What is the best oil for a Corolla 1.6?
2 Answers
Toyota Corolla 1.6 is recommended to use Toyota Genuine 0W-20 full synthetic oil. The official recommendations for Toyota Corolla include 0W-20, 5W-20, 5W-30, and 10W-30 grade oils. Besides the original manufacturer's oil, you can also choose brands like Shell, Mobil, and Castrol. Below are the hazards of overfilling engine oil: 1. Increased fuel consumption: When the engine cylinder is overfilled with oil, it creates unnecessary resistance to the crankshaft's rotation, affecting power output and leading to higher fuel consumption. 2. Reduced power: Excessive oil entering the combustion chamber increases carbon deposits, raising piston movement resistance and decreasing engine power. 3. Environmental non-compliance: It worsens exhaust emissions, severely impacting the lifespan of the catalytic converter, and may even directly damage it.
I've been driving a Corolla 1.6 for several years and found that switching to full synthetic 5W-30 oil is the most worry-free choice. The engine runs exceptionally smooth with reduced noise and lower fuel consumption, saving about 1 liter per 100km in city driving. The owner's manual recommends synthetic oil viscosity, and 5W-30 suits most regions in China - quick cold starts in winter and no thinning in summer. I change oil every 8,000km to prevent oil degradation from damaging the engine. Occasionally check the dipstick - as long as the color isn't blackened. Never cheap out on inferior oil, reputable brands like Shell or Mobil are sufficient. Spending a little extra to prolong your car's lifespan is always wiser than engine repairs.
