Driven Racing BR40 10W-40 High Performance Break-In Oil - Quart
High Zinc & Phosphorus 10W-40 Break-In Motor Oil for Gen III & IV LS 4.8L 5.3L 5.7L 6.0L 6.2L 7.0L Engines
Protect your fresh LS engine build from its first startup with Driven Racing Oil BR40 High Performance Break-In Motor Oil. This SAE 10W-40 break-in oil uses the same high-zinc and phosphorus formula as Driven Racing Oil’s original break-in oil, giving modern OEM rebuilds and hydraulic lifter engines the anti-wear protection needed during initial operation. BR40 promotes ring sealing, requires no additional ZDDP additives, and is built for dyno pulls, short-term racing use, or up to 400 miles of street break-in before changing to the appropriate long-term engine oil.
Key Features & Benefits
- SAE 10W-40 Break-In Viscosity: Driven Racing Oil BR40 is formulated in a 10W-40 viscosity for modern OEM rebuilds, hydraulic lifter engines, and performance combinations that benefit from this oil weight during initial run time. It provides a purpose-built break-in option rather than relying on a standard service oil for a fresh engine’s critical first operating period.
- High Zinc and Phosphorus Formula: BR40 uses the same high-zinc and phosphorus additive package as Driven Racing Oil’s original break-in oil. This added anti-wear protection helps support critical internal components during initial startup, camshaft break-in, dyno operation, and the early street miles of a newly assembled engine.
- Promotes Effective Ring Seal: Proper ring seating is a key objective during the break-in period, and BR40 is formulated to promote excellent ring sealing during initial engine operation. This makes it a strong choice for fresh LS engine assemblies where compression development and controlled early run-in are part of the build process.
- No Supplemental ZDDP Additive Needed: Driven Racing Oil BR40 is a complete break-in oil formulation and does not require separate ZDDP additives. This eliminates the need to mix supplemental additives into the oil before startup, helping builders keep their break-in lubrication plan straightforward and consistent.
- Built for Dyno, Racing, and Street Break-In: BR40 is suitable for full-power dyno pulls, one night of racing, or up to 400 miles of street break-in use. It gives engine builders and performance enthusiasts a dedicated oil solution for the period between first startup and the change to the engine’s regular service or race oil.
