Here's Why LIQUI MOLY Actually Works

Blog Feature

If I asked you to name a brand of motor oil, a number of brands might pop into your mind. Castrol, Mobil 1, Valvoline, etc. One thing in common among these brands is the ability to find them anywhere you go. The convenience is undeniable, and because you've used them for years, you have no reason to use anything else.

On the flip side, what if there was something a little bit better? A product that gave you just that little extra peace of mind? Sometimes it's worth looking a little harder for a better product. Enter: LIQUI MOLY.

LIQUI MOLY may be a relatively unknown brand in North America, but the German company has been around since 1957 and to this day, still manufactures all of their products there. Their first product, MoS2 oil additive, contained the solid lubricant molybdenum disulfide which allowed engines to run for a short period of time without oil, which was perfect for emergency situations.

Molybdenum Disulfide in its natural form is similar in feel to graphite – the same, slippery stuff found on the tip of your pencil. MoS2 (the chemical composition), when tested for friction, has a coefficient value of <0.1. For comparison, Teflon on Teflon has a coefficient of 0.04 while steel on steel has a coefficient of 0.57. Alternative uses of MoS2 include gun lubrication and CV joints. And when you're talking engine friction, lower is ALWAYS better.

So what makes LIQUI MOLY Motor oil different? Let’s start with some basics.

Your engine contains multiple moving components such as your crank, valves, and pistons. In addition to these movements, there are thousands of explosions every minute that occur in the combustion chambers. Heat and friction in an engine, when not properly managed, leads to engine wear. The only way to reduce this is to make sure you choose the right engine oil.

If you live somewhere that experiences snowy weather on a recurring basis, it's normal to start your car in extremely cold conditions. Zero degrees Fahrenheit is not that uncommon, and in these conditions, it's important that your engine oil is up to the task, because cold weather will reduce the viscosity of the oil, potentially causing dry running of your engine for a short period of time. In this case, the film your oil leaves behind is extremely important, as is it's ability to flow at low temperatures. Multiply this over a number of cold starts with the incorrect oil, you could end up with increased engine and oil pump wear.

When riding a motorcycle, the high RPMs of the engine demand slightly more attention than normal. The smaller components can lead to greater oil wear due to high-shear conditions, situations where the oil is forced from a high pressure to low pressure area (piston rings, oil pump, etc) or vice-versa.

If you’re the type to take your car out onto the track, you’ll obviously be stressing the engine and all it's rotating components more than the average driver. Increased heat will cause oil to break down faster, and again, the high RPMs demand consistent lubrication.

Lastly, maybe you’re the type who drives an older vehicle and are more conscious about engine wear, like me. With my engine nearing 460,000 kms, I find it important to always fill up with quality motor oil.

Keep in mind, today's modern engines are designed and manufactured to such high tolerances that choosing the wrong oil viscosity really can be harmful to an engine. As a visual, image a pump that was designed to move water from one place to another. Now, imagine that same pump trying to move honey...it's just not going to work and that pump will die very quickly. Modern engines that are spec’d with lower weight oils (0W20) may have situations of increased wear if a heavier weight oil is used (10W30).

So let’s get back to LIQUI MOLY.

Generally, racing is a great place to advertise your products, not only for the publicity but for the worse-than-real-world conditions race cars endure. Since 2015, LIQUI MOLY has been the sole provider of lubricants to all the Moto2 and Moto3 race teams. The fact that LIQUI MOLY supports these racing series shows that they are willing to stand behind a good product. Without proof of how good your products are, what’s the point?

Liqui Moly MoS2, still containing molybdenum disulfide like their first product, has been formulated as an almost be-all-end-all engine oil. It has good cold-start behavior, as well as improved wear characteristics for modern engines.

Liqui Moly MoS2 is also recommended for older Porsches with air-cooled engines. The extra additives are very effective at reducing wear for high-heat situations, another difficulty for oil manufacturers. High heat = lower viscosity of the oil, and in extreme cases, less lubrication. The MoS2 additive coats all moving components with a low-friction surface to mitigate any problems that may arise with the oil. When you’re dealing with 40-50-year-old cars and engines, why not use the best?
