​Análisis técnico: Por qué el aceite Mobil AV1 fracasó y qué nos enseña sobre los PAO

Are PAO (Polyalphaolefin)-based oils really the ultimate solution for your engine? In this video, we conduct an in-depth analysis from a lubrication engineering perspective to demystify why this synthetic base, while popular, presents serious technical problems when not formulated correctly. Through the study of the aniline point and spectroscopy, we examine the well-known case of Mobil AV1 oil, revealing why its formulation failed in aviation engines by not keeping contaminants in suspension. If you want to understand the science behind lubricant selection and the real limitations of synthetic technology, join us for this technical review where we explain the critical importance of additive solubility and actual anti-wear performance. Here's a detailed summary of the video analyzing the drawbacks of PAO-based oils: • 00:00:00 Introduction to the PAO Oil Myth The video begins by debunking the widespread idea that oils based solely on PAO (Polyalphaolefin) bases are the perfect solution, pointing out that manufacturers often conceal their technical disadvantages, such as low additive solubility, lubricity, and anti-wear performance—areas where HC-based oils typically outperform PAOs. • 00:02:09 The Aniline Point Test The video explains the technical importance of solubility in engine oils, measured through the aniline point test. The lower this value, the better the oil's solubility. It highlights that, unlike mineral oils (with values ​​between 90 and 100), PAO oils can present problems if this value is too high. • 00:02:09 The Aniline Point Test The video explains the technical importance of solubility in engine oils, measured through the aniline point test.

This oil was withdrawn from the market after years of sale due to sludge formation and severe engine failures. This case serves as an example of the limitations of formulations based exclusively on PAO in keeping contaminants in suspension. • 00:06:24 Laboratory Analysis and Spectroscopy The data from an analysis of virgin Mobil AV1 oil is broken down. Despite attempts to formulate it with pure PAO, spectroscopy reveals that the manufacturer had to resort to adding esters to try to improve its properties, evidenced by high oxidation peaks, confirming that PAO alone was insufficient. • 00:06:24 Laboratory Analysis and Spectroscopy The data from an analysis of virgin Mobil AV1 oil are broken down.

This is compared with formulations from other manufacturers of the time, such as Amsoil or mineral oils, which presented more optimal values ​​(around 120), allowing for better solubility and less residue formation. • 00:25:29 Conclusion on Oil Formulation The video concludes that the superiority of a PAO base is not absolute and that its exclusive use can be counterproductive. The key to a good motor oil lies in the balance of its complete formulation, considering factors such as the aniline point and the proper interaction between base oils and additives.
