Caltex Guards Fuel Tanks

Caltex Philippines has advised motorists to inspect their vehicles’ fuel caps and filler areas as persistent rain raises the risk of water entering the fuel tank.

Water contamination may gradually affect engine performance and lead to more expensive repairs if it is not detected early.

Drivers should check the fuel cap for cracks or other signs of wear. It should also be securely closed after every refueling stop.

Dirt, leaves and other debris should be cleared from the fuel filler area. A clean surface allows rainwater to drain instead of collecting near the cap.

Caltex also recommends parking under cover during heavy rain or flooding. Motorists may consider delaying refueling after a strong downpour, particularly in flood-prone areas, as water could enter a station’s storage or dispensing equipment.

Keeping the fuel tank reasonably full can also help. Less empty space inside the tank may reduce the formation of condensation.

Drivers who regularly pass through flood-prone locations should consult their vehicle manufacturer or a trusted mechanic about precautions suited to their particular model.

Possible signs of water contamination include shaking at low speeds and difficulty starting the engine. A vehicle may also stall soon after starting or feel sluggish on flat roads.

Rougher exhaust and unusual engine sounds after driving through heavy rain or flooded sections may also point to a fuel-system problem.

Motorists who encounter several of these symptoms should have the fuel system inspected before continuing to use the vehicle. Early detection may help prevent further engine damage.

Caltex Philippines General Manager and Country Chairman Pongtorn “Bon” Tangmanuswong said wet-season driving can place added strain on a vehicle’s fuel system, although many motorists may not consider the risk until symptoms appear.

He said Caltex applies quality controls intended to keep its fuel free from water. The company’s fuels also contain Techron, a cleaning additive designed to remove existing engine deposits and prevent new deposits from forming.

Motorists may visit a Caltex station with autoPro for a fuel cap and filler inspection as part of their rainy-season maintenance routine.
