In the complex world of vehicle lubrication, it pays to understand the way ahead. Gone are the days when garages could rely on a single barrel of 10w40 oil to service every car that required oil. Driven by emissions regulations and a need for sustainability, carmakers are developing more complex engines. These often require specific additives, working conditions and thinner viscosities. Lubricants are expected to work harder, often in smaller quantities, so different vehicle marques have their own specifications – no more ‘one-for-all’ solution. Now more than ever, recommending or using the wrong oil could lead to catastrophic consequences for the engine.
