A fuel with a higher octane content can always be used without hesitation with any petrol. We recommend the uses of SOCAR VELVET 98 for all gasoline engines.

SOCAR VELVET 98 can be mixed with other types of petrol without hesitation. This is because all types of petrol sold in Switzerland comply with the fuel standard (SN EN 228).

We recommend, though, that you use SOCAR VELVET 98 regularly so that you can enjoy the full benefit of the double protection formula and permanently protect your engine from deposits.

SOCAR VELVET 98 contains a highly effective, new double-action formula specially designed to keep clean the intake system and especially the intake valves.

• Powerful cleaning additives ensure that existing accumulations of dirt in engines caused by refuelling with additive-free fuels are largely removed. Valves and engine components receive the care they need to keep working like they always used to. Used regularly, SOCAR VELVET 98 thus lengthens component lifetimes.
• In addition, protective agents form a layer over the delicate parts of the engine like a second skin to prevent new deposits from forming.

Furthermore, SOCAR VELVET 98 demonstrates a high knock resistance with 98 octane. Modern engines featuring intelligent knock sensors can also unlock the potential of fuels with high octane ratings to enhance their performance and reduce their fuel consumption.

Fuels are produced in refineries in accordance with the quality regulations defined in the SN EN228 fuel standard (known as base fuels). These base fuels are available to all market participants. Every type of fuel marketed in Switzerland complies with these minimum statutory requirements.

The use of a standard quality fuel does, however, lead to the formation of deposits that contribute to polluting the most important parts in the engine (especially fuel injectors and intake valves).

For this reason, SOCAR enhances the respective base fuel for all types of fuels it markets by blending in special SOCAR cleaning additive packages, which is what yields the SOCAR-branded fuel. This happens when the tanker lorries are loaded.

Unlike fuels sold without cleaning additives, these do not leave any damaging deposits in your engine. The problems of deposits forming on fuel injectors and intake valves can be avoided by using a higher quality fuel (with additives). This helps to keep your engine clean so that it can deliver the kind of performance the manufacturer intended.

The name SOCAR VELVET 98 reflects SOCAR’s high standards in terms of quality, signifies innovation and exudes a strong sense of self-reliance in the field of mobility. VELVET is distinctly smooth to the touch. It is a multi-layered fabric known for its fine surface. This surface must, however, be protected and maintained, just like the surfaces of the various engine parts. This protection and maintenance is provided by SOCAR VELVET 98.

It is not compulsory to blend in additives in Switzerland, even though this is recommended by European, American and Japanese carmakers in the World Wide Fuel Charter. It is left up to the oil companies whether they blend these additives into their fuels. This depends on the corporate strategy regarding product quality and the marketplace.

HVO diesel is made from biogenic waste, such as used vegetable oils or food waste, and is then processed into diesel. For technical reasons, SOCAR does not add cleaning additives to SOCAR Diesel HVO 25.

SOCAR Diesel HVO 25 is a mixture of conventional diesel and approximately 25% renewable diesel, which is obtained from reprocessed vegetable oils and animal fats. For technical reasons, the exact proportion of HVO diesel may differ from the 25% figure by a few percentage points.

SOCAR Diesel HVO 25 is compatible with all vehicles approved for conventional diesel according to SN EN 590; therefore, any vehicle that can use conventional fossil diesel can also be filled with SOCAR Diesel HVO 25.

If your vehicle manufacturer has approved the use of conventional diesel according to SN EN 590, it is absolutely fine to mix SOCAR Diesel HVO 25 with the diesel already in your tank.

HVO diesel is based on renewable raw materials, and its combustion in the engine produces lower greenhouse gas emissions, lower soot and particulate emissions, and lower NOx and SOx emissions than fossil diesel. As a result, HVO diesel improves the fuel’s LCA (life cycle assessment).

HVO diesel is more expensive to produce than conventional diesel, as it includes raw materials that often cost more than fossil raw materials. Raw materials such as used cooking oils or animal fats are only available on a limited scale. Fuel made from 100% HVO diesel would therefore cost significantly more than conventional fuels. In addition, HVO 100% can only be used in vehicles for which it has been explicitly approved.

Yes, SOCAR Diesel HVO 25 is usually slightly more expensive than conventional SOCAR diesel. This is due to the higher production costs resulting from the use of renewable raw materials with limited availability.
