Frequently Asked Questions

What is the natural color of diesel?

The natural color of diesel is dark yellow, but its intensity can vary depending on the source, refinement, time in storage and handling.

According to the American Society for Testing and Materials (ASTM), although the specification for the color of diesel is 3.0, this does not determine the quality of the product.

Is green diesel better quality?

No. Neither green nor any other color improves the quality of the fuel, as the original additive is clear.

Why is there sometimes a sediment or dreg in the cistern when I load diesel?

The sediment is a mixture of dead microorganisms, of their waste and of decomposed product. Diesel, being an organic product, is food for bacteria and fungi that comes through water. Keeping the cisterns, the storage tanks or the cylinders free of water will prevent the formation of sediment in the fuel.

Is it normal for the diesel to generate foam?

Yes, it’s normal, but its permanence may be reduced using additives. PETROPERÚ has antifoam additives for diesel.

Should diesel and gasoline/gasohol be mixed?

No. The diesel engine, also called an oiler, should only use diesel, and the gasoline engine should only use gasoline/gasohol. Both engines have entirely different designs and using a fuel for which they weren’t designed will cause them grave damage.

Will the vehicle work better if I fuel it with a higher octane gasoline/gasohol? For example: gasohol 97 instead of gasohol 90.

No. The gasoline engine is designed for the octane according to the compression relationship of the vehicle. The operation of the engine will be optimum according to the octane indicated in the vehicle manual, which can be expressed in RON (Research Octane Number, used in Peru) and AKI (Anti-Knock Index, used in the United States). In both cases, gasoline/gasohol of the same or higher octane of the different grades that PETROPERÚ offers to the market should be used.

Why does gasoline/gasohol have different colors?

Gasolines/gasoholes are oil derivates, which may have lighter or darker tones. That’s why gasoline/gasohol changes its natural color to a darker one, and may vary in tone when the colorant is added. For example, gasohol 90 may vary from dark pink to violet or light brown.

How can I quickly determine that the fuel has optimum quality conditions?

It’s enough to carry out a visual inspection of it: It must have a clear and bright appearance. If the fuel is seen to be opaque or murky, it probably contains minimum amounts of water which are not enough to achieve the correct separation of the fuel (two phases).

What happens to gasohol when water mixes with the fuel in the storage tank at the service station?

Alcohol in the gasohol migrate to the water phase and causes the gasohol not to have the optimum content indicated in the national regulation: 7.8% vol. This situation warrants a fine from the Regulatory Organism in Investment in Energy and Mining (Osinergmin).

What happens if water comes into the fuel tank of the vehicle from the service station or through the use of inadequate fuel lids?

The entrance of water into the fuel tank removes the lubrication from the engine and allows for premature oxidation of the entire combustion system. Also, generates obstruction in the lines, dirties the fuel filter, unbalances the engine connecting rods and destroys the injectors.

How can the water enter the storage tanks and produce the contamination of the product?

Underground water can filter in through cracks and fissures in the old tanks. Also, rainwater can filter in through cavities or poorly applied coatings in the pipes.

Do the PETROPERU fuels have additives?

Our fuels contain multifunctional performance additives, which have as main objective to preserve engine cleanliness by optimizing the use of fuel and generating lower maintenance costs.

Where does PETROPERU sell Diesel B5 S50?

The technical specifications of our PETROPERU DIESEL B5 S50 are in accordance with the current regulations, D.S. N° 092-2009-EM and its Errata.

 

Does Petroperu sell green Diesel?

Sí, actualmente desde las Plantas de Ventas Cuzco y Juliaca, comercializamos Diesel B5 S-50 de color verde con una dosificación superior de aditivo, que permite un mejor arranque del motor en climas fríos.

Why does sludge sometimes appear in the tank when I load it with Diesel?

The sludge is a mixture of dead microorganisms, waste of these and decomposed product. Diesel, because it is an organic product, is the food of bacteria and fungi, the same ones that reach the fuel through water. Keeping our tanks, storage tanks or cylinders free of water will prevent the formation of sludge in our fuel.

Is it normal for Diesel to generate foam?

Yes, it is normal, but the permanence of this can be reduced through the use of additives. Petroperu has anti-foam additives for diesel.

Do the Petroperu 95 and 97 Gasoholes have less tan 50ppm of Sulfur?

The PETROPERU Gasoholes have very low sulfur levels in their composition, even below the maximum level of the current valid specification. In relation to this, the Gasoholes of 95 and 97 octane that we commercialize in the whole country, through the more than 650 Service Stations affiliated to the Petroperú Network, have a maximum of 50 ppm of sulfur.

How are PETROPERÚ Gasoholes composed?

Our Gasoholes are composed of 92.2% vol. of gasoline of fossil origin and 7.8% vol. of fuel alcohol and do not contain tetraethyl lead.

What are the characteristics of the additives contained in PETROPERU Gasoholes?

Our Gasoholes contain high doses of state-of-the-art multifunctional performance additives, which meet the strictest requirements of the world's leading motor manufacturers. These additives have detergent properties that control the formation of deposits in the internal parts of the motor, guaranteeing a optimal operation of injectors for efficient fuel atomization, which allows better use of combustion energy, which is reflected in a better economy for the consumer.

Does the vehicle work better if I supply it with a higher octane Gasoline/Gasohol? Example: Gasohol 97 instead of a Gasohol 90

No, the gasoline engine is designed for octane according to the compression ratio of the vehicle. The operation of the engine will be optimal according to the octane required in the vehicle manual, which can be expressed in RON (currently used nationally) and AKI (used in the United States of America). In both cases, a Gasoline/Gasohol of equal or higher octane must be used within the different grades that Petroperú offers to the market.

Should Diesel and Gasoline/Gasohol be mixed?

No, the diesel engine, should only use Diesel and the gasoline engine should only use Gasoline/Gasohol. Both engines have completely different designs and use a fuel for which it was not designed will bring serious consequences in it.

How can I quickly determine that the fuel is in optimum quality conditions?

Performing a visual inspection, it should have a clear and bright appearance. If the fuel is opaque or turbid, it probably contains minimal amounts of water, which do not yet reach enough to achieve fuel separation (two phases).

What happens to Gasohol when water enters the fuel in the storage tank of the Service Station?

The alcohol that Gasohol has migrates towards the aqueous phase (water) causing the Gasohol to not have the optimum content according to national regulations (7.8% vol). This breach is fined by OSINERGMIN.

Does the vehicle run better if I fuel it with a higher-octane gasoline/gasohol? Example: Premium Gasohol instead of Regular Gasohol.

No. The Otto cycle gasoline engine is designed to work with the octane number according to the compression ratio of the vehicle. The operation of the engine will be optimal according to the octane number specified in the vehicle manual, which can be expressed in RON (Research Octane Number). An octane grade of gasoline/gasohol of the same or higher grade than that indicated in the vehicle manual must be used. For this, the following should be considered:

If the Vehicle Owner's Manual indicates:

- Less than or equal to 90 RON: Use Regular Gasoline or Regular Gasohol

- Greater than 90 RON: Use Premium Gasoline or Premium Gasohol

In accordance with Ministerial Resolution No. 469-2021-MINEM/DM that establishes technical quality specifications for Gasoline and Gasohol for automotive use, Premium and Regular

Do PETROPERU 95- and 97-octane Gasohols of have less than 50 ppm of Sulfur?
