Keeping your car’s engine always ready does not have to require going to the mechanic. Prevention is better than cure so that problems do not escalate.
Updated February 14, 2023. We’ve written a new lead, selected new products, and changed links and photos.
Do you want to improve the performance of your vehicle’s engine? Do you want to clean the injectors? Get the engine to make less noise than before? You don’t have to make an appointment at the workshop: you can do it yourself with different products and additives on the market.
However, you have to know which are the recommended products and which are not. Also, each one has a different function. For this reason, we have selected the best products, additives and liquids to clean and improve engine performance, something key to always having your vehicle ready and ready inside. Of course, do not forget to also tune it on the outside.
You can even find some of the best products to pass the ITV with your car without problems on Amazon. Here is a list with recommended brands so that the state of your engine does not deteriorate. They are an investment in peace of mind that can also save you a lot of money.
- Injector Cleaner: Liqui Molly
- Engine Oil Treatment: Wynn’s
- Injector cleaner + Pre MOT: STP
- Air filter cleaner: Motul Mccare A1
- Anti-friction wax for engine oil: Liqui Moly 3721 Cera Tec
Injector Cleaner: Liqui Molly
Injector Cleaner: Liqui Molly
It is a classic. Either due to ignorance of the user or even of the mechanic himself, when the engine goes badly, the same thing is always used: “there may be dirt in the injectors”. Luckily, confirming if this is the case is not too expensive: you can solve it with an additive for cleaning the injectors.
We recommend this one from Liqui Molly. In 300 ml format it would be enough for up to 70 liters of fuel. It is suitable for gasoline engines: you put it in with at least half a tank of fuel and drive about 100-200 kilometers at high revs.
Engine Oil Treatment: Wynn’s
Engine Oil Treatment: Wynn’s
The stress generated in the components of the car due to adverse weather conditions, the pollution of urban centers and the typical type of driving in the city lead to wear on the motor oil that causes it to lose part of its lubricating properties.
This Wynn’s motor oil treatment is perfect for cases in which we detect that there is high oil consumption in our vehicle and that it is not due to a loss of oil. In addition, it will help you reduce exhaust fumes, improve engine performance and reduce noise.
Its objective is to increase pressure and reduce friction and it achieves this by increasing the viscosity index of the oil itself. The ideal is to use it shortly after having made an oil change so that the result is ideal.
Injector cleaner + Pre MOT: STP
Injector cleaner + Pre MOT: STP
And we come to another of the classics that combines the first one that we have talked about with a Pre ITV treatment whose objective is that we manage to comply with the minimum requirements demanded in the technical review.
STP is a pack of two products with which we should reduce particle emissions and thus manage to pass the ITV test. Of course, it is not miraculous, and it will not get your vehicle to go from zero to a hundred faster, but it can be a good option if you detect that since the last ITV the car has started to smoke more, and you fear that it will not be able to pass the test.
Also, keep in mind that the tests are becoming more and more strict with respect to particulate emissions, so it is becoming more and more essential that your car has an efficient operation. You have it for both diesel and gasoline mechanics.
Air filter cleaner: Motul Mccare A1
Air filter cleaner: Motul Mccare A1
The air filter ensures that the air entering the engine is clean, or at least as clean as it can be. It is obvious, therefore, that its objective is to retain dirt from the air. The older the filter and the more used it is, the more dirt it will have, and this can have two consequences. One is that it is no longer able to hold and then dirty air enters the engine. The other is that it acts as a barrier, and directly does not enter enough air into the engine, so that there cannot be proper combustion.
This air filter cleaner kit is a good option to restore the optimal condition of the filter: it effectively removes dust, mud, sand and oily residues.
Anti-friction wax for engine oil: Liqui Moly 3721 Cera Tec
Anti-friction wax for engine oil: Liqui Moly 3721 Cera Tec
It’s simply the #1 best seller in motor oil additives. We are talking about Cera Tec and its different variants. It is a ceramic-based solution that is responsible for reducing friction between metallic elements.
In essence, that is the function of engine oil, but this additive improves the performance of the lubricant by reducing the friction index, prolonging the useful life of our engine, and also helping to reduce fuel consumption by optimizing the efficiency of the motor unit. In addition, it is suitable for mixing with all commonly used oils.
