Castrol Brands Toolbox

When it’s time for an oil change, which oil is right for an engine? The answer to that question gets more complex every day. The latest engines are getting smaller and more powerful all the time, and manufacturers are specifying complex full synthetic oils to cope with higher engine pressures and meet fuel efficiency targets.

Vehicle requires Advanced Full Synthetic oil with OEM & European Specs
Vehicle requires a Full Synthetic oil / Imports
Vehicle has 75K+ Miles
Vehicle recommends a Conventional oil

Brand Comparison

If your customer is driving a muscle car or a European import, the manufacturer may well specify a full synthetic motor oil. Alternatively if they’re driving an older domestic vehicle, the manufacturer may recommend a conventional oil. However, even though that’s the most economical option, a full synthetic will almost certainly look after your engine better. Knowing what engine oil to use at every oil change is essential.

  • 3x stronger than Mobil 1 against viscosity breakdown*
  • Advanced full synthetic
  • European specs (ACEA)

Superior sludge protection to help extend engine life

*As tested in the Sequence VH sludge test vs. API SP limits

  • Specially designed for engines over 75,000 miles
  • Protects against sludge, wear and burn off
  • Reduces phosphorous to protect your emission system
  • GTX High Mileage is a trade up option for conventional consumers with more than 75K miles on their engine and want the added benefit of emission system protection
  • EDGE High Mileage is a trade up option for consumers who want the performance and protection of EDGE, want the added benefit of emission system protection and/or have the requirement for a GM dexos® specification

All engine oils contain phosphorus – which is known to be a poison to the catalytic converter


Castrol GTX High Mileage and EDGE High Mileage offer Phosphorus Replacement Technology, a proprietary formula with reduced phosphorus content


Reduced phosphorus without compromising wear protection
