Engine cleaner at a glance

  • With engine cleaners, a distinction is made between so-called cold cleaners for use in the engine compartment and engine flushing, which is filled in via the engine and cleans or optimizes the engine from the inside.
  • Engine interior cleaner is available as a spray or in liquid form. The latter is available in a pump spray bottle or in a canister, the contents of which can then be sprayed with a spray gun.
  • While the cold cleaner cleans the engine and the engine compartment of oil and grease contamination in conjunction with dirt, the engine flushing cleans and loosens deposits on injection nozzles and intake valves and protects them from corrosion. They are available for the tanks of gasoline or diesel engines or for the oil circuit.

Cars that they maintain are superior to others

Which engine cleaners are the best?

Engine cleaner is not just engine cleaner, because the engine can be cleaned from the outside in the engine compartment and from the inside in the engine housing. Both are very different processes that we would like to explain to you below. The manufacturer names are not always meaningful, sometimes they talk about motor clean or motor system cleaner, others about universal cleaners or cold cleaners. Most of all you can do something with the term engine compartment cleaner.

Engine cleaner note:

Therefore our well-intentioned note: It is essential to read the small print so that there can be no mix-ups.

The cold cleaner engine wash

Even if your car comes out of the wash and shines on the outside, it is still a long way from clean, because neither the interior nor the engine compartment are cleaned. While most still have one Car interior cleaner use and vacuum thoroughly or a Cockpitspray apply, a look is seldom devoted to the dirty engine compartment. There is dirt here, too, and not too scarce. Oil and grease residues have mixed with street dirt and cover all hoses, assemblies and the entire interior body space. None come here Car brush a cold cleaner must be used here, which is called Engine cleaner spray, Pump spray or spray on with the spray gun. This is used to spray the engine compartment, which, by the way, is the same with other machines or tools or as Motorcycle engine wash goes. Short exposure time and everything is freed from stubborn dirt and oil residues, spray off - done. Some engine cleaners also contain a preservative that acts as a protection against corrosion.

Engine cleaner note:

Since oil residues are removed when washing the engine, you should carry out the work using an oil separator, for example in a washing box at the petrol station.

The engine flush

Your engine also needs an "engine wash" on the inside from time to time, which keeps it clean and cared for from the inside. Two different methods are used for engine flushing. Either the engine flush is added to the tank contents or added to the engine oil before the oil change.

Engine cleaner for the oil circuit

Engine oil ages, forms combustion residues or is contaminated by material abrasion. This contamination is deposited on the piston rings, on ring grooves, oil holes or bearings. The engine has to use more and more energy over time and accordingly consumes more fuel, not to mention the poor exhaust gas values, which in the worst case can lead to the TÜV badge not being issued. In the worst case, the fine ducts that are used for on-site lubrication can clog and their failure can lead to major engine damage. Especially when buying a used car, you usually don't know whether the maintenance intervals have been adhered to and which oil has been used. An engine flush should be carried out before the upcoming oil change, especially if the mileage is high.

Engine cleaner note:

An engine flush for the oil circuit should only be done by those who are familiar with it. For all others, it is advisable to have a rinsing performed in a specialist workshop.

Engine cleaner for the oil circuit. Engine washing advantages / disadvantages

Benefits

Dissolves combustion residues in the engine

keeps the channels free for lubrication

especially recommended for high mileage

easy to use before an oil change

Disadvantages

Drained oil is hazardous waste

Keep your receipt, then your used oil will usually be taken back from the seller

System cleaner for gasoline or diesel

The fuel system can also be made more efficient for combustion in the engine. No additives are added to increase performance, but rather as cleaners that clean the fuel-carrying components. Deposits on valves and injection nozzles, on the high pressure pump or on spark or glow plugs are loosened. This is noticeable later in the throttle response, fuel consumption and exhaust gas values. These engine cleaners are simply added to the tank contents, but beware of petrol and diesel engines, there are different products.

Engine cleaner note:

Before every trip abroad it is necessary to use one Car engine cleaner cheap, because high-quality fuel is not always available on the way, which can add even more to the fuel system. A system cleaner should therefore be used in this case.

Benefits

Simply fill into the empty tank and fill up normally

Recommended if poor quality fuel is available

Our engine cleaner purchase advice

Please never blindly Buy engine cleaner, because that can go badly in the pants. Especially with articles like the Sonax or Liquid Moly engine cleaner, which have countless care products in their range, you can quickly make a mistake. So you should do the following Engine cleaner purchase recommendations pay closer attention so that there is no bad buy. First of all, you should ask yourself which engine cleaner is actually needed:

  • Cold cleaner

The cold cleaner is right for cleaning the engine compartment. It is available as a spray or a pump spray. So you can easily apply it. Most products have good creeping properties. Depending on how dirty it is, leave it on for a few minutes and then rinse off with clean water. Caution, do not spray on hot parts!

  • System cleaner gasoline or diesel

The system cleaner gasoline or diesel is added to the fuel system. This works best when the tank is almost empty. This is the best way to judge how much cleaner is needed for the contents of the tank. Most system cleaners are supplied with a filling aid, which makes it easy to fill in on the go. An additional bottle for traveling abroad can do no harm if only inferior petrol or diesel is available there.

  • Engine flushing for the oil circuit

When flushing the engine for the oil circuit, it should ideally be carried out the next time the oil is changed. An oil-sludge rinse can be carried out, especially on older cars with high mileage that have never been flushed. Anyone who does not trust themselves should go to a specialist workshop.

Answers (FAQ) to the engine cleaner comparison

Unfortunately, there is no engine cleaner test report from Stiftung Warentest. Motor cleaner test winner can be found in Auto & Bild or in the ADAC newspaper.

Engine cleaner experience reports have shown that you should flush the engine of engines that have already had a long service life or when you buy a used car where you are unsure when and how often an oil change was made.

A cold cleaner engine wash is an engine compartment wash. Here the engine compartment is cleaned with the engine, radiator and all elements surrounding them.

The engine flushing oil circuit is used together with engine oil and cleans everything that has to do with the oil circuit in the engine. The system cleaners for diesel or gasoline are added to the tank as an additive and clean the parts in the engine that come into contact with the fuel.

The engine cleaners are used externally for the engine compartment, the motorcycle engine or to clean other parts that are contaminated with grease and dirt. System cleaners, on the other hand, clean the fuel areas of the engine and the engine flush is used in the engine's oil circuit.

Engine compartment cleaners clean everything that is under the hood. An engine flush is usually carried out on older vehicles that have already had a lot of abrasion, soot or the like. They are available both for the oil circuit and as a fuel additive.

An engine flush should be carried out shortly before the oil change. Pour in the agent at operating temperature and let it run idle for about 10 minutes. Then drain the used oil and fill in new one. Always follow the manufacturer's instructions.

Even if an engine cleaner is considered biodegradable, that's only partly true. You should therefore use a washing box at the gas station that has an oil separator when cleaning the engine compartment.

Conclusion on the Moror cleaner and the engine system cleaner

It is advisable to always use an engine compartment cleaner and, in older vehicles, to use a system cleaner or an engine flush in the oil circuit. With the former, the dirt in the engine compartment is removed, with the other residues in the engine itself. However, any type of engine cleaner can only clean and prevent, but do not repair what is broken!
