How to Clean a Funnel After an Oil Change? Get The Facts!

Though it may not seem like a big deal at first, but cleaning your funnel after an oil change is crucial for keeping your car running safely and efficiently.

Let’s start by saying that, Funnels are designed to transport lubricant from a large container into an engine’s small opening. However, they may also introduce contaminants into the lubricant and affect performance over time.

How to Clean a Funnel After an Oil Change?

The first thing we recommend doing is to pour the cleaning solvent on the funnel. Then give the cleaning solvent some time to be mixed with the oil inside the funnel. After a couple of minutes, you can go ahead and wash the funnel with fresh water and wipe it dry with paper towel or a piece of cloth. Now, it is safe to say that your funnel is ready to use.

Why Funnel is Important to Clean After Oil Change

How to Clean a Funnel After an Oil Change

Funnels are tubes or pipes with a wide mouth that guide liquid or powder into an opening. Commonly used in laboratory settings, these can be constructed out of stainless steel, aluminium, glass or plastic.

A funnel is essential in the automotive industry, as it permits fluid transfers between containers without creating a mess. It’s especially useful when adding or draining transmission or coolant fluids that could spoil your engine bay if they spill.

Before beginning your next oil change, make sure to take the time out to clean the funnel thoroughly. Doing so will prevent clogs in the filter and damage to your car’s engine.

Should I Reuse An Oil Funnel?

Reusing an oil funnel is usually not necessary unless there’s no alternative. But if it becomes necessary, make sure to clean it thoroughly after each use.

The reason for this is because funnels can easily become contaminated with dirt and other particles during use. This could lead to a buildup of contaminants that is detrimental to the engine, potentially even damaging it completely – resulting in costly repairs.

One way to prevent this from occurring is using a sealable and reusable (S&R) container for fluid transfers. S&R containers tend to offer the main benefit of restricting how much dirt can enter into your machine.

Another thing we recommend is to use different funnels for each fluid or oil type. Doing this ensures each lubricant goes through its own funnel and doesn’t mix with any other fluid or oil. In the long run, this could save you a considerable amount of time, money and hassle.

How to Avoid Sludge Formation on the Engine

Engine oil that has become oxidized breaks down and mixes with contaminants to form a sticky sludge. This sludge contains partially burned fuel, metal fragments, dirt and liquid coolant.

Sludge that blocks an oil screen siphon or prevents proper lubrication can cause serious damage to your engine. Not only that but it could even plug pressure sensors in valves, decreasing efficiency and raising maintenance costs.

It is safe to say that sludge formation can be caused by several factors, including driving under extreme operating conditions and excessive temperatures. On the other hand, sludge may also form naturally when an engine runs for extended period of time under normal operating conditions and temperatures.

To prevent sludge formation in your car’s oil, it’s best to follow the manufacturer’s recommended oil change intervals and use only high-quality oils that meet or exceed OEM specifications. However, it is best to keep in mind that synthetic oils tend to be much more resistant to sludge formation than their non-synthetic counterparts.

Things You Need to Clean the Funnel

When performing an oil change, it’s essential to take the time to clean the funnel. Doing so will guarantee your filter remains free of dirt and debris, helping your engine run smoothly and efficiently.

Before you start the process of cleaning your funnel, there are a few items you’ll need. First, we recommend getting yourself some paper towels and cleaning solvent.

Additionally, you’ll require a funnel brush or vacuum cleaner which you will use to clear away any obstructions on the funnel. These tools make the cleaning process much smoother and more efficient.


When it comes to cleaning a funnel we always think it is best to use a water-soluble degreaser to get the job done. You should not use a regular cleaning agent such as soap or detergent to clean the funnel because these product will not be able to remove grease from the funnel.
