Why Does My BluePrint Engine Need Zinc (ZDDP) In The Oil?

Many customers ask whether BluePrint Engines require zinc additives and what role ZDDP plays in engine protection. ZDDP, or Zinc Dialkyldithiophosphate, is an anti-wear additive commonly used in engine oils to help protect critical engine components from wear during operation.

 What Does ZDDP Do?

ZDDP helps create a protective film between metal components under high loads.

This protection is especially important for:

  • Camshafts
  • Lifters
  • Valve train components
  • Pushrods
  • Rocker arms

ZDDP has been used in performance engine oils for decades to help reduce metal-to-metal contact.

Do BluePrint Engines Require Zinc Additives?

BluePrint recommends using high-quality oil that meets the requirements specified for your engine.

For break-in and many performance applications, oils containing adequate levels of zinc and phosphorus are preferred.

Using the correct oil is more important than adding aftermarket additives to an unknown oil formulation.

Why Doesn't Every Oil Contain High Levels Of Zinc?

Many modern passenger vehicle oils have reduced levels of zinc and phosphorus to help protect catalytic converters and meet emissions requirements.

Because of this, performance engines often utilize oils specifically formulated for:

  • Performance use
  • Racing applications
  • Break-in procedures
  • Classic vehicles

What Oil Does BluePrint Recommend?


Break-In Oil

BluePrint recommends:

BPP710 Break-In Oil

This oil is designed to support proper ring seating and break-in procedures.

Service Oil

After break-in, BluePrint recommends:

BPP10W30 Performance Engine Oil

Follow the recommendations for your specific engine application.

Should I Add Extra Zinc To My Oil?

Not necessarily.

Adding zinc additives to an oil that already contains the correct additive package may alter the oil's chemistry.

It is generally best to:

  • Use a high-quality performance oil
  • Follow the oil recommendations for your engine
  • Avoid mixing additives unless specifically required

Is Zinc Only Important During Break-In?

No.

While zinc is often discussed during break-in, anti-wear protection remains important throughout the life of the engine.

Using quality engine oil and following recommended service intervals helps ensure long-term durability.

What Happens If I Use The Wrong Oil?

Using oil that does not meet the engine's requirements may contribute to:

  • Increased wear
  • Reduced protection
  • Higher operating temperatures
  • Shortened component life

Always verify the correct oil recommendation for your application.

Frequently Asked Questions

Can I use a zinc additive with conventional oil?

Possibly, but BluePrint generally recommends using a quality oil formulated for performance applications rather than relying solely on aftermarket additives.

Does every BluePrint engine need break-in oil?

Yes. Follow the recommended break-in procedure and oil recommendations supplied with your engine.

Is zinc important after break-in?

Yes. Proper anti-wear protection remains important throughout engine life.

Can too much zinc be harmful?

Excessive additives can alter the oil's intended formulation. Always follow product recommendations.
