Motor oil sold in large drums is not inferior in quality to that in smaller tubes, since both variants are produced on the same lines and undergo similar control. The real danger comes from unscrupulous service stations that cannot guarantee the authenticity and proper storage of the product.
Risks of bulk oil
Without a traceability system, such as is expected to be introduced in our country, it is almost impossible to determine the origin of the oil. Uncertified service stations can dilute the oil, add used oil, or store the drums incorrectly, which leads to the breakdown of additives and a change in quality.
Potential damage to the car
Failure to comply with the correct viscosity specifications can lead to serious problems. Insufficient viscosity can cause a shortage of oil in the engine, and an excess of some elements such as zinc or molybdenum can damage catalytic converters. If you are wondering whether to choose bulk oil, always trust only proven service stations and suppliers.
