We at PRIO believe that the future requires a more sustainable world. This is why we have created premium fuels to reduce CO2 emissions. But that is not all, our premium fuels also reduce consumption and improve engine performance.

The (Portuguese) government issued Decree-Law 6/2015 that made all filling stations sell basic petrol and diesel. 

We work every day to keep our prices down. Selling TOP products on large scale means we can keep our prices low.

TOP Diesel and TOP 95 Petrol are fuels you can and should use in your car. The products begin life just like the basic fuels, the TOP Diesel and TOP 95 get additives that ensure lower consumption and lower CO2 emissions into the atmosphere.

First off, TOP Diesel has greater lubricating properties, it reduces engine wear, the likelihood of breakdowns and reduces maintenance costs over the medium term. As it has a higher cetane number, it ensures more complete fuel combustion, more efficiency and engine performance and less white fume and engine noise. And greater power of course, along with lower consumption and less CO2 into the atmosphere.

There is nothing wrong with it. In fact, after the third tankful of TOP 95, you should start noticing a difference.

Don't worry: the additives we have developed meet all the European specifications. It is perfectly safe.

It is a multifunctional additive that improves the engine's performance in the key area of cleaning the injectors, cetane number, lubricity, corrosion and the formation of foam.
