Formula Shell Regular unLEADED
Description

Formula Shell Regular Unleaded is a motor gasoline formulated for cars and motorcycles of octane requirement lower than that of a premium-grade motor gasoline.

In addition, the volatility of Formula Shell Regular Unleaded is controlled to provide easy starting when the engine is cold and prevent vapour lock when the engine is hot.

Safety

Formula Shell Regular Unleaded is a mixture of C4 to C11 hydrocarbons. This gasoline is “highly flammable”, its flash point being well below ambient temperature.

In the event of FIRE, dry powder, BCF or carbon dioxide extinguishers may be used. Do not use water jets as this will only cause the product to spread on top of the water.

The principal hazard is from fire and explosion.

I can't use Shell (Regular and V-Power) on my V6. Starts to ping under load. Switched to Esso/Mobil.
