We've made it easier than ever to protect your engine. It's as simple as 1, 2, 3.
ENROLL ONLINE.It's fast and easy.
MAINTAIN YOUR VEHICLE REGULARLY.Frequently-changed oil makes for a happy engine, so get your oil changed every 4,000, 5,000 or 6,000 miles – depending on which Castrol product you use.
KEEP YOUR RECEIPTS.While we've made it easy for you to record your vehicle service online, all you need to do is keep your receipts if you ever need to make a claim.
  1. What is the Castrol Engine Warranty? The Castrol Engine Warranty is a program that rewards our loyal customers by guaranteeing their engine's life with the use of Castrol's premium line of motor oils.
  2. Am I eligible? Yes, your vehicle is eligible if it is a:
    • gasoline passenger car, van or light truck
    • weighs less than 10,000 pounds
    • less than 6 years old and has less than 100,000 miles
    • has the original manufacturers' engine
    • has valid state inspection sticker at the time of enrollment (if applicable to your vehicle).
  3. How do I enroll? It's easy. Once you've reviewed the Full Program Details, you can register online.
  4. How many vehicles can I register? As many as you have, as long as they meet the program requirements.
  5. How do I keep my warranty valid? Be sure to maintain your vehicle regularly. Always follow your manufacturers' recommendation, including those around severe driving conditions. However for the Castrol Warranty the motor oil in your vehicle must be changed every 4,000, 5,000 or 6,000 miles – depending on which Castrol product you use.
    You should also keep your Castrol oil change service receipts or Castrol Motor oil purchase receipts. Receipts must indicate the installer name, date of service, odometer reading, brand of Castrol motor oil installed and price paid.
    Be sure to read the Full Program Details for more information.
  6. Well, I know when I am covered. When am I not covered? The only claims we don't cover are when the damage is the result of a collision, flood, fire or neglect.
    To keep things simple, the following items are covered:
    • Pistons & Rings
    • Turbo Bearings
    • Timing Chains
    • Cylinder Lining or Bore
    • Oil Pump
    • Rods & Rod Bearings
    • Balance Shafts & Push Rods
    • Cam Shaft & Bearings
    • Crankshaft & Bearings
    • Valve Lifters
    • Rocker Arms & Pivots
    • Distributor Drive Gear
    • Wrist Pins & Bushings
    • Timing Gear or Sprockets
    • Valve Stems & Guides (Grinding adjustments excluded)
    And that means, the following items aren't covered:
    Timing belt failure; improper oil selection, service or maintenance; defect attributable to the vehicle manufacturer; improper installation of any part; coolant contamination; or failure to keep the motor oil and engine coolant at levels prescribed by the manufacturer.
  7. What if I am missing a receipt? Nobody's perfect. You are allowed one exception over the life of your warranty. If you were up to 1,000 miles late for an oil change, you will be forgiven (just this once, don't push it).
  8. If I sell my vehicle, is my warranty transferable? No. The warranty is not transferable. But if you sell your vehicle, feel free to let your buyer know that if he or she meets the requirements, they can register for the warranty too.
