Castrol guarantee registration

With expertise in engine lubrication for over 125 years, we are confident in the quality of Castrol engine oils. No compromises.

 

If you have had your car serviced at a Castrol Service workshop in the United Kingdom or the Republic of Ireland in the last seven days, you may be eligible for a Castrol Guarantee.

 

The guarantee is available to Castrol Service customers who have had their car oil changed with Castrol EDGE, MAGNATEC or GTX products. Please refer to the terms and conditions for full eligibility details.

This guarantee takes effect 30 days or 750 miles (or 1.000 kilometers for workshops in the Republic of Ireland) from the engine oil change date, which ever comes first, provided a valid registration is in place.
