• Castrol-GTX

    Superior Deposit Protection*

    Castrol® GTX®

    is re-engineered with TriShield™ technology to actively protect against deposit build-up. TriShield attracts, captures and disperses small deposit particles before they become big problems. Engine deposits can turn into a thick, dark substance that can wreak havoc within an engine, building up and clogging oil passages. Deposit build-up can lead to reduced gas mileage, decreased engine performance, and in some cases, engine seizure. What’s worse, once it builds up in an engine, it’s almost impossible to remove.

    Industry Specifications and OEM Approvals by Grade:

  • Castrol Magnatec Logo

    Did you know testing confirms that up to 75% of engine wear occurs during the first 20 minutes of warm up?*

    When your engine stops, oil drains off critical engine parts, but Castrol GTX MAGNATEC’s intelligent molecules don’t –

    they form an extra layer of protection during warm up, when your engine needs it most, dramatically reducing engine

    wear and keeping critical parts up to 4X smoother.*

    * As tested in the industry Sequence IVA wear test.

    Castrol GTX MAGNATEC also delivers:

    Superior wear protection on critical engine parts

    Unsurpassed level of protection against viscosity breakdown

    Unique synthetic technology to fight against harmful sludge build-up

    High level of fuel economy based on US industry standards

  • Castrol-GTX-High-Mileage-Logo

    Castrol GTX High Mileage is the premium part synthetic motor oil specially formulated for vehicles with over 75,000

    miles. As vehicles age, they change and some of these changes can result in costly repairs or replacement. Catalytic

    converter failure is one of the most common – and costliest problems faced by higher mileage vehicles.

    All motor oil contains phosphorus to prevent engine wear. Phosphorus is an industry recognized catalyst poison.

    Castrol GTX High Mileage is specially formulated with less phosphorus than other leading oils, replacing it with

    advanced technology invented and patented by Castrol that helps prevent catalytic converter and emission system failure

    and delivers unsurpassed protection against sludge, wear and oil burn-off*

    *vs leading conventional oils, 5W-30 tested
