Nowhere are the advances in automotive fluids more evident than in motor oil. Many new weights and formulations have been created to meet the demands of today’s modern engine designs. Modern engines have more parts and much higher tolerances. Every year, vehicle engines make more power and get better fuel economy. And with all the complication and sophistication, they still have to be durable for 5,000 miles or more.
That's where the new grades of engine oil come in, Oils have to be formulated to lubricate, protect and clean all of those engine parts, big and small. The oil has to be thin enough to get into the small passages, yet resistant enough to vaporization. In Most modern engines the oil also acts as hydraulic fluid, changing the camshaft timing and disabling cylinders for better fuel economy. Make sure your using the correct oil your vehicle manufacturer requires.
