Should the naturally aspirated Bora use 5w30 or 5w40?

The original factory engine oil specification for the Volkswagen Bora is SM or higher grade 5W-40 oil. The reasons are as follows: 1. Engine protection: The Bora's engine operates with high efficiency and has a high compression ratio, resulting in relatively high internal engine temperatures. Using higher viscosity oil helps protect various engine components and cools them to reduce temperature. 2. Extending engine lifespan: Engine oil is a crucial factor affecting engine performance and longevity. When the car leaves the factory, the engine is filled with high-quality multi-grade viscosity oil, which can be used year-round except in extremely cold seasons and regions.
Our family has owned several cars, including a naturally aspirated Bora. I believe choosing engine oil mainly depends on the temperature and personal driving habits. Generally speaking, 5W30 has better fluidity and can be used year-round in most regions, especially suitable for colder winters as it's less prone to freezing. I've tried 5W40, which performs more stably during summer heat, with slightly reduced engine noise, but it may increase fuel consumption slightly. I suggest checking your car's maintenance manual first—Volkswagen often recommends 5W30 as the standard option. If you don't frequently drive long distances or on highways, this grade should suffice. Oil changes don't cost much; the key is regular maintenance—don't risk engine damage to save a few bucks. If you live in a perpetually hot climate, then considering 5W40 would make sense. Ultimately, safety and peace of mind come first.
I'm a practical person. As someone who regularly drives a Bora, 5W30 is sufficient and offers good value for money. I live in a southern city and have been using 5W30 for years. The engine has always run smoothly without any issues. The difference in oil viscosity lies in environmental adaptation: 5W30 heats up quickly in winter and performs well in summer too; 5W40 is suitable for more extreme heat or aggressive driving, but naturally aspirated engines aren't that delicate, so there's no need to fuss over expensive options. You should regularly check the oil level and quality, changing it every six months, which is far more important than choosing which type. Remember, for the first few years of a new car, just follow the manual to avoid warranty issues. Spend time understanding your driving habits—saving fuel and money is what really matters.
