What is an Engine Flush?
An engine flush is a liquid solution designed to remove dirt, grime, and contaminants from the engine’s oil system. It’s typically used in conjunction with an oil change, and its purpose is to clean out the engine’s passageways, pistons, and cylinders, allowing for a fresh start with new oil.
Why Use an Engine Flush?
There are several reasons why some mechanics and car owners swear by using an engine flush before an oil change:
- Removes built-up contaminants: Over time, engine oil can become contaminated with dirt, dust, and other debris. An engine flush helps remove these contaminants, allowing for a cleaner start with new oil.
- Improves engine performance: By removing built-up grime and debris, an engine flush can help improve engine performance, including increased horsepower and better fuel efficiency.
- Extends engine life: Regular engine flushing can help extend the life of the engine by preventing corrosion and wear on moving parts.
- Prevents oil sludge buildup: Engine flushing can help prevent the buildup of oil sludge, a thick, gooey substance that can clog engine passageways and cause serious damage.
When to Use an Engine Flush?
Not every car or engine requires an engine flush before an oil change. However, there are certain situations where an engine flush may be necessary:
- New engine or recent engine rebuild: If you’ve recently replaced or rebuilt your engine, an engine flush can help remove any debris or contaminants that may have accumulated during the process.
- High-mileage engine: Engines with high mileage may benefit from regular engine flushing to remove built-up contaminants and debris.
- Engine oil change interval: If you’re changing your engine oil more frequently than recommended, an engine flush may be necessary to remove any built-up contaminants.

- New oil filter: If you’re installing a new oil filter, an engine flush may not be necessary, as the new filter will help remove any contaminants from the oil.
- Low-mileage engine: Engines with low mileage may not require an engine flush, as they’re less likely to have built-up contaminants.
- Engine damage: If your engine is damaged or has been neglected, an engine flush may not be enough to restore it to its former glory. In these cases, more extensive repairs may be necessary.
How to Use an Engine Flush?
Using an engine flush is relatively straightforward:
- Drain the old oil: Start by draining the old oil from the engine.
- Pump in the flush: Use a pump or a turkey baster to pump the engine flush into the engine.
- Let it sit: Allow the engine flush to sit in the engine for the recommended amount of time, usually 5-10 minutes.
- Pump out the flush: Use the same pump or turkey baster to pump out the engine flush from the engine.
- Change the oil filter: Install a new oil filter to ensure the engine is protected from contaminants.
- Change the oil: Finally, change the oil with the recommended type and amount for your engine.
Conclusion
In conclusion, whether or not to use an engine flush before an oil change is a personal preference and depends on the specific situation. While some mechanics and car owners swear by the practice, others argue it’s unnecessary and potentially harmful. By understanding the pros and cons of engine flushing, you can make an informed decision about whether or not to use an engine flush before your next oil change.
