Penrite 10 Tenths Running-In Oil 15W-40 (Mineral)

Description

This running-in oil from Penrite’s 10 Tenths line is designed for the critical early miles of engine operation, where controlled wear and proper piston ring seating are essential. It is a mineral base oil (not synthetic), with a High Zinc additive pack (exceeding 1600 ppm) to support camshafts, rockers, followers, and pushrods during the bedding period.

It is non friction-modified, meaning it does not include friction modifiers that could interfere with the run-in process.

Suitable for use in on-road, off-road, competition, and motorcycle engines (including wet-clutch setups).

Key Features & Benefits

• SAE Viscosity: 15W-40

• Base Oil Type: Mineral

• Additive Package: High Zinc (> 1600 ppm) for superior protection of valve train during break-in

• Non Friction-Modified: Allows the normal run-in / bedding process to occur without interference from friction modifiers

• Low Detergent & Low Dispersant: Reduces interference with ring seating

• Compatible Viscosities: Can be used where SAE 15W-40, 20W-40, 20W-50, or SAE 30 are acceptable

• Multi-use: Suitable for petrol, diesel, LPG, competition engines; also usable in motorcycles with wet clutches

• Engine Protection During Run-In: Helps prevent glazing of cylinder bores and protects moving parts under high stress conditions.

Application & Usage Guidance

• Use during initial engine break-in / run-in period — apply this oil for the first ~500 km (or as recommended) before switching to a standard or higher performance oil.

• Change oil and filter after run-in period, to remove break-in debris and deposits.

• Avoid overuse of friction modifiers or detergents during this phase, as they can delay ring seating.

• Although suited for a wide range of engines (petrol, diesel, LPG, competition), always confirm compatibility with the engine / manufacturer’s requirements.

• Because of high zinc content, this oil is especially suited for engines without catalytic converters; for engines with cat / aftertreatment, check suitability.

• For motorcycle systems with wet clutches, verify that there’s no adverse clutch action — generally compatible.
