Knocking an engine is one of the most common complaints of people with their cars. People who own vehicles often find themselves with the noises the engines create. At times, the machines make noise that sounds like a roar. What causes these noises?
The engine knocking occurs when the fuel doesn’t burn evenly in the engine’s cylinder. That raises a question – will thicker oil stop engine knocking?
If the cylinders keep the proper balance of fuel and air, fuel tends to burn in tiny and organized pockets instead of all at once. It creates a shock and triggers the next pocket. This is how it continues the cycle along.
Are you wondering if thicker oil may stop the knocking of an engine? We will discuss the benefits of using more viscous oil and other alternatives to help stop engine knocking.
What are the causes of engine knocking?
There are a few probable causes that lead to engine knocking. Some of them are listed below:
The fuels of almost any vehicle have a carbon cleaning detergent. They don’t usually prevent the formation of carbon deposits. Fuel burns when it mixes with oxygen. Diesel and gasoline contain many carbon molecules.
The residue of carbon tends to form on valves, spark plugs, and all other segments during the process of combustion. This is how the number of compression increases. It also reduces the amount of volume inside the cylinder.
The fuel you use, if it has a low octane rating, you can expect a knock. The octane rating measures the fuel’s ability to prevent the fuel-air mixture’s premature detonation in the engine.
This combustion is the foremost reason for knocking you seem to hear. The octane rating must maintain a good score so that the knocking does not occur. Low-rated octane causes severe damage to the vehicle engine.
Malfunctioning Spark Plugs
Spark plugs generate the electric spark that inflames the fuel-air mixture. Spark plugs get your engine up and running. Similar to other parts in a car, the spark plugs also get inefficient over time.
The longevity of a spark plug depends on its condition. Automobile companies recommend installing new spark plugs occasionally. After covering a significant number of miles, you may require a new spark plug.
Will Thicker Oil Stop Engine Knocking?
Adding heavier oil temporarily helps with noisy engines. But it does not solve the actual underlying problem, which includes rod noises, lifter noises, and many more.
Oil additives help in these particular cases. Using thicker oil is quite beneficial for vehicle owners as it helps stop engine knocking. Better to use more viscous oil than other available oils.
There are a few alternative methods that you can use to lower the engine knocking. Some of those viable alternatives are mentioned below:
High Octane Rating Fuel
The quality of the fuel is the prime criterion for stopping the engine knock. The fuel must ignite at the right moment during the combustion cycle. To know about what octane rating fuel you should use, have a glance at the owner’s manual. You can choose to use an octane booster.
They are designed to help increase the octane level of the fuel. Always remember to check the octane rating and keep it high.
Cleaning Combustion Chamber
Try to clean your cylinder occasionally. Sometimes the wrong fuel can cause knocking as it might not ignite at the right moment. Therefore, it leaves excess contaminants in the cylinders.
Fuel additives are good options for cleaning your cylinders. The top gasoline brands usually help provide extra detergents that keep the engine clean. Just buy a fuel additive and splash it into your gas tank at your next fill-up.
If the detergent cannot stop the knocking, the other alternative is to use engine flush. The engine flush gets rid of the carbon deposits and keeps them out from the system. A clean cylinder helps keep the car healthy.
Car’s Timing Check
Locate the engine’s timing mark. It is in that small gap in the transmission bell housing. Look for the opening with marks that are close to it. It might also be seen as covered with a rubber cap. It helps keep the dirt out of the bell housing.
Find the first spark plug. That is the one you should use to check the timing of the engine. If you are not sure about which one it is, try reading the owner’s manual. Also, make sure to set up your park brake. The car should be parked with safety so that it does not move when you are working.
Turn your engine on and let it warm up before checking. That is how you can yield the most accurate results. Now connect the timing light to the first-marked spark plug wire. Attach the lead to the plug wire; after that, turn on the light.
The readings will be wrong if it is not the first spark plug. Take records of the numbers and combine the results of the timing test for interpretation. If the timings are adjusted, there will be no more knocking on the engine.
The question was, will thicker oil stop engine knocking? The answer is yes, and some additional options that help stop the knocking of the engine. If you want to control the machine, it is preferable to try all the available suggestions. It might feel like a hassle for the first few times, but worth it. In the long run, the vehicle will still be performing like a new one.
That’s a plus point as you won’t have to switch cars over time. You can also keep the vehicle as a collectible. Also, to remind you again, it is better to use oil additives with thicker oil.
Precisely, the performance of the vehicles smoothens with oil additives and engine flush. More viscous oil can be a pretty helpful material if you want to stop the engine from knocking. Hope you had an informative read, and thanks for reading till the end!
