Drydene DRF­® Shakedown SAE 40 Break-In Oil

Part #D15101

DRF™ SHAKEDOWN SAE 40 BREAK-IN OIL is formulated with premium mineral base oils and Competition-Grade ZDDP™ to facilitate proper and lasting protection to key engine components during the initial run-in process when metal surfaces have not yet been lubricated through engine firing.  It is ideal for both new and rebuilt engines to deliver a potent dose of zinc and phosphorous, two of the most important compounds that camshafts, lifters, piston skirts, bearings and seals need during the critical break-in period to ensure that they are adequately and protected for on-track competition.

3/1 Gal Case, 5 Gal Pail

Product Applications

DRF SHAKEDOWN SAE 40 BREAK-IN OIL is designed for use in new and rebuilt circle track engines running gasoline, racing gasoline or alcohol for both dyno and on-track break-in periods. Combined with proprietary chemistry that resists wear and promotes correct ring sealing, the unique formula of DRF™

Shakedown allows for the oil to remain in the engine after a dyno break-in runs for added break-in time on the track for up to 50 miles. This can be done after the engine is fully broken-in (rings, valvetrain
and camshaft) with the DRF Shakedown Break-In Oil prior to competition on track. Oil and engine should be monitored closely for no unusual fuel dilution and/or coolant leakage into the oil during
the break-in process (dyno or track).

DRF Shakedown is the recommended break-in oil for use before changing to DRF A-Main Synthetic or DRF A-MAIN Synthetic Blend track oils after the break in process.

DRF Shakedown oils are tinted blue to easily identify its presence in engines before changing to DRF A-Main oils for competition.

Features & Benefits

DRF SHAKEDOWN SAE 40 BREAK-IN OIL features highly refined base oils and a specialized formula of anti-wear additives to ensure the highest level of surface protection during the engine break-in process. It  contains fast-acting, Competition-Grade ZDDP™ which provides superior protection to flat tappet cams, roller cams, hydraulic lifters, crankshafts, bearings and other critical metal components.

The DRF SHAKEDOWN formula:
• Delivers optimum ring sealing and cylinder pressure during initial run in
• Protects fresh metal surfaces that have not yet been lubricated prior to engine startup
• Promotes rapid air bubble dissipation and resists foaming to prevent insufficient lubrication in bearings and valves
• Inhibits the formation of deposits during the beginning stages of the break-in process
• Protects critical engine surfaces from rust and corrosion during extended storage periods or inactivity
