If you decide to go down this route, youll also need these items:

    • An old rag or towel.
    • One clear container .
    • Gloves .

    Step 1

    Allow your engine time to cool off if you were driving. Warm oil is fine to work with, but it shouldnt be boiling hot. Put your gloves on if you want to keep your hands from getting dirty.

    Step 2

    Pop the hood of your car and take out the dipstick. Place it on the rag or old towel to protect surrounding surfaces from stains.

    Step 3

    Set up your extractor as per manufacturer instructions. Connect it to a power source and prepare the tubes and drainage container.

    Step 4

    Insert the extractor tube into the dipstick tube. Power up your machine and keep a close eye on the container.

    Once enough fluid has been removed, switch off the machine. You may want to check the fill line every so often to make sure you havent removed too much.

    Step 5

    Once youve checked the oil level and it has returned to normal, disconnect the extractor. Replace the dipstick, and you should be good to go.

    Maintaining Your Lubrication System

    To keep your engine in proper working order, you need to maintain the lubrication system. This means changing the oil and filter as recommended in your owners manual, which is usually every 3,000 to 7,000 miles. You also must use only the grade of oil that is recommended by the manufacturer. If you notice any problems with your engine or an oil leak, you should have your car serviced with high-quality Castrol oil by mobile technician from YourMechanic right away.

    Trust The Car Oil Change Light If You Have One

    Some vehicles have an oil change reminder light that turns on when youve reached a set mileage. Those systems dont take your driving habits into account. So you have to adjust your oil change intervals according to how you drive. However, oil-life monitoring systems do track your driving habits. The computer records the number of cold starts, ambient and engine temperatures during startup, driving time between starts, engine load and whether the miles are highway or stop-and-go. It runs that data through an algorithm to estimate the remaining oil life. If you do a lot of short-trip city driving, the light will come on sooner than if you make long commutes.

    You can trust the carmakers oil-life monitoring systems only if you use the recommended oil and dont use any aftermarket additives. Pour in some miracle oil stabilizer and all bets are off.

    What Happens If You Put Too Much Oil In Your Car When Is It A Problem

    A millimeter or two over the fill line shouldnt be anything to panic over, especially if this only happens once in a blue moon. On the other hand, several inches above the fill line is something to worry about.

    A quart or more of unneeded motor oil in your car is a cause for concern.

    Heres what could happen if you keep driving with an overfilled reservoir:

    What Happens If You Run Out Of Oil

    Its important not to let your engine oil level get too low.

    With low oil pressure, theres less lubricant for the bearings and other moving parts in your engine. Metal rubs on metal, quickly causing irreversible and expensive damage.

    If the oil level drops too far, you might see the oil pressure warning light come on when you’re cornering.
