What are the most common engine problems in Toyota Camry models in Pakistan, and how can owners prevent issues like excessive oil consumption and carb

Common Engine Problems:

Excessive Oil Consumption: Older Toyota Camry models, particularly those with high mileage, can suffer from excessive oil consumption. This is often due to worn-out piston rings o r valve seals.
Carbon Buildup: Carbon deposits can form in the engine, especially in areas like the intake valves. This happens when the fuel quality is poor and combustion efficiency is reduced.

Impact of Fuel Quality in Pakistan:

Low-Quality Fuel: Pakistans fuel often contains impurities like sulfur, which can cause carbon buildup in the engine. Moreover, low-octane fuel can lead to incomplete combustion, worsening carbon buildup over time. This reduces engine efficiency and accelerates oil consumption.
Extreme Temperatures: High temperatures in summer and low temperatures in winter can affect the viscosity of the oil, leading to increased wear and tear. The engine’s cooling system may also struggle to maintain optimal temperatures under extreme conditions.

Prevention and Maintenance:

Use High-Quality Fuel: Whenever possible, fill up with higher-quality fuel from reliable stations, as it helps prevent carbon buildup.
Regular Engine Cleaning: Carbon cleaning services like walnut blasting can be used to remove carbon deposits from intake valves.
Frequent Oil Changes: Change the engine oil regularly every 5,000 to 7,500 km and use the recommended oil grade for your specific model.
Use Engine Additives: Some oil additives can help reduce oil consumption by improving the seal between the piston and cylinder walls.
Engine Cooling System Maintenance: Ensure the cooling system is properly maintained, including regular flushing of coolant and checking for leaks o r blockages.
