Engine oil improves sealing, prevents rust on various engine components, keeps engine parts clean of sludge, cools the engine system, and reduces friction between mobile parts in your engine system. Transmission fluid, on the other hand, helps your automatic or manual transmission run smoothly.
The primary difference between these two fluids is that engine oil functions are directed to the engine area that is responsible for combustion. Transmission fluid, on the other hand, lubricates your vehicle's transmission system, making it easier for your clutches and gears to engage.
Is it possible for engine oil to harm a transmission system if one of these fluids is mistaken for the other? Of course, the easy answer.
Is it permissible to use engine oil as a transmission fluid?
Engine oil and transmission fluid are both necessary fluids for the engine system of your vehicle to function properly. The engine oil is used in the engine, whereas the transmission fluid is used in the steering and gear system. Despite the fact that these two fluids are similar, can I use engine oil as a transmission fluid? The simple answer is no. Don't even consider it.
Many people mix up these two types of fluid and use them incorrectly in their vehicles, causing severe engine damage. Consider this for a moment: if these fluids can be easily interchanged, there isn't much reason to produce both of them. Only one fluid is required. However, this is not the case.
If you have, please contact your professional car mechanic at the car service in Reading and have this resolved as soon as possible to avoid total engine or transmission failure.
This guide was created to help you understand the differences between engine oil and transmission fluid, as well as the proper system in your vehicle to use these fluids.
Engine Oil vs. Transmission Fluid
The following are 6 differences.
1. Function
Engine oil functions in the engine system, reducing friction between moving components and keeping the engine system free of rust and sludge.
Automatic transmission fluid (ATF) is essential in the transmission system of a vehicle. This fluid keeps the system's gears and clutches running smoothly.
2. Consumption rate
Engine oil degrades over time and as a result of mileage. Always check the oil in your vehicle before starting it. Transmission fluid does not degrade as rapidly as time or mileage. A low transmission fluid level in such a short period of time is unusual. If you notice this, you should immediately inspect your system for leaks or look for full car service near me online and leave it to a professional.
3. Colour
When new, engine oil is usually golden or bright yellow, but it turns black after a while. The majority of fluids are red in colour.
4. Lifespan
Depending on the oil type, you should change the engine oil every 3000 to 6000 miles. If the oil is left for an extended period of time, its properties will deteriorate. Make it a habit to change your engine oil on a regular basis.
This fluid does not need to be changed on a regular basis, and it can go longer between changes. Please consult your owner's manual.
5. Detergents
A significant number of detergents are present in engine oil. Transmission fluid contains a high concentration of detergents because they work in a more contaminated environment.
6. Viscosity
Engine oil is viscous and designed to withstand high temperatures and pressures.
Transmission fluid has a lower viscosity and is designed to work at lower temperatures and pressures.
What Happens If I Use Engine Oil in Place of Fluid?
You will experience any of the negative effects listed below if you mix engine oil and transmission fluid. The amount of engine oil used and the length of time the vehicle was driven with the incorrect fluid, on the other hand, determine the extent of the damage:
1. Grinding sensation in gear
As the ATS is designed to work smoothly with the recommended fluid, replacing it with something completely different, such as engine oil, can harm your transmission system. As a result of damaged seals or O-rings, you will notice grinding or shaking movements when changing gears.
2. Car will not go into gear
When there is engine oil in your transmission system, you will notice a delay in your vehicle's response while in gear, or the transmission may not function when you position it in reverse or drive. This is because engine oil's properties cannot replace the functions of transmission fluid in your system.
3. Gears slipping
Gear slipping is another issue you will face if you are a victim of this incident. If this happens, it is a serious safety issue, and dealing with your transmission system shifting gears while driving can be terrifying. This is caused by faulty transmission fluid in your vehicle's system.
4. Burning smell
Detecting burning odours in your vehicle is not normal, and a common cause of this odour from your transmission system is overheated fluid in the transmission. Unlike engine oil, transmission fluid has a higher lubricating property, preventing any type of damage between meeting parts. Your transmission system will eventually fail if it is not properly lubricated.
5. Unusual noises while driving
When you drive your vehicle, the incorrect type of fluid in your transmission system will cause a variety of noises. When the fluid in your automatic transmission system fails to function properly, your transmission will make a variety of noises. The transmission fluid lubricates the mechanical gears and the entire system very well. The absence of this function will cause transmission system damage, resulting in noises while driving your vehicle.
6. The engine check light comes on (EML)
The transmission system is outfitted with numerous sensors that alert you if something is wrong with your transmission system. These sensors send signals to the computer system of your vehicle, alerting it to any problems. As a result, if you use transmission fluid in your system instead of engine oil, your engine check light also known as engine management light will illuminate.
How to Repair Engine Oil Related Transmission Issues
The ease with which you can solve this problem is determined by the time it is discovered. If you catch it early enough, it will only cause minor damage to your transmission system. You may only need to flush the engine oil from your transmission system if you added a small amount of engine oil to the transmission system. However, if you experience any of the side effects listed above, you should flush.
If you have the right tools, flushing the transmission system isn't difficult. You'll need transmission fluid, a funnel, and a bowl full of basic tools.
The first step is to pop the bonnet of your car. When working with any liquid in the car, disconnect the negative terminal of your battery to avoid shock. Now that you can see the transmission coolant lines underneath the car, lifting your vehicle may not be necessary. You are not required to do so if you do not wish to.
Make sure you have a bucket ready to catch the drained fluid when you disconnect the transmission lines. If you can't find your vehicle's repair manual, you can detach the two lines with the appropriate screwdriver types, place them both in a bucket, and one of them should spit out the fluid in the transmission system.
It's also worth noting that transmission oil and transmission fluid are interchangeable. You are not required to be perplexed by this.
The same amount of transmission fluid(TF) must be pumped into the system. Never flush your transmission with low fluid to avoid accumulating air bubbles in your lines, which is a recipe for disaster. You also don't want to drive with a low fluid level because it can cause the engine to shut down completely.
Insert your funnel into the transmission port and fill it with the necessary fluid. Remove the transmission deep stick. It is critical to note that the funnel in the transmission port must be constantly filled to ensure that there are no gaps for air bubbles. Then request that someone start the car for you.
Fill an oil gun with TF and connect the hose to the transmission port to allow the fluid to flow in without your intervention. It makes no difference, and you can use whatever you have on hand. As soon as the car starts, you will notice a high flow of fluid from the transmission lines. Turn your steering wheel to the opposite side to increase the flow. It is preferable to do this with the assistance of another person. Keep an eye on the fluid flow to see when it's time to stop the flush. When the fluid coming from the line resembles the TF poured in, it's time to replace it.
You can continue flushing for a while longer until your transmission fluid is a similar or nearly similar colour, and then stop. Please check the TF level and avoid overfilling as this will cause problems. You should empty the excess fluid if you did this. To avoid problems with motor oil in your manual transmission or automatic system, make sure you follow this guide exactly.
If you've been driving your car for hours with the wrong fluid, you should look for car repairs and tow it to a professional so that any damaged components can be repaired the system can be flushed.
Conclusion
Now that we have this guide, we shouldn't get any more questions about can I use engine oil for transmission fluid or can I use transmission fluid instead of engine oil? They are distinct and serve distinct purposes. As a result, keep engine oil and transmission fluid separate. To avoid dealing with unneeded issues, always use the proper fluid in your vehicle.
