Castrol’s GTX helps extend engine life

For drivers it means having a car that they can rely on long into the future. For workshops it means building up a loyal base of customers who rely on your expertise and trust you to provide the ultimate care for their car.

Castrol GTX – keep engines cleaner for longer
The Seq VH test is acknowledged worldwide as the standard for engine oil performance in cleaning sludge. It’s a requirement of leading industry standards API, ACEA and ILSAC as well as many major OEM specifications. Castrol GTX doesn’t just meet these standards. It exceeds them.

Furthermore, today’s modern engines demand a lubricant that has been approved by the engine manufacturer and not just while under the warranty period. Using an engine oil that carries full manufacturers’ approval gives the workshop and their customers peace of mind rather than using a product that is not approved and just “meets” the specification or is “suitable for use”.

During more than 50 years of research and development, Castrol has developed a range of GTX variants aimed at specific vehicles. Castrol’s GTX range for Independent car workshops carries all the major manufacturers’ approvals, ensuring the vehicle being serviced receives the correct product that has the correct OEM approvals.

Specifications and Industry Standards of a selection of products in Castrol’s GTX range are listed below:

  • Castrol GTX 5W-30 C3 is approved for all vehicles where the manufacturer recommends an ACEA C3 product and has Volkswagen VW 504 00:507 00 approval along with the BMW LongLife-04 and Mercedes 229.31/229.51 and Porsche C30 and Renault RN0700 / RN0710.
