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 a synthetic blend engine oil that prolongs the engine life by protecting it against sludge, wear, and burn-off. This oil is also liquid engineered to protect the vehicle's emission system. Phosphorous in engine oil is a leading cause of catalytic converter failure in high-mileage cars. Although phosphorous is available in all engine oils because of its potential to reduce wear, it is poisonous to catalytic converters.
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 10W-30 oil means that it can flow as easily as a 10 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.
