Driven GP-1 Break-In SAE 30 is a conventional break-in oil with a high-zinc, low-detergent additive package. The low detergent level lets the ZDDP adhere directly to ferrous wear surfaces, promoting proper ring seating and protecting flat tappet and roller valvetrains during initial start-up and break-in.

FAQ
What is GP-1 Break-In SAE 30 used for?
It is a dedicated break-in oil that helps seat piston rings and protect the cam and lifters during the first start-up and break-in period.
Why is the detergent level low?
A low detergent level lets the zinc (ZDDP) anti-wear additive bond directly to ferrous wear surfaces for added scuffing protection during break-in.
Is it a long-term street oil?
No. It is intended for break-in only. After break-in, the engine should be switched to a standard Driven Racing Oil.
