What will happen if fuel consumption increases after changing to Castrol engine oil?

[IslaRose]

It is normal for fuel consumption to increase after changing to Castrol engine oil. The new oil is more viscous in its initial state, but as it is used, the oil will become thinner, reducing the resistance to the internal components of the engine, which will naturally lower fuel consumption. Try to use the air conditioning less: Especially during traffic jams or when parked, avoid keeping the air conditioning on continuously. Turn off the air conditioning completely when not in use: When the air conditioning is not needed, turn it off completely. This not only reduces energy consumption but also minimizes wear and tear on the air conditioning system. Set the air conditioning to the highest level after starting the vehicle: After starting the vehicle, set the air conditioning to the highest level. Once you feel it has reached sufficient cooling, turn it off. This allows the air conditioning to skip the step of mixing with warm air, achieving maximum cooling efficiency while also saving fuel to some extent.
