The final step to building an engine is starting it for the first time.

Driven Break-In motor oils are formulated specifically for Break-In and provide the best foundation for high horsepower output, cooler running and longest engine life of your new, crate or rebuild engine. Also use for new camshaft installations/swaps. 

High ZDDP levels and Ultra Low Detergent levels optimized for break-in of both flat tappet and roller camshafts. 

Formulated to provide “controlled wear” to occur between the cylinder wall/ring interface while maintaining wear protection and faster ring seal. 

We recommend running our break-in products for the initial 30 minutes, then drain and replace with new break in oil and change filter. Run for 300 miles max.
