Fuel quality

INA continuously takes care of the quality of the fuel it offers customers. Before being placed on the market, all INA fuels undergo verification, a regular quality control procedure in compliance with European standards. Furthermore, INA’s fuels from retail sites must meet the requirements defined by the Regulation on the quality of liquid petroleum fuels for the purpose of ensuring human health and environmental protection. Supervision over the fulfillment of the requirements of the regulation is carried out by an independent inspection body.

Additional internal fuel quality controls are carried out throughout the supply chain, from refineries to logistics warehouses and transport to retail sites, which ensures high fuel quality at more than 300 retail sites.

To respond to the increasingly strict requirements of European directives, the automotive industry and environmental protection, INA Class Plus fuels with Expert additives were developed. The efficiency of new, improved formulations of additive fuels was tested in Research and Development, in the Central Test Laboratory and in the independent Austrian motor testing center Drive Technology Centre.

INA Class Plus – Just refuel and drive

Road traffic safety

INA takes care of the overall life and durability of your car’s engine with its new Class Plus fuels. Your duty is to stay safe while driving and we have a few useful advices to share and make sure you reach your destination safely and stress-free.

Periodic inspection

Have your vehicle inspected regularly: change your engine oil, check the pressure in your tires, make sure your brakes, lights, and direction indicators all work properly.

Proper positioning behind the wheel

A good seating habit behind the wheel can protect you in case of an accident. But do you know how to sit in the car properly? Press your shoulders firmly against the seat, keep your legs bent in the knees, and have your hands on the wheel in the “quarter to three” position.

Fasten your seatbelt!

This one simple habit can save lives. It has been proven that the use of seatbelts reduces mortality in traffic accidents by as much as 50%!

Don’t drive when tired

Take regular breaks from driving, get out of the car and stretch out your legs. In case of driver fatigue or drowsiness, take a rest.

Keep a safe following distance

Tailgating is the most frequent cause of car accidents. Keep a sufficient following distance to reduce the possibility of collision.

Respect the speed limit

Exceeding the speed limit puts you and all other traffic participants in danger. Also, your wallet may not like it.

As of 1 January 2025, all INA fuels are Class Plus fuels with Expert additives. Class Plus Premium fuels with enhanced additives have also been introduced, offering top tier performance.
