With expertise in engine lubrication for over 120 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 last seven days, you may be eligible for a Castrol Engine Warranty.
The warranty is available to Castrol SERVICE customers who have had their car oil changed with selected Castrol EDGE, MAGNATEC or GTX products. Please refer to the terms and conditions for full eligibility details.
18,000 miles or 12 months after oil change, whichever comes first
This warranty takes effect 30 days or 1,000 miles from the engine oil change date, whichever is later, provided a valid registration is in place. A claim is only valid if all criteria are met, which are outlined in the terms and conditions.
The Castrol Engine Warranty covers the following items:
Up to £3,000 in respect of any claim.
Vehicles with an odometer reading of over 100,000 miles at the date of the oil change only have coverage of 50% of the actual claim, subject to a £1,500 limit.
Have your oil changed using eligible Castrol EDGE, Castrol MAGNATEC or Castrol GTX products at a Castrol SERVICE workshop and complete your registration on this website within seven days. Please keep hold of your invoice as proof of service showing when the oil was changed. It’s quick and easy!
