AVYOL Lubricants are blended with Premium Hydro cracked base stocks of Group II & III to deliver the requirements of modern passenger car engines of most of the OEMs. AVYOL Engine oils are blended with advanced additive packages to meet the latest specifications of API SN and ASIA A5/B5 for both petrol and diesel engines. AVYOL has also in its range synthetic engine oils made from poly alpha olefins (PAO) base oils which provide the ultimate performance in terms of cleaner engine and longer engine life.Read More
On the four-wheeler front, the improved efficiencies of automobiles demand more from oils that lubricate and cool the engines. The necessity to achieve greater fuel economy has driven new engine technologies.
Gasoline Direct Injection (GDI) involves the high-pressure injection of fuel directly into cylinder combustion chambers rather than through intake valves. Turbochargers used to be found exclusively in racing and high-performance sports cars, essentially they recycle hot exhaust gasses to increase power. Downsizing some engines are going down as small as one litre in efforts to reduce mass and weight to improve fuel efficiency.
In the course of trying to develop more fuel-efficient engines without compromising power, manufacturers encountered something called LSPI (low-speed pre-ignition) – this is unwanted and uncontrolled pre-ignition in the combustion that can severely damage an engine over time. LSPI is largely a result of combining the major engine advancements into one package. This combination of technologies stresses the engine to a higher degree and leads to a need for improved motor oil to provide greater protection.
The smaller, GDI and turbocharged engines run hotter, experience more stress and have a higher power density; meaning the oil has to work a lot harder to protect the parts. That is why we have been seeing major development in the types of oils that are required for newer engines. OEMs have been moving towards ever thinner viscosities because they produce less fluid friction or resistance and therefore deliver better fuel economy.
