Last but not least, there’s the Motul 8100 X-max 0W-40. Here’s a quick rundown of 8100 oils and what they’re optimized for. The Motul 8100 series of engine oils use a combination of PAO and ester based oils, depending on their intended application. When you start the engine first thing in the morning, this protective film keeps friction at bay until you get positive oil pressure. On the other hand, ester-based oils are incredibly resistant to high heat, which is why they’re the base stock of choice for high-performance and motorsports applications.Īn ester-based oil is also naturally attracted to metals resulting in a long-lasting protective film that blankets all of your engine internals. This makes them perfect for environments where it gets freezing cold, and your engine needs consistent cold start protection. PAO or Poly-Alpha-Olefins are immensely more stable than mineral oils when exposed to aggressive temperature differentials. Oils from these two groups are better suited to handle extreme operating conditions, which are a normal occurrence in high-performance engines, but also regular modern engines. Group 4 PAO and Group 5 ester-based oils are built to withstand high temperatures for long periods of time without losing stability. Mineral oils simply weren’t up to the task of handling these new requirements, hence why a new solution was necessary. The ability to machine engine components with tight tolerances meant that higher internal temperatures are much more common. Within the last several decades, engines have become more efficient both in terms of power output and fuel economy. However, modern engines are a whole different beast. Older engines benefit from Group 1 and Group 2 lubricants solely based on how these oils behave. Mineral oils of old were an efficient solution for the challenges car manufacturers faced at the time. Low Friction and Wear Protectionīefore we get to specific 8100 variants, let’s briefly discuss the advantages of Group 4 and Group 5 synthetic oils. ![]() That way you can find a lubricant that meets the requirements set by your car’s manufacturer, but also the current state of your engine. ![]() Furthermore, every version of Motul 8100 comes in a range of viscosity grades. The idea behind the 8100 series, aside from offering a universal answer to niche car manufacturer requirements, is to give drivers plenty of flexibility.Īs a result, there are oils in the 8100 family designed for economy, some that are formulated to offer maximum protection, handle powerful engines, and more. Using a high-quality base stock formula sets the foundation for everything else. Some 8100 series oils are ester-based, like the high-performance Motul 300V series, while others feature a PAO (Poly-Alpha-Olefins) base stock with its various synthetic formulations. All of the 8100 oils use a quality base stock that meets and generally exceeds OE specs. These oils are 100% fully synthetic Group 4 and Group 5 lubricants that cater to different performance profiles depending on what you drive, and how you drive it. Yet, the 8100 family of engine oils does exactly that. Satisfying the world’s leading car manufacturers and their lubrication requirements is a tall order.
