Castrol GTX High Mileage motor oil is the leading consumer high-mileage brand. It’s a synthetic blend motor oil that helps extend the life of your engine by protecting against sludge, wear and burn-off. Castrol GTX High Mileage is also engineered to protect your emission system. One of the leading causes of ‘check engine’ lights coming on in high mileage cars is catalytic converter failure, which can be caused by phosphorous in engine oil. While phosphorous is present in all engine oils for its ability to reduce wear, it is effectively poisonous to catalytic converters. Castrol GTX High Mileage is formulated with Phosphorous Replacement Technology to replace some of the phosphorous with an advanced additive that maintains robust wear protection. When you want to extend the life of your high mileage engine and emission system, there is no better choice than Castrol GTX High Mileage.

Product Features:
  • Phosphorus replacement technology to help extend the life of the emission system
  • Superior dispersancy that fights sludge build up
  • Exceptional oil burn-off protection exceeding industry standards (based on api and acea volatility specifications)
  • Seal conditioners to help reduce leaks
  • Advanced additives that minimize engine wear
  • Improved fuel economy (in 5w-20, 5w-30 and 10w-30 grades versus industry specifications)
  • Meets or exceeds api sp/sn plus/sn, ilsac gf-6 and latest ford specs
