It’s no secret that engine knocking can be a problem for many drivers. It is also not uncommon to hear people say that thicker oil will solve the problem. Is this true, or does it only work in movies?
Will Thicker Oil Stop Engine Knocking? Thicker oil won’t stop engine knock, but it can temporarily alleviate the symptoms. Getting rid of knock requires a proper tune. You may experience rod knock or piston slap, which can get picked up by the knock sensor but thicker oil would only put a bandage on serious problems.
Engine knock is caused by a number of factors, including fuel octane levels that are too low or inconsistent. It can also be caused by spark knock due to the ignition timing being off. All these scenarios will need to be addressed in order for engine knocking to stop and make sure it stays stopped.
You may have heard that a “knock”, or the sound of air-fuel mixture burning improperly, is common in cars. A knock can be caused by many different things; from improper fuel ratios to faulty parts and more! The danger comes when these knocks continue unabated over time as they can cause engine wear and damage other regions (aka: not just your pistons) if left unchecked. So it’s important you go ahead with a fixer-upper ASAP rather than wait for something worse to happen down the road so you don’t end up paying even more money on top of what could’ve been avoided.
What’s the deal with my engine knocking at idle? If you hear engine noises like knocking or tapping, it could mean your vehicle is low on oil.

At idling, the engine makes a knocking noise.
How do I get my engine to quit knocking?
- The first step in attempting to resolve engine banging is to switch to higher-octane gasoline.
- Replace your spark plugs and wires as part of your engine’s tune-up.
- Replace your vehicle’s oil on a regular basis and keep an eye out for low oil levels.
What causes banging in an engine? The knocking sound generated by an improper air-fuel combination can cause significant damage to the piston and cylinder wall. A lack of oil in the upper cylinders head area will also generate a knock that must be corrected before it becomes too severe, which is why checking your engine for such problems at routine intervals is crucial!
Engine Knocking: Will Thicker Oil Help? – Related Questions
Is heavier oil going to stop the engine from knocking?
