At Rofeibi, we stand behind the quality of every lubricant we produce. Our warranty ensures that your purchase is protected against material or manufacturing defects so you can use our products with confidence.

Warranty Coverage & Terms

All Rofeibi lubricants come with a limited warranty covering defects in materials and manufacturing.

• Warranty period: Clearly displayed on:
  • The product packaging (near the batch code)
  • The official product webpage
• If the warranty period differs between packaging and the website, the longer period
• Coverage starts on the date of purchase, verified with your sales receipt.

This Warranty Covers

• Base oil quality – molecular integrity and oxidation stability
• Additive systems – correct formulation without precipitation or separation
• Packaging – sealing, labeling, and container integrity

Exclusions

This warranty does not apply to:

• Products resold as secondhand
• Damage caused by:
  • Improper storage (extreme heat > 60°C or cold < -30°C)
  • Mixing with incompatible fluids
  • Use beyond recommended drain intervals

What Counts as a Defect

We cover defects that prevent the lubricant from meeting Rofeibi’s published quality standards.

When defects appear:

• On first inspection (e.g., leaking bottle)
• Within the first few operational cycles
• By around 50% of the recommended drain interval at the latest

What Is Not Covered

Some situations fall outside warranty coverage:

• Natural wear
  • Normal viscosity breakdown with extended use
  • Routine deposit accumulation in engines
• Misuse
  • Using motorcycle oil in a diesel engine
  • Extending service intervals more than 2x beyond Rofeibi’s recommendations
  • Contamination by fuel, coolant, or external substances
