What type of engine oil is suitable for a 1.5T engine?
2 Answers
Fully synthetic engine oil is suitable, generally requiring replacement every 8,000-10,000 kilometers or every six months to a year. If the vehicle is used infrequently, the oil may oxidize and degrade over time, necessitating replacement within a year. Semi-synthetic engine oil should be replaced every 6,000-8,000 kilometers or approximately every seven months. Mineral oil requires replacement every 5,000 kilometers or every six months. Precautions for changing engine oil: 1. Do not overfill: When changing the oil, always pay attention to the oil level mark. If there is too much oil, the excess can easily overflow into the combustion chamber, leading to carbon buildup over time and, in severe cases, may cause oil burning. 2. Do not underfill: If the oil level is below the minimum mark, it can result in low oil pressure, reducing the lubrication effectiveness. In such cases, simply top up with the same type of oil.
I drive a 1.5T SUV, mostly for commuting, and I recommend using synthetic oil because it withstands high temperatures and is less likely to burn out. Turbocharged engines generate a lot of heat under boost, and synthetic oil offers better wear resistance—don’t skimp on this. I usually use 5W-30 viscosity, as clearly stated in the manufacturer’s manual. Always check your car’s manual. Conventional mineral oil saves money but performs poorly; you’ll feel the strain even on highways, and it’s worse in hot weather with heavy traffic. Change it every 5,000 km and have the mechanic check oil levels and impurities during maintenance—this extends engine life and saves fuel costs. Don’t underestimate oil choice; engine repairs are shockingly expensive.
