YAKARTA, KOMPAS.com – Cars that have not been used for a long time can cause changes in the fluid in them. There is no exception to fuel or gasoline in the tank.
In the automotive world, there is the term obsolete gasoline. This term is applied to gasoline that is deposited in the fuel tank for a long time until it finally affects its performance.

Didi Ahadi, Technical Support Manager at PT Toyota Astra Motor (TAM), said that when the fuel cap is opened, the odor produced is generally different from that of normal gasoline.
“The octane in gasoline decreases due to evaporation in the tank and the vapor mixes with the gasoline in the tank,” Didi said, when he was contacted by Kompas.com recently.
Didi added, car engines can still be started. However, combustion is not perfect. Therefore, the performance of the car will also be affected.

Tri Yuswidjajanto Zaenuri, an energy conversion expert at the Bandung Institute of Technology and Aerospace Faculty, said that olefin exists in gasoline. With the help of oxygen and heat, the olefins will form gum.
“If chewing gum appears in the fuel, the gas pump can suck up this gum and take it to the combustion chamber. The gum is sticky, so it can become clogged at the service station,” Yus said.
Yus said the service station’s rotation would be reduced because it was hampered by the gum. When the engine needs more gasoline intake, but the gas pump cannot channel it properly because it is clogged, the engine ends up faltering or “brebet”.
