Please use the following Break-in Procedure to ensure optimum performance of your replacement Rev6 product.

• Use fuel with an octane of 87 or higher.
• Oil must be high in Zinc and Phosphorus! Do not use any full synthetic oils for the first 25 hours of run time.
  • Brands that work well:
  • Royal Purple
  • Comp Cams Break-In Oil
  • Lucas Hot Rod Oil
  • There are other various oils high in Zinc that will work
• Check oil level, add oil if necessary for the first 25 hours of run time.
• Once Rev6 product is started, bring RPM’s to 1,500-2000 RPM for 6 Minutes.
• Drive slowly first, bringing the Rev6 product up to operating temperature.
• Engines must be broken-in under a load! Running these machines with no load can cause the cylinders to glaze up and not seat in properly, causing engines to lose oil during normal operation.
• Vary throttle positions. Do not operate at sustained idle or sustained high speed.
• Perform regular checks on all fluids, controls, and bolt torques.
• Pull a variation of light and heavy loads during Break-In.
• Change Engine oil and filter after the first 5 hours of operation.
• Change oil after the Break-In period at 25 hours. (At this point you can switch back over to any recommended full synthetic oils.
