Sparesbox Road Test: Liqui-Moly Engine Oil

Engine oils are often a hot topic between car enthusiasts and can quickly turn into heated arguments depending on who you side with. With the basis for opinions varying from “Joe’s Oil sponsors John.Q Motorsport so they must use it” to “their TV ad said it’s designed for cars like mine“, the onus is often placed on people like myself, Your Mechanic, to provide the insight and use an oil I trust to stand up against the demands of your car.

Be it the daily commute to work, or a day’s worth of backbreaking rally stages. After all, if your car lets you down after a service, be it the mechanics fault or the oil he used, you probably won’t be going back – am I right?

You might assume that for my own cars, by which many in the trade judge others, I would be very particular about my oil selection and you would be right. What better resume for a product than “I use it my pride and joy“. For my Alfetta GTV and Alfa 75, that choice has always been Liqui-Moly. This decision was easy after making the switch in a customers track car and immediately noticing reduced engine noise and consistent oil pressures at a higher temperature.

Both cars take vastly different oils. The GTV receives nothing but Liqui-Moly’s 20w50 MOS2 oil. The 75’s V6 – an engine renowned for being particular about oil use – uses Liqui-Moly’s 10w60 GT1 RaceTech to which I also add their MOS2 (Liquified Molybdenum Disulfide) additive – the brand’s first product and namesake.


What does MOS2 mean for my car?

MOS2’s significance as an additive cannot be understated. It can withstand unimaginably immense pressures and temperatures, and was initially designed to maintain lubrication in piston-driven aircraft engines in the event of a loss in oil pressure. MOS2 is a polar molecule, meaning it has a natural attraction to other metals. This coupled with its non-solubility in oil means that the MOS2 bonds to your engine’s internals and bearings to forms a sheer proof protective coating. MOS2 workS in a very similar way to Zinc, which has been used in engine oil for decades and is consistent in Liqui-Moly oils as well.

MOS2 can be used in any oil in any car, be it petrol, diesel or LPG; and at any point in the cars life. If you’re lucky enough to have a freshly rebuilt engine, consistent use of MOS2 additive at each oil change will ensure your engine’s lifespan and performance (do this after run-in, your engine builder will have a specified oil for run-in).


Does Liqui-Moly have an oil suited to my vehicle?

Liqui-Moly’s range is one of the most exhaustive in the industry with an oil to suit almost every application. Their 40+ years of success in the motor oil industry is no accident. With state of the art chemists and plants in Germany, they have even developed a DSG transmission oil for those vehicles in need, as well as oils specifically designed for late model German vehicles, high-mileage cars, race/performance cars, and classic cars. Liqui-Moly have a solution for most cars on the road that comes without compromise on quality so you can get behind the wheel with the confidence you’ve done the right thing by your engine and lubricated it with an oil that can go the distance; be it a commute to work, a Sunday morning drive on your favourite B-road, or a Finish line 12 hours away.
