Castrol GTX High Mileage Engine Oil has been exclusively and professionally engineered for vehicles with more than 120,000 KM on the odometer. This is the leading consumer brand of high mileage motor oil.
GTX High Mileage Engine Oil is processed using Phosphorous Replacement Technology to replace some of the phosphorous with an advanced additive that maintains robust wear protection. This engine oil is a one-stop solution if you want to extend the life of your high mileage engine and emission system.
This multi-grade oil has three grades, i.e., 5W20, 5W30, and 10W30 (W stands for winter). The synthetic 5W-30 oil means that it can flow as easily as a 5 Weight oil in winter temperatures but is as thick and viscous as a 30 Weight oil once normal engine temperature has been reached. No grades are inferior or superior to the other. Choose the right oil for your vehicle based on two parameters, i.e., the temperature at which you regularly drive and your engine’s recommended oil viscosity grade.
