Castrol Malaysia shows the difference between fake and genuine engine oil – don’t be swayed by “savings”

Castrol Malaysia has posted a video on its official Instagram page that shows the difference between genuine and fake engine oil. A long-present issue in Malaysia, fake engine oils should be avoided because it can lead to costly engine damage, offsetting whatever “savings” you gained earlier.

In the video, a fake bottle of Castrol Magnatec priced at just RM60 is unboxed and placed alongside an original, with both looking nigh identical at first glance. In fact, the company points out that aside from the cheaper-feeling label and cap, both bottles are very similar in appearance.

Pouring out the contents, the fake engine oil is observed to have a more golden colour and diluted, while also having a strong “burnt” smell. The genuine engine oil is the opposite, as it has a darker colour, is less diluted and doesn’t have said odour.

Taking care of your car’s engine requires a bit of research, so put in the work to survey the recommended retail prices of genuine engine oil by referring to official stores or online marketplaces. If you find a place selling the same engine oil for multiple times cheaper, be wary to ensure you’re not buying fake engine oil that can reduce the longevity of your car’s engine.

One initiative by the government to curb the sale of fake engine oils is a new regulation mandating engine oil products sold in Malaysia to be SIRIM-certified. Enforcement of the regulation was supposed to start in April this year but has since been postponed to October 2025.

Under the new regulation, all engine oils have to undergo an authentication process through SIRIM QAS International, which is responsible for certifying and issuing product compliance labels for that purpose. According to the Guidelines for Certification and Marking of Engine Oils for Motor Vehicles on the SIRIM QAS website, products have to undergo several tests before they can be certified.

Upon meeting compliance to these, the applicant will be given certification of a genuine product licence or a batch verification report, which it can then use as a basis to mark the product with the SIRIM genuine product certification. A conformity label, which must be affixed at the top of the container lid of the engine oil, will provide additional security. Periodic testing will be conducted to ensure compliance, with offenders receiving fines or jail time upon conviction.
