I am a fan of testing, so it was riveting to watch Australian made Penrite oil compete against the highest quality oil in the industry. In a series of videos the youtube channel Project Farm pitted a range of top oils against one and another, and remarkably Penrite made it to the final four, well done 👍. The video below is the quarterfinal where it is matched up against arguably the best oils in the market. Regardless of the result, one has to bear in mind boutique oils like Amsoil and Pennzoil are actually not available here through the usual auto chain stores, so they are typically priced much higher than Penrite oils. As those stores offer great discounts regularly, it makes Penrite oil seem like unbeatable value for money.
A caveat is that the correlation between the tests carried out in the video and real world effects in cars is still debated, so please watch it with a grain of salt. The charts shown in the video from lab measurement are certainly relevant.
