Oil Buying Guide For BMW 328i

Before choosing any oil for the BMW 328i, you need to know about the crucial details mentioned below.

1. Analyzing the Viscosity

The viscosity of the engine dictates how thin or thick the oil will be according to the temperature. Thinner oils have better oil flow and the thicker oils keep the engine parts well lubricated for a longer period. The BMW 328i recommends and performs the best under the 5W-30 oil. However, the 5W-40 viscosity can also keep the engine healthy. The 0W-30 and the 0W-40 will also be suitable in lower temperature conditions but provide thinner lubrication for the engine parts.

2. Choosing the best oil 

There are 3 major types of oils available in the market. The conventional oil, synthetic blend oil, and the full synthetic oil. The BMW 328i is a premium quality engine, therefore can work with either a conventional oil type or a full synthetic or synthetically blended oil. The recommended oil type is the Full Synthetic type as it is able to keep the engine functioning well over long periods and the intervals between oil changes are longer. However, the full synthetic oils cost more.

3. Engine Performance

The engine performance of the vehicle is the most important factor one needs to know. It all depends on the usage one does of it and thus to understand how much pressure the engine will go through. If you are a person who uses the vehicle on a daily basis with long-distance and improper roads, you should go for the heavily lubricated thick engine oil. Similarly, if you live in extreme cold weather and face the problem of poor pickup, then a thinner oil may be the way to go. It is important to realize that every vehicle undergoes different treatments and one needs to make an informed decision accordingly.

4. Additional Features

The additional features can be of crucial importance if one is confused between certain products. It helps in understanding exactly what you need your engine oil to do and makes it easier to identify what specific problems you need to be tackled in the engine.
