The best car additives for gasoline engines

Suprotec Active Plus

Rating: 4.9

Suprotec Active Plus

The leader in the current ranking in the category of additives for gasoline engines becomes a composition from SUPROTEC, providing the most strong positive effect on engines in pristine or in satisfactory working condition. Get Active Plus for a car that is already living its age will be expensive and inefficient: processing with additives is unlikely to pull him out of critical or limit state. But to work in a pretty “live” it’s perfect for the machine: here you’ll get about 3-4% savings fuel, and a significant increase in power due to softness and smoothness of work of rubbing parts (by 3.2%), and increased working resource even with rare use of the composition.

In this case, only one fact is upset: the introduction of SUPROTEC Active Plus in the engine takes place in two stages. On the first gut the motor is washed for a period of time, the spent liquid is drained, and the second should be full filling with a new portion of oil for long-term work. By the way, such a measure is enough for 50 thousand kilometers, which proven in field tests on a real car (not on stand). Yes, let it be expensive, and let it have a little confuse, but the positive effect is definitely worth it.

Advantages

  • works great in used and brand new engines;
  • valid for 50 thousand kilometers;
  • a significant increase in the performance of gasoline engines: reduced fuel consumption, noise and vibration, increased power;

disadvantages

  • two-stage processing;
  • high cost (for the first filling you need two bottles additives).

RVS Master

Rating: 4.8

RVS Master

This tribotechnical composition is often opposed SUPRATEC Products – Online Forums Consumers whole scandals are fanned and serious battles are being fought. We will do more wisely – both products are equally good in their business. Yes, in terms of improving the performance of RVS engines Master is slightly inferior to its opponent – emphasis in the proposal should be done on the word “a little bit.” For example, fuel economy will be about 2.9%, and capacity will increase by 2.5%. But there is in this product and a number of very strong points that SUPRATEC Active I could not overpower.

It’s about the possibility of using the RVS Master with very old engines on the verge of the last breakdown. And the effect from application will be tantamount to gradual technical service. What do we mean: composite ceramic-metal the composition of the additive has a directed effect on the surface parts, forming a wear-resistant protective layer with a low coefficient friction. Thus further frictional impact on the base metal, which gives the elements of the engine last longer (approximately 40-50 thousand kilometers). Another plus: processing in one fill, eliminating any problems with dosage and re-introduction of the additive into the oil.

Advantages

  • recommended for use with worn engines;
  • has an excellent restorative effect on the surface details;
  • the effectiveness of the action persists for 40-50 thousand kilometers;
  • does not require two-stage filling.

disadvantages

  • fairly high price;
  • slightly less pronounced increase in performance engine than the main competitor.

Liqui Moly CeraTec

Rating: 4.7

Liqui Moly CeraTec

One of the few advanced formulations to protect the engine from the harmful effects of temperature, friction and chemical impacts by forming on the surface bound ceramic layer. In addition, Liqui Moly CeraTec has incorporated a complex of organic components with molybdenum ions, which characterized by high strength and serves to fill microcracks and unevenness on the surface of parts in friction units.

It’s a joke, but the residual working state of the fill is observed and with a long (by the standards of additives) mileage of vehicles: according to experts, approximately within 30-35 thousand kilometers. The use of Liqui Moly CeraTec has a positive effect on fuel consumption indicators: through laboratory tests it was proved that the average decrease in gasoline consumption is in 1.8-2.4% average (depending on engine condition and model auto). There is an increase in power (insignificant, in the region of 1%), and also increases the resource of the motor. The only problem: worth it tribological composition is expensive, especially because of the need its continuous use.

Advantages

  • a significant increase in the engine’s working life in the long-term run;
  • increased power and reduced consumption fuel;
  • action enhanced by the addition of ceramic components and molybdenum.

disadvantages

  • high price.

SMT Oil Treatment

Rating: 4.6

SMT Oil Treatment

Perhaps the cheapest way to protect your motor from wear is purchase this additive. It is found in the market enough rarely, but provides a complex of positive effects not smaller than, say, an upstream RVS Master or chemistry from SUPROTEC.

According to the manufacturer, SMT Oil Treatment reduces oil and fuel consumption, reduce smokiness by contributing to complete burnout, increase compression (which is very important for worn motors) and provide a power increase. By repeatedly conducted bench tests all these statements were justified: the complex really works as prescribed, either otherwise, performing all the functions superimposed on it. Another thing is that in the exploitation of this difference is almost imperceptible: an increase in some and other parameters decrease in tenths of a percent, and sometimes it doesn’t differ at all from permissible errors measurements.

In general, we can conclude that SMT Oil Treatment is a composition really good. Though not as effective as that describes the manufacturer, but it’s definitely not harmful to the engine will be able.

Advantages

  • very low price;
  • a slight increase in engine performance in terms of power and fuel consumption;
  • improved lubrication processes.

disadvantages

  • all effects are not expressive in real operation.
